Apple releases iOS 7.1 beta 4, release notes inside

Apple today has released the fourth beta of iOS 7.1, the next incremental but noticeable update to iOS 7. You’ll find the release notes below. The public release of iOS 7.1 is expected to be available sometime next month.

Release Notes

The following issues relate to using iOS SDK 7.1 beta 4 to develop code.


Known Issue

32-bit apps running on a 64-bit device cannot attach to BTServer.



A compatibility behavior has been added to address an issue where some web servers would send the wrong Content-Length value for “Content-Encoding: gzip” content. Previously, NSURLConnection and NSURLSession would send a “network connection was lost” / NSURLErrorNetworkConnectionLost (-1005) error in this situation.

The compatibility behavior applies only if the Content-Length value exactly matches the expanded gzip’d content. It won’t apply for “off by 1” or similar miscounting.


Fixed in iOS 7.1 beta 4

Messages no longer indicates a send failure immediately after sending.



A property, minimal-ui, has been added for the viewport meta tag key that allows minimizing the top and bottom bars on the iPhone as the page loads. While on a page using minimal-ui, tapping the top bar brings the bars back. Tapping back in the content dismisses them again.

For example, use <meta name=”viewport” content=”width=1024, minimal-ui”>.
