hello:
I have a strange problem. When my app is tested with testflight, the iOS9 device installs the app. After launching, it will flash back immediately, but iOS11 and iOS12 will not. When I viewed the log using the console that came with my Mac, I found:
1, deny (1) file-write-create / default.profraw
2, deny (1) file-write-create /private/umTest_Jailbreak.txt
3. SecTrustEvaluate [leaf AnchorTrusted]
I don't know what these three logs mean?
In addition, this kind of flashback on iOS9 started from yesterday and has not been there before.
