Apple releases iOS 7 beta 2, release notes inside

As expected, Apple has released iOS 7 beta 2. In addition to the changelog that can be found below, Mac Rumors has outlined a number of visual changes that general users would like to know about. These can also be found below. In general, though, the more major updates in beta 2 include iPad support for the first time as well as the return of Voice Memos.

General Changes

Again, these changes come courtesy of a post outlined by Mac Rumors regarding beta 2:

Welcome Screen: iOS 7 beta 2 introduced a new Welcome Screen that asks for an iCloud password, allows users to turn on iMessages and choose associated email addresses, and set up a passcode on the device.


Voice Memos: The Voice Memos app was missing from the first iOS 7 beta, but with beta 2, the app has returned and is now fully functional.


Find My iPhone: The Find My iPhone setting in iCloud now offers up new language that specifies that the app will help users “remotely locate, lock, erase, and prevent re-activation” of a lost iPhone.

Siri: Siri requests seem to load much faster with the new iteration of iOS 7 and there are also male and female voice options available. These can be accessed in the General Settings under the Siri heading, which offers a new Voice Gender option. While male and female voices have been available in other languages, this is the first time English male/female voices can be activated.


Control Center: Parts of the Control Center have had a slight redesign, with a new clock icon. The icon, which was previously dark, is now a simple clock outline.


Notifications: Some iOS 7 users were having issues with double notifications, which appears to have been fixed with beta 2.


Reminders: Reminders has had a slight redesign with a new list layout that is more compact than the previous layout, and a new clock icon next to the search bar will allow users to locate scheduled reminders.


iCloud: iCloud Backups are now available once again. The first iOS 7 beta did not support automatic backups.


Spotlight: Searching via Spotlight is much quicker, with results being displayed almost instantaneously with far less of the lag that was present in the first beta.


Messages: The Messages “Send” button is bold and turns green or blue when text is typed. There’s also a new bubble animation shown when messages are sent. Swiping to the left on a message will display time stamps. Group chats in Messages also display contact photos next to texts.


Music: The music app has seen a number of bug fixes to correct interface errors and other issues. Lock screen album art has also been repaired for the iPhone 4/4S.


Weather: In the weather app, a new icon on the bottom right of the screen brings up a listing of the weather in all of the cities tracked in the app.


Multitasking: Swiping up to close out apps works much more smoothly on the iPhone 5 following the update to beta 2.

Beta 2 Release Notes


iOS SDK 7.0 provides support for developing iOS apps, and it includes the complete set of Xcode tools, compilers, and frameworks for creating apps for iOS and OS X. These tools include the Xcode IDE and the Instruments analysis tool, among many others.

With this software you can develop apps for iPhone, iPad, or iPod touch running iOS 7. You can also test your apps using the included iOS Simulator, which supports iOS 7. iOS SDK 7.0 requires a Mac computer running OS X v10.8.4 (Mountain Lion) or later.

This version of iOS is intended for installation only on devices registered with the Apple Developer Program. Attempting to install this version of iOS in an unauthorized manner could put your device in an unusable state.

Notes and Known Issues

The following issues relate to using iOS SDK 7.0 to develop code.



AirDrop in iOS 7 Seed 2 is not compatible with AirDrop in iOS 7 Seed 1.

Contacts Only support requires that:

  • You are logged into iCloud.
  • The sender and receiver have each other’s Apple ID email addresses in Contacts on their devices.

Fixed in Seed 2

Occasionally, AirDrop will exhibit unreliability in discovery and/or data transfer to peers over Wi-Fi.

Known Issues

  • Contact Only currently requires that you have an active Internet connection.
  • The App Store should support the ability to find an app capable of opening a received document based on the document’s Uniform Type Identifier (UTI). Currently, just a blank screen is displayed.


Known Issues

  • When sending music to an Apple TV, advancing to the next track may fail.
  • Audio volume may increase dramatically and unexpectedly during AirPlay.

AV Foundation


AVCaptureSession now uses your app’s AVAudioSession by default.

Fixed in Seed 2

AVCaptureSession is unable to produce samples to its AVCaptureAudioDataOutput when the app is running in the background.


Fixed in Seed 2

Edits made to iCloud Calendar events off-device will not push to the device.

Workaround: Update the calendar manually or trigger a fetch by modifying an event on-device.

Car Display

Known Issues

Support for Car Display will be provided once compatible systems are available.


Known Issues

Some high-resolution photos will not sync (via iCloud and other services) when set as a Contact’s Caller ID photo.

Workaround: Use a lower-resolution photo.

