Unfortunately I cannot reproduce this. The attached message log is not very useful. There are a lot of irrelevant messages. After filtering them out and retaining only those containing AmiKoDesitin (with a trailing Tab) we see that after the call to cancelCamera: there is nothing useful, and 35 seconds later, a message XPC connection interrupted. Maybe a more informative log could be captured by launching the app from Xcode, possibly compiling the DEBUG version.

ok, will send you the log.

This is where it hangs when iPhoneX is connected:

The title says the issue is with an iPad, but the log above is for when an iPhoneX is connected. Still, there is nothing unusual in that log. There is no indication that it crashes, no exception or error message.

zdavatz commented 6 years ago

Ok, I will test with 2.9.32. Actually it does not crash anymore, it just hangs for some time and then continues to work normally.

bettar commented 6 years ago

On my iPhone 8 it doesn't hang.

zdavatz commented 6 years ago

On iPhone X after hitting the Cancel Button, the CPU stays at over 90% and the memory just keeps growing. Looks like you have to release something differently for iPhone X.

Exactly the same happens on iPad as well.

zdavatz commented 6 years ago

there is no more crash. Just a hang now.

bettar commented 6 years ago

I cannot reproduce it because I don't have the physical devices. On the simulator (iPad Air) the CPU stays at 0% after hitting Cancel.
