If you're not satisfied by the help and the solution, the best is that you search and find a better solution by yourself. Good luck.

To get a better result (having "Std" appear during scrolling and disappearing from previous selection, you need to intercept the scroll position. See discussion here:      https://stackoverflow.com/questions/5237696/read-position-of-uipickerview-while-scrolling

@Mandar Pathak I think answer is in eskimo's: This can change from release to release, as Apple imports new versions of CLDR

Thanks, I learned something. But it could be useful for doc to remind it.

No, when you declare a computed var, you have to declare type. If you try without, you'll get an error: computed property must have an explicit type

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 !
