iOS 9 Support
There's no reason this tweak shouldn't support back to iOS 9.0
It should be no reason, but is didn't work on iOS 9 actually. It seems app behave differently on iOS 9 and 10, which makes me confused. I've tried many method to make it work, but haven't figure it out.
Oh, interesting. Well, I'll play around with it and see what I can do. I assume you tried logging all calls to fileExistsAtPath:? Or do you not have an iOS 9 test device?
almost all path related methods in NSFIleManager NSData NSString etc. also fopen sysctl ...
I received some feedback of iOS 9:
available: iPhone7,1-9.0.2
not available: iPhone8,2-9.3.3 iPhone6,1-9.3.3
I also test it on iOS 9.3.2 of iPhone SE. Doesn't work.
Hmmmm interesting. Well if I were you I'd leave this issue open and mark it as "help wanted". I'll keep trying in the meantime
They must be checking something else first, because they're not checking for the existence of any files outside the app's container before the app is terminated. That's all I got so far.
