Netflix made me do that. Wtf! That's what QR codes are good at

I tell people "You are absoluty right" – but not exactly for the same reasons as the LLM

As a result: the app version 1.3.15 to be released this week does not crash anymore, its Share extension capability is safe, and there is now an alternative flow directly in the main app's home screen.

Then I pinpointed the exact line of code that was crashing. It was **not** the "Open containing app" call. It was a line of code that determined which "Host app" (Photos, Safari, etc.) was being used to share the resource from. **This** is now punished with a crash.

I hastily worked on an alternative flow where the user opens the main app, selects images with a picker, then scans. Not super convenient, but at least the existing user base would have a workaround at hand to keep sending things to the computer.

With Cool Maze consistently crashing in iOS 26, I thought the rule "Don't open the containing app" was now enforced. This would be the end of the app as we know it: no more Share with > Cool Maze > Scan.

As a workaround, the Cool Maze Share extension opens its "Containing app", which does have access to the camera. Opening the Containing app is a grey area, it's unclear if it's supported by Apple or not, but it works fine.

In iOS 26, sharing with Cool Maze just crashes. That's bad.

A Share extension in iOS has limited capabilities, e.g. it can't use the phone's camera. But the camera is needed in Cool Maze to scan to destination QR code.
