I did not find any better way than recreate the QRCode from its text.

Thanks for the feedback. You should file a bug report against documentation. Good continuation.

Thanks for feedback. Print usually doesn't create crash, unless you unwrap a nil inside…

I understand. But how is it codeExists is never set true ? And once again, "stacking" several .alert should not work, as far as I tested.

If you miss one of the files in ru.lproj, that could cause the problem. What does Appstore says about the number of languages in your app ? Does it say "English and one more" ? It should. PS, sorry to ask: of course you search for russian name when in russian ?

However, if I move… what do you expect and get ?

Great, thanks for feedback. What you will see is that this code does not work properly if you move the insertion point somewhere in the text. You need some extra code, using the content of range to handle properly. But that may be unneeded complication in your case. You should also take care of the locale: separators depend on local, as well as decimal point. Good continuation.

Please post code in Answer area, not comments, they come out totally unreadable.

logic is attached.

What is the name of your game ?

My mistake, sorry. completionHandler: (granted: Bool) is executed in another thread, hence no change. Did you look at wait/async pattern ? Or you could also use a semaphore that will be cleared in the completion handler.

Using Version 13.2.1 (13C100). But the pattern I explained was first implemented on Xcode 12 or may be even 10. It is all in IB, so nothing to do with Swift or objC. Did you try to repeat each step as I did ? Specially "added constraints for the image size => this is required to remove the red warnings". Otherwise, have you a sample code you could send ?

I mean't Minimap of course (but spell checker did't see it that way…)

@HayesLiang Do you get result in a JSON format ?

Great, with your help it will move rapidly for sure. But, in a sense it is comforting for all of us developers. We are not the only one who leave bugs in our code… 😏
