Seems that is the best and the "most correct" solution.

The simulator problem is sort of annoying and we want to test the feature on simulators. Have you already sent a bug report to Apple?

Cabled, or once you check Connect via network, through WiFi. Please remember that your app will run for a limited period (currently 7 days). After that you will need to re-install it with Xcode. And to run apps with some specific features (push notification, for example), you need a paid developer account.

Thanks for showing the code. (If you could show the sample screen shot, it was better.) But I cannot find any green (+) icon running your code on iOS 15.0 Simulator. Can you clarify how I can see it?

Thanks for adding the image and the description. But unfortunately, I do not know any ways to delete it. With easily understandable code and image, someone who knows how to do it (if possible) would find this thread more easily. Hope you can solve your issue soon.

It is not a problem of terminology. Selector is a completely different thing than function pointer. Internally, Selector contains a C-string representing the Objective-C style method name, no function pointer exists inside a Selector.

Thanks for reporting. If you have any further questions, please start a new thread including the code as text. Unfortunately, not many readers go deep into external links. Questions with enough info included as text, would get more attention from readers.

i got it resolved guys i upgraded my iOS it seems to be a known issue of iOS 15.0. About iOS 15 Updates page shows that in iOS 15.0.1, the issue Settings app may incorrectly display an alert that storage is full was fixed. You should better take enough time before marking an answer as SOLUTION. Many readers expect the marked answer would describe the right solution.

@MartinP7r, you should better start your own thread with including properly formatted code. Comments on a SOLVED thread would not get good attentions and not many readers would try a code with horrible formatting.

As I wrote as a comment, you should better start your own thread with your issue. The problem is another thing than asked in this thread.

Can you show what is your current locale?

The thread you have shown is marked SOLVED. So, the issue is SOLVED, isn't it?

@oleg48, you should better start your own thread including enough info.

You can write the prototype by yourself. But it is not recommended.

Please show your code as text, using Code Block.
