Apple released its first iOS 8.3 beta to developers last month before iOS 8.2 had even been released. iOS 8.3 marks the first version of iOS in which Apple is holding public betas in an effort to broaden its tester base to spot and eliminate bugs.

We don’t know for certain when iOS 8.3 will officially drop but we imagine it will happen within the next two months since Apple is going to take the wraps off its next-gen iOS 9 update at WWDC 2015 in June.

Here are Apple’s full release notes for iOS 8.3 beta 4:

Notes and Known Issues The following issues relate to using iOS SDK 8.3 to develop code. App Extensions Notes App extensions need an arm64 slice to run on 64-bit devices. If you try to run the armv7 slice on a 64-bit device it won’t work.

Apps need to have an arm64 slice if the bundle contains a framework that both the app and the app extension link against. CarPlay Known Issue Outgoing Call Audio and FaceTime Audio may be choppy. Spotlight Known Issue 3rd Party keyboards may not be available for selection in Spotlight Search. Workaround: Reboot the device. UIKit Note When linking against iOS 8.3, any code that relies on layout information (such as the frame) of a UIButton subview when the button is not in the window hierarchy will need to send layoutIfNeeded to the button before retrieving layout information (such as button.titleLabel.frame ) to ensure that the layout values are up to date. For example, if you had something like this: UIButton *button = [UIButton buttonWithType:UIButtonTypeSystem]; // code that sets up the button, but doesn’t yet add it to a window CGRect titleFrame = button.titleLabel.frame; // code that relies on the correct value for titleFrame You now need: UIButton *button = [UIButton buttonWithType:UIButtonTypeSystem]; // code that sets up the button, but doesn’t yet add it to a window [button layoutIfNeeded]; // This is also safe pre-iOS 8.3 CGRect titleFrame = button.titleLabel.frame; // code that relies on the correct value for titleFrame

WatchKit Known Issue Creating an animated image using the UIImage method animatedImageWithImages:duration: and then playing the animation using startAnimating ignores the duration and plays back as fast as possible. Workaround: Use startAnimatingWithImagesInRange:duration:repeatCount: instead.