Core Animation


When the UIViewGroupOpacity key is not present, the default value is now YES. The default was previously NO.

This means that subviews of a transparent view will first be composited onto that transparent view, then the precomposited subtree will be drawn as a whole onto the background. A NO setting results in less expensive, but also less accurate, compositing: each view in the transparent subtree is composited onto what’s underneath it, according to the parent’s opacity, in the normal painter’s algorithm order.

Core Data

Fixed in Seed 2

Moving data from a local sandbox to iCloud using migratePersistentStore causes a crash. Instead, manually migrate the data store by iterating over the objects in the local data store file.

Game Center

Fixed in Seed 2

  • When adding new Apple IDs to Game Center, they must be added through the Game Center app and not Settings.
  • If you launch a Game Center app while not logged into Game Center, the Game Center login sheet may be unreadable.

Game Kit

Fixed in Seed 2

  • The API for sending reminders is present but unimplemented in this seed.
  • The API for loading leaderboard sets might need to be called a second time for it to succeed.



Activation Lock, a new feature of Find My iPhone, is turned on automatically when Find My iPhone is enabled on any device running iOS 7. Activation Lock requires users to enter their Apple ID and password to turn off Find My iPhone, sign out of iCloud, erase the device, or reactivate the device after an erase. It’s important to do one of the following before transferring a device to a new user:

  • Sign out of iCloud.
  • Turn off Activation Lock in Settings > iCloud > Find My iPhone.

Fixed in Seed 2

  • Signing out of an iCloud account with Find My iPhone turned on requires you to enter your Apple ID password. However, in some cases, the keyboard does not appear.Workaround: Double-tapping the home button will bring up the keyboard.
  • Sometimes when creating a new Apple ID and choosing to use iCloud in Setup Assistant, iCloud will not be turned on.Workround: Go to Settings/iCloud and sign in with your Apple ID.
  • When setting up iCloud Keychain, many iCloud Security Code candidates will be rejected for being too weak.Workaround: Choose a 4-digit iCloud Security Code that does not have an obvious pattern.
  • Restoring your device from the same device’s iCloud backup will lose all passwords for Wi-Fi, profiles, accounts, and apps.
  • When just Calendars or just Reminders is toggled off then back on again in iCloud settings, data may not resync to the device.Workaround: Turn off both Calendars and Reminders, and then turn them both back on.
  • Users cannot use Simple or Complex iCloud Security Codes to recover their keychain items from their secure backup on iPhone 4.Workaround: Use Random iCloud Security Codes to back up keychain items.
  • After users change their iCloud Security Code to Simple or Complex, they will not be able to recover their keychain items from the secure backup.Workaround: Change the country code field under Account Security so that the user can receive the SMS Verification Code to complete the recovery process.

Known Issues

  • If you have “Reset All Contents and Settings” on a device (Settings > General > Reset) that:
    • Has an iCloud account set up
    • Has Find My iPhone Activation Lock enabled
    • Has not previously navigated to Settings > iCloud

    you won’t be asked to enter your iCloud credentials to disable Activation Lock prior to erasing. After the device is erased, your device will be activation locked.

    Workaround: Delete the iCloud account prior to erasing the device. If in this state, enter your iCloud account credentials to unlock the device.

  • When setting up iCloud Keychain in Setup Assistant on iPhone 4 and iPhone 4s, the keyboard covers the iCloud Security Code entry field and the Advanced Options link.Workaround: Scroll down to see the hidden entries.
  • Users in Switzerland, France, Spain, Germany, Poland, Finland, and possibly some other countries, will be unable to restore their keychains using phone number validation.Workaround: Use a randomly generated iCloud Security Code.
  • If you change the country associated with a phone number in Settings > iCloud > Account Name > Keychain, you will not be able to view the changed country name/code.Workaround: Turn off Keychain Restore, and then turn it back on.
  • Credit cards deleted in Safari Settings > AutoFill are removed from the device but not from other devices.Workaround: Making another local change (like adding a credit card) will force the sync.
  • The keyboard is not present in the iCloud Keychain approval dialog after screen unlock.Workaround: Tap on either Don’t Allow or Allow. The keyboard will be presented the next time.
  • On rare occasions, users might experience difficulties setting up iCloud Keychain on some of their devices.Workaround: A temporary Reset iCloud Keychain button is available in iCloud Settings > Account > Account Security.
  • iCloud Keychain users who set up an additional device will receive an approval request to the other devices with iCloud Keychain turned on. The approval request will not be displayed if their screens are off and the devices are idle.Workaround: Wake up any peer device to accept the approval request.
  • Users signing out of iCloud by deleting their iCloud account, erasing all contents and settings, or erasing the device via Find My iPhone and signing back in will not be presented with the correct iCloud Keychain setup screens.Workaround: Use the seed-only iCloud Keychain Reset button.
  • Users who have a single device with iCloud Keychain on will not be presented with the correct iCloud Keychain setup screens after restoring from a backup.Workaround: Use the seed-only iCloud Keychain Reset button.
  • Nonpurchased ePubs and PDFs will not be restored when iCloud-restoring an iOS 7 device with a pre-iOS 7 backup. Purchased content will be restored without issue.Workaround: Use iTunes sync.
  • In iOS 7, Find My iPhone and Bookmarks toggles are no longer supported on secondary iCloud accounts. When you update your device with either of these options enabled on a secondary iCloud account, they will be turned off with no user notification.Workaround: Set up the primary iCloud account via Settings/iCloud and then enable Find My iPhone or Bookmarks.

