Sometimes after app install, app won't start


(Gert Jan De Jonge) #1

I am trying to find why sometimes our app will not correctly start after a clean install. This is blocking my progress to beta testflight in the app store as for some reason the review team has this continously.

I tried adding some logging, but the logging part i added in the Main class is not reached when this happens.

The reason review is not accepted:
Termination Description: SPRINGBOARD, scene-create watchdog transgression: exhausted real (wall clock) time allowance of 18.82 seconds | | ProcessVisibility: Foreground | ProcessState: Running | WatchdogEvent: scene-create | WatchdogVisibility: Foreground | WatchdogCPUStatistics: ( | “Elapsed total CPU time (seconds): 7.360 (user 7.360, system 0.000), 18% CPU”, | “Elapsed application CPU time (seconds): 0.771, 2% CPU” | )

this last line is repeat until line 510, so it looks like a loop in MOE ?

Although it is called a crash report, it is not an actual crash, but a failure to load the primary screen on time.

I can recreate this only occasionally by removing/installing the app ( say about 1 in 20 times or so )

Is this a known problem with a possible fix, if not is there a way to debug the process before the Main class is reached ?

I am using MOE-sdk-1.4.2 with the latest xcode 9.3 (9E145)
