iOS 13 BUG crash

[Dave181295]

iOS 14 & 15 working correctly, but on iOS 13 We keep getting

Fatal error: Accessing State<Bool> outside View.body: file /BuildRoot/Library/Caches/com.apple.xbs/Sources/Monoceros_Sim/Monoceros-24.4/Core/State.swift, line 44

Xcode complaining about this line from the library's code :

        Coordinator(text: $text,
                    isFirstResponder: externalIsFirstResponder ?? $internalIsFirstResponder,    <-- HERE
                    onBeginEditing: onBeginEditingHandler,
                    onEditingChange: onEditingChangeHandler,
                    onEndEditing: onEndEditingHandler,
                    onClear: onClearHandler,
                    onReturn: onReturnHandler)
  }

Here our code :

       iPhoneNumberField("xxx-xxx-xxxx", text: $phoneNumber)
                    .defaultRegion("IL")
                    .font(UIFont(name: "Poppins-Medium", size: idiom == .pad ? 30 : 20))
                    .textFieldStyle(.none)
                    .prefixHidden(false)
                    .maximumDigits(10)
                    .flagHidden(true)
                    .flagSelectable(false)
                    .clearsOnEditingBegan(true)
                    // .multilineTextAlignment(.leading)
                    .introspectTextField { textField in

                        if let text = textField.text, text.isEmpty {
                            textField.becomeFirstResponder()
                        }
                }

We are pretty sure its a bug from the library What's your thoughts?

Is this library still maintained ?

Looks like you are setting internalIsFirstResponder outside of the body! You must never change the @State from outside. try making it private to find where is the cause of this bug

[Dave181295]

Thanks, This one is resolved we just changed the order of the modifiers, but looks like there is another one coming from the internal files of the library

We are not using the State property outside of the body we declare the instance of PhoneNumber in a var phoneView: some View {} then just calling it in the body

var body: some View {

phoneView
}

Update

Even with a constant String its crashing

  iPhoneNumberField(nil , text: .constant("********"))

Pretty sure it's coming from the lib, can you take a look ?

Greetings,

Can you provide an example project?