Location Services

Fixed in Seed 2

  • In this seed, GPS-based location is nonfunctional on iPhone 4. This includes AGPS call flows used for 911 emergency services location requests. Wi-Fi and cellular-based location remain functional.
  • Location Services will be off by default after updating from prior releases. This prohibits Find My iPhone from working.Workaround: Turn on Location Services in Settings > Privacy > Location Services.



If the calls to renderInContext on the layer backing an MKMapView are made off the main thread, they should be eliminated or moved to the main thread. Failure to do so can cause an app crash. Instead of using renderInContext, use the newMKMapSnapshotter APIs.

Fixed in Seed 2

  • Using +[MKMapCamera cameraLookingAtCenterCoordinate:fromEyeCoordinate:eyeAltitude:] may result in the wrong map heading being chosen.
  • Using +[MKMapSnapshot pointForCoordinate:] returns the wrong result for nonsquare snapshots.


Known Issues

  • The existing Messages database may be deleted after a restore or upgrade if:
    • You do not sign in to iCloud during the Setup Assistant.
    • The iMessage and iCloud accounts use different IDs.
  • Messages app crashes after viewing any attachments on two separate threads.Workaround: The attachments are viewable after relaunching Messages.
  • On a clean install, launching Messages presents an empty message list instead of a new compose window.


Fixed in Seed 2

  • Silent pushes will always wake the device.
  • Currently, there is no API that lets you inspect the settings controlling your app’s background behavior.

Music Player

Known Issues

MPMediaPickerController has been disabled for this seed. It will immediately return as if the user canceled the selection.



  • Cellular fallback is a technology that will attempt to connect over the cellular interface when a connection over the Wi-Fi interface does not succeed. There are a number of cases where connection failures may occur over Wi-Fi, such as a cable modem in need of a reboot or a firewall that blocks access to certain resources.If your app restricts network operations over the cellular network, verify that your code is using the proper API to implement that policy.For example, if your app watches SCNetworkReachability for the kSCNetworkReachabilityFlagsIsWWAN to monitor when Wi-Fi is available, it may not behave correctly under cellular fallback.If an app uses this method and then attempts to connect, thinking it will get a connection over Wi-Fi, the app may inadvertently end up with a connection over the cellular network. The lack of the kSCNetworkReachabilityFlagsIsWWAN is not a guarantee that your connection will not go over cellular. If your code needs to enforce that a connection not go over cellular, it needs to specify that when making a networking request.Instead, for CFNetwork code using CFSocketStreamCFHTTPStream, or similar APIs, set the kCFStreamPropertyNoCellular property to true on the CF object before connecting.

    For NSURLRequests, call [request setAllowsCellularAccess: false].

    In addition to making sure your code will never be connected over cellular because of cellular fallback, this call ensures that your code will never be connected over cellular because of the VPN or convoluted routing problems (connecting to IPv6 over cellular because only IPv4 is available over Wi-Fi, etc.).

    To verify that your app is behaving properly, you should test against a broken Wi-Fi network. The easiest way to set up a broken Wi-Fi network is to set up an Apple AirPort Base Station or other Wi-Fi access point to hand out a DHCP address and leave the access point disconnected from the Internet. Another simple way of testing is to unplug the cable or DSL line from your cable or DLS modem.

  • Two low-level networking APIs that used to return a MAC address now return the fixed value 02:00:00:00:00:00. The APIs in question are sysctl (NET_RT_IFLIST) and ioctl (SIOCGIFCONF). Developers using the value of the MAC address should migrate to identifiers such as -[UIDevice identifierForVendor]. This change affects all apps running on iOS 7.


