As stated Xcode is quiting unexpectedly when I try to open MainMenu.xib to edit my interface. The project still compiles and runs OK though.
I haven't worked on the project for a while and it's been a couple months or so since last opened and Xcode has updated a couple times since.
The project was updated to recommended setting when opened, plus I tried cleaning the project but to no avail.
Below is the log generated. libobjc.A.dylib seems to be the culprit.

Created an objective C app that has an embedded wkwebview. I am using the loadHTMLstring to display a NSString created by the application, no external links are used (although it will load them).
When launched from Xcode in debug mode, the program works as intended. When I build a signed distribution package, it will work on the computer that built it. But when I take that build to another computer, the app will crash upon launch, not even opening the dialog. The crash log indicates that it is due to wkwebview.
Running macOS 11.2.2 on both machines, (last week 11.2.1).
I have the proper webkit library and framework linked.
Any thoughts.
Hi. I am a indie/hobby developer that has a "for purchase" app in the App store and from what I can tell from the legalese that makes me a trader.
I plan to simply de-list from the EU market, because I don't want my personal information displayed, and I don't make enough money off the app to warrant setting up a LLC, or PO box etc.
Will customers in the EU who have ALREADY purchased my app prior to de-listing still receive any updates I make to the App or are they gonna be SOL?
