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… 😏

Unfortunately, the only answer I ever got is 'it depends'… Did you do a Clean Build Folder and reboot the Mac ?

This is not clearly explained in the docs. : Effectively, I looked for it but could not find it in the convenience init(plane:classification:minimumBounds:) doc page.

You can find previous version of Xcode here, if you need for testing purpose: https://xcodereleases.com .     Did you first try to reboot and reinstall ?

Completed SO.

Great. Thanks for feedback. Don't forget to close this long discussion by marking the correct answer ? One lesson to remind: print statements are a wonderful debug tool ! Have a good day.
