App crashes while not connected through Xcode

Question

I got strange behavior for iOS App. My App crashes only when it is not connected through XCode. Also, It crashes only after coming from back ground to foreground. I just gone through the crash log, as many links suggested to do that.

I am now unable to find out what the crash log says.

Can anyone here read this and hint me towards some solution or work arounds ??

Answer 1

Try add a NSZombieEnabled. For to do this:

1) Press cmd + Shift + ,

2) In left panel click a "Run {app name}"

3) At right choose Diagnostics"

4) Set checkbox at "Enable Zombie Objects"

5) Retry a crash, then you can debug a error with XCode