Known Issues

Newsstand background downloads that use HTTP basic or digest authentication will prompt the user with authorization alerts (NSURLConnectionDelegate callbacks for connectionShouldUseCredentialStorage andwillSendRequestForAuthenticationChallenge are not called correctly).

Nike + iPod

Fixed in Seed 2

The Nike + iPod app is now included.

Objective-C Runtime


Due to changes in how the isa field is implemented, *self may change during enumeration (for example, if the container is retained).

Workaround: When implementing countByEnumeratingWithState, do not set state->mutationsPtr = self.



In previous versions of the iOS SDK, Passbook did not validate the backFields on passes completely. This has been corrected, but it means that some passes added on iOS 6.0, 6.1, and iOS 7.0 Seed 1, will be invalid on iOS 7 Seed 2 and later. The validation rules have not changed, it was just a a bug in validation in previous implementations. If you have a pass that you were previously able to add to passbook, but no longer can, watch the console log for more than one field that has the key NAME. Field keys need to be unique.


Fixed in seed 2

Reminders may become unusable after the user creates a new list.


Fixed in Seed 2

  • Users cannot delete their passwords via Safari Settings > AutoFill.
  • The SafariServices addToReadingList API doesn’t work on devices. However, it works fine on iOS Simulator.
  • If a user deletes a saved credit card number (from AutoFill), it will still autofill.Workaround: After deleting a credit card from AutoFill, force-quit Safari or reboot the device.

Known Issues

  • Upgrading to iOS may reset Safari’s settings to their default values.
  • Safari website credentials do not always autofill between mobile and desktop versions.Workaround: Use the desktop version if the site offers it.



  • -[UIDevice uniqueIdentifier] is no longer accepted in submissions to the App Store. In iOS 7, apps that are already on the store or on users’ devices that call this removed API will no longer be returned the UDID. Instead, -[UIDevice uniqueIdentifier] will return a 40-character string starting with FFFFFFFF, followed by the hex value of -[UIDevice identifierForVendor]. It is important to consider how this will affect existing apps. Consider submitting updates that no longer access the UDID.
  • iOS now requests user consent for apps to use audio input on all iOS 7 devices. For devices sold in China, iOS will also request user consent for apps to use the camera hardware. The operating system will present the consent alert when you set the category of the instantiated AVAudioSesison. The AVAudioSessionCategories that will present the alert are AVAudioSessionCategoryRecord and AVAudioSessionCategoryPlayAndRecord.If the user doesn’t allow access, the audio session data will be all zeros (silence). For devices where camera access is requested and denied by the user, the video capture session is a black screen.
  • The API gethostuuid() has been removed and will not be accepted for submission to the store, regardless of the targeted OS. For existing apps running on iOS 7, the function will return a uuid_t representation of the vendor identifier (-[UIDevice identifierForVendor]).

Fixed in Seed 2

Changing the Require Passcode time setting after a restore from backup will require a reboot for the change to take effect.


Fixed in Seed 2

In Notification Center, when selecting an alert style for an app, the examples for None, Banners, and Alerts are not displayed.

Known Issues

In General > Background App Refresh, the per-app settings are not honored.


Known Issues

After erasing the device from Settings > General > Reset > Erase All Content & Settings, CrashReporter logs will no longer be copied from the device to the computer.

Workaround: Restore the device from an IPSW instead of using Erase All Content & Settings on the device.



This seed includes development versions of new male and female Siri voices for U.S. English and French, and a male voice for German.



Up through iOS 6, when using TWTweetComposeViewController and SLComposeViewController (the latter only for Twitter and Weibo, but not Facebook), if the caller supplies a completionHandler, the supplied completionHandler is responsible for dismissing the view controller. As of iOS 7, if the app links against the iOS 7 SDK, the view controller will dismiss itself even if the caller supplies a completionHandler. To avoid this, the caller’s completionHandler should not dismiss the view controller.

Known Issues

When using the iOS 6.1 SDK on OS X v10.8 Mountain Lion, if you use the iOS 5.0 or iOS 5.1 Legacy SDK in iOS Simulator, you will not be able to use Twitter features: attempting to sign in to Twitter via the Settings pane will fail, and Twitter.frameworkwill not work correctly. If you need to test Twitter features, you will need to choose either an iOS 6.1 or iOS 6.0 Simulator run destination, or you can test with iOS 5.x on a device.



  • Active touches are no longer canceled when the user takes a screenshot.
  • Dynamic wallpaper is not available on iPhone 4.

