This method should not be called on the main thread as it may lead to UI unresponsiveness.

+1 to same issue in xcode 14.2.

Facing the same issue, please Apple response & help the developers

I had the same message but with a different code. My code was: for item in items { guard let nsImage = NSImage(data: item) else { continue }   images.append(Image(nsImage: nsImage)) }

I resolved the message error with this:

DispatchQueue.global(gps: .background).async { for item in items { guard let nsImage = NSImage(data: item) else { continue }   images.append(Image(nsImage: nsImage)) } }

Hope this helps to everybody.

Thank you @amervil !

DispatchQueue.global().async { }

That is what did it for me!

For context: I was trying to run a simple apple script with NSAppleScript(..).executeAndReturnError(). The script was working just fine, but I was also receiving several of those "This method should not be called on the main thread.." errors in the console.

I'm getting these warnings all of a sudden, despite my code not changing for years, since updating to Xcode 15.3
