问题 I'm implementing Sign in with Apple and noticed that the email and fullName properties of the returned ASAuthorizationAppleIDCredential are only filled on the very first Sign-In for this Apple ID. On all subsequent Sign-Ins those properties are nil. Is this a bug on iOS 13 or expected behaviour? Here is the code I'm using to start the request: @available(iOS 13.0, *) dynamic private func signInWithAppleClicked() { let request = ASAuthorizationAppleIDProvider().createRequest() request

问题 I have a Mac early 2011 running MacOS high sierra 10.13.6. My Mac can't upgrade to higher MacOS versions. I need to install XCode 11 to take advantage of SwiftUI.

So you cannot install Xcode 11 on macOS 10.13.6 回答2: Upgrade old macbook pro using this patch http://dosdude1.com/mojave/.

I have not figured out a good way to position the player so that it is flush above the Tab Bar, since the Tab Bar height changes based on device. The main issue I've found is just how I have to position the player in an overlay or ZStack in the root view of my app, instead of within the TabView
