I have observed behavior of app in iOS 10.2.1 device and iOS 10.3 beta 3 device for https://developer.apple.com/library/content/samplecode/GenericKeychain/Introduction/Intro.html
Keychain data is being deleted in iOS 10.3 beta 3. That was still found in earlier versions.
Do we have any alternative to do this?
