Please just post the ContentView file ? The one you call from SceneDelegate. Anyway there are files missing in the attached github.

Does it work now ? If so, don't forget to mark the correct answer to close the thread.

you place it anywhere at top level, outside of any class.

Note that notification will work only if FirstViewController is loaded when you tap in SecondViewController (that is the case if you are in a navigation stack or if you present modally). Otherwise, you could save to userDefaults (in SecondViewController) and read userDefaults to set the button1 enabled or disabled in viewWillAppear in FirstViewController

So please show complete code, for instance of          struct remi5en250

Complete code, I mean the view including the switch as well as the views you call. And most important, the error code. You can also attach a textFile with the attach button just below the editing frame in this page (rightmost icon ∞)

Yes, you can do the same. But if you are to use in many places, environment var are probably a better choice.

Thanks. But if you need more help, please give more details.

If you cannot share code, it is really hard to help. Good luck.

But you can do it !

I tried to set on the UITextField class, with         DispatchQueue.main.async { UITextField.appearance().autocapitalizationType = .words }  in viewDidLoad  but did not succeed yet.

At the bottom of this page, you have a FeedBack and bug report link (in the Support section). Please report the bug number here, in case.

There are developers on the forum who don't pay developer fees.

I also tested in MacOS 12.3.1, Xcode 13.3.1, iOS 15.4 simulator. Works OK. Did you reboot the Mac, in case ?

For the first part of the question, please show code.
