I would expect this should work, but it seems as it has problems with type checking testDelegate?.actions.removeAll().

If I simply have a Button where I have a state variable bind to its .disabled modifier, then it works nice, as expected: struct TestView: View { @State private var saveEnabled: Bool = true var body: some View { Text("Tap me!") .onTapGesture { saveEnabled = !saveEnabled } Button("Save") {} .disabled(!saveEnabled) } } With this code snippet, when the user taps the text, the button is either enabled with blue tint or disabled with greyed out tint. But when I try to do the same within a presented alert, it does not work. My use case is that I present a text field which is prepopulated with a non empty string and then I let the user to change that, but if that's empty, I don't want to let the user to save it, so I want to disable the Button. This concept works fine in UIKit with UIAlertController and UITextField - here I'm not sure why doesn't it work. Code snippet: struct TestView: View { @State private var saveEnabled: Bool = true var body: some View { Text("Tap me!") .onTapGesture { presentAlert = true } .alert("Change name", isPresented: $presentAlert, actions: { TextField("", text: $name) .onChange(of: name) { newValue in saveEnabled = !newValue.trimmingCharacters(in: .whitespacesAndNewlines).isEmpty } Button("Save") {} .disabled(!saveEnabled) } ) } } Should I file a ticket in Feedback Assistant or is there something I'm overlooking? Thanks.

I have a framework (MyFramework) in which I want to use an existing dynamic framework via SPM (called now MyDynamicFramework). I included it as a package dependency and all seems to be good: Then, I created a test application in which I simply include my framework with Enbed & Sign. When I run this test application, it all works fine in simulator, but in real device I get the following signing-related issue: dyld[24248]: Library not loaded: @rpath/MyDynamicFramework.framework/MyDynamicFramework Referenced from: <ED356026-4AD8-3AD4-9CD7-BE977EE551E4> /private/var/containers/Bundle/Application/432B2A6D-55A7-4C9D-8EA2-622B81E215EA/MyFrameworkTestApp.app/Frameworks/MyFramework.framework/MyFramework Reason: tried: '/private/var/containers/Bundle/Application/432B2A6D-55A7-4C9D-8EA2-622B81E215EA/MyFrameworkTestApp.app/Frameworks/MyDynamicFramework.framework/MyDynamicFramework' (no such file), '/private/var/containers/Bundle/Application/432B2A6D-55A7-4C9D-8EA2-622B81E215EA/MyFrameworkTestApp.app/Frameworks/MyFramework.framework/Frameworks/MyDynamicFramework.framework/MyDynamicFramework' (code signature in <2BD920A5-1906-31B6-99B9-18DE47F02514> '/private/var/containers/Bundle/Application/432B2A6D-55A7-4C9D-8EA2-622B81E215EA/MyFrameworkTestApp.app/Frameworks/MyFramework.framework/Frameworks/MyDynamicFramework.framework/MyDynamicFramework' not valid for use in process: mapped file has no cdhash, completely unsigned?

Am I missing some settings? I thought that Embed & Sign should have solved the issue but it didn't. Thanks. It seems that it works if I embed the MyDynamicFramework in my test application as well, even thought that's already embedded into the framework (MyFramework) that I'm using. I don't see why should I do that, isn't that including the same dynamic framework twice?
