I've just uploaded an iOS app to App Store Connect and received the following warning
Distribution completed with warnings:
App Store Connect Operation Warning
ITMS-90339: Deprecated Info.plist Key - The Info.plist contains a key 'UIApplicationExitsOnSuspend' in bundle _______ [_______.app] that will soon be unsupported. Remove the key, rebuild your app and resubmit.
I saw on another forum that this key was deprecated in the latest iOS beta: https://developer.apple.com/document..._release_notes
The UIApplicationExitsOnSuspend key is no longer supported in iOS & iPadOS 13. Update your apps to handle modern multitasking.
