iOS 7 iPhone 5Apple’s early Christmas present is here for their iOS developers making them money on the Apple Store. The company on Friday seeded its latest version of iOS 7, iOS 7.1, to their developers. After updating to iOS 7.1 beta 2, developers will notice many new changes and fixes including faster animations, Touch ID and Passcodes moved to main Settings, and a new bounce animation and music labels in Control Center allowing you to see audio sources. You’ll also see a new list view redesigned calendar app. If you’re an iOS developer go download iOS 7.1 beta 2 from the dev center or update your device from the over-the-air update feature found in iOS.

Here’s the full change log showing notes, fixes, and main issues found in iOS 7.1 beta 2…

Notes and Known Issues
The following issues relate to using iOS SDK 7.1 beta 2 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.
Crash Logs
Fixed in iOS 7.1 beta 2
Crash logs now appear in Diagnostics & Usage Data in Settings.
Known Issue
If you create a new iCloud account during setup assistant, you may encounter an error when trying to enable iCloud Keychain.

Workaround: Select Setup Keychain Later in setup assistant, then enable iCloud Keychain in Settings.
Fixed in iOS 7.1 beta 2
Loading a large iTunes Match library should no longer take an especially long time to load.
Music App
Known Issue
Audiobooks fail to play.
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”>.

Known Issues
If a UITextField or a UILabel that is baseline aligned with constraints has attributes that change after the constraints have been added, the layout may be incorrect. The exception to this is -setFont: on UILabel, which should work as expected.Workaround: Avoid making changes in UITextField or UILabel after adding baseline-alignment constraints. If you must make changes, you should remove the constraints and then reapply them afterward. Note that this is a performance hit, so don’t do it unless it is necessary.
The backIndicatorTransitionMask from a storyboard or a xib will not be interpreted correctly at runtime.Workaround: Set the backIndicatorTransitionMask in code.