Known Issues

  • Some apps may receive duplicate push notifications or no notification at all.
  • The app switcher does not show all of the suspended apps.
  • Springboard crashes when accessing some web clips in the App Switcher.
  • Passcode Lock and Auto-lock time settings are not always respected. Sometimes the device does not require a passcode when the settings indicate it should.
  • When restoring from an iCloud backup on a device with hundreds of apps, Springboard may crash repeatedly.

Sprite Kit

Known Issues

+[AVPlayer playerWithPlayerItem:] returns an AVPlayer object, but the current item will return nil if the player was created on another thread.


Known Issues

The Wi-Fi sync option in iTunes is checked, but Wi-Fi devices do not appear in iTunes.

Workaround: On OS X, install the iOS 7.0 SDK after installing iTunes. Wi-Fi sync is not supported on Windows.



  • +[UIPasteboard pasteboardWithName:create:] and +[UIPasteboard pasteboardWithUniqueName] now unique the given name to allow only those apps in the same application group to access the pasteboard. If the developer attempts to create a pasteboard with a name that already exists and they are not part of the same app suite, they will get their own unique and private pasteboard. Note that this does not affect the system provided pasteboards, general, and find.
  • Starting with Seed 2, apps default to using the new view controller-based status bar management system. To opt out of this, add a value of NO for the UIViewControllerBasedStatusBarAppearance key to your Info.plist.
  • Blurred layers are not available on iPhone 4.
  • Parallax is not available on iPhone 4.
  • Letterpress text is not available on iPhone 4.

Fixed in Seed 2

  • Auto Layout constraints do not take bar height into account, which leads to issues during rotation or when the height of the status bar changes.
  • Print Center is not functional. Seeing print job progress, job name, or job preview icon is not available in this seed. To ensure that the job name is correct for print jobs, use the Printer Simulator app in Xcode and check the log.

Known Issues

  • IB support for -topLayoutGuide and -bottomLayoutGuide is not functional in this seed.
  • When a device without a passcode is connected to an untrusted computer, iTunes will tell the user to approve on the phone, yet the phone never asks the user to approve. The phone is trusted anyway, so there is no functional impact, but the UI is missing.
  • UIPickerView with custom views doesn’t show the views in the selection indicator.
  • UIRefreshControl and the associated table view are hidden under the navigation bar when setTranslucent: is NO.
  • UIButtonTypeInfoLightUIButtonTypeInfoDark, and UIButtonTypeDetailDisclosure buttons all look the same.
  • The UIImagePickerController does not show a live preview when using custom overlays.
  • When using Auto Layout to position a UIButton, if you set the content compression resistance or content hugging priority to minimum, the button will have ambiguous layout.Workaround: Don’t use a content compression resistance or content hugging priority of less than 2 for UIButton.
  • UISwitchonTintColors is always green irrespective of what it’s set to.
  • The title of the UIRefreshControl appears below the navigation bar.

USB Tethering

Fixed in Seed 2

Personal Hotspot (Internet Tethering) will not work if this seed of iOS SDK 7.0 is installed.

Voice Memos

Fixed in Seed 2

The VoiceMemos app is now included.


Fixed in Seed 2

  • Maps does not work with VoiceOver.
  • Siri and VoiceOver do not always work together properly.

Known Issues

Reminders does not work with VoiceOver.



Weather conditions are not animated on iPhone 4.



  • Previously, when the viewport parameters were modified, the old parameters were never discarded. This caused the viewport parameters to be additive.For example, if you started with width=device-width and then changed it to initial-scale=1.0, you ended up with a computed viewport of width=device-width, initial-scale=1.0.In iOS 7, this has been addressed. Now you end up with with a computed viewport of initial-scale=1.0.
  • Previously, when using <meta name=”viewport” content=”initial-scale=1.0, user-scalable=1″>, the scale could be incorrect after rotation.Now, if a user has not scaled the page explicitly, the page is restored to its initial scale. Also, the current scale is now correctly restricted within the min-scalemax-scale bounds.
  • Some images for Retina display devices appear at twice the size that they should instead of being scaled down 50%. This issue can also occur with any image to be scaled that is larger than its container and that uses either the background-sizeproperty or the -webkit-background-size property. This issue affects both native apps that display web content and web pages viewed in Safari for iPhone.The background CSS shorthand property now resets the value of the background-size property to auto when background size is not specified. This new behavior is per the CSS spec, and the old behavior is available only for apps linked to an SDK prior to iOS 7.0 when running on iOS 7 or later.Workaround: Specify the background-size property or the -webkit-background-size property after the background shorthand property in the CSS stylesheet for the web content being displayed.

Fixed in Seed 2

When scrolling a page with animations, the animations stop and do not resume when the scrolling has stopped.
