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

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?

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.
The following code results in a segmentation fault and crashes the copmpiler:
struct Action {
var intVar: Int
var strVar: String
}
protocol TestDelegate: AnyObject {
associatedtype ActionType
var actions: [ActionType] { get set }
}
class TestDelegateImpl: TestDelegate {
typealias ActionType = Action
var actions: [Action] = []
}
class TestViewController {
var testDelegate: (any TestDelegate)?
func testFunc() {
testDelegate?.actions.removeAll()
}
}
let tVC = TestViewController()
tVC.testDelegate = TestDelegateImpl()
tVC.testFunc()

Anyone experienced this, or do I overlook somethinig? I would expect this should work, but it seems as it has problems with type checking testDelegate?.actions.removeAll().
