Xcode - My app crash and the error is "Invalid pointer dequeued from free list *** set a breakpoint in malloc_error_break to debug"

Question

My app runs perfect on simulator. But when I run it on device the app crash and display error :

"malloc: * error for object 0x17415d0c0: Invalid pointer dequeued from free list * set a breakpoint in malloc_error_break to debug";

I searched and set a breakpoint in malloc_error_break to debug, but still cannot find the problem. I tried to changed the scheme of project, enabled Zombie Object, but can not find the answer.

I also try to use instrument, but I am not good at it.

Solution 1

I've fixed this error with Xcode 8 on iOS 8.3. I've just changed Deployment Target from 8.3 to 8.0. If the error appears now after migration to Xcode 8 and your device works under control iOS 8 it may be temporary decision.

UPD: Xcode 8.1 beta is fixed this error.

Solution 2

Just fixed this same issue with Xcode 8. Preparing an iOS10 compatible build, updated to recommended Swift Migration 2.3, runs perfectly on iOS9 and iOS10 but crashes on iOS8.4. I reverted the changes in the code and the Main.storyboard and built the same content on the iOS8 with Xcode 7.3 fixed my issues.

This is it! Lowering the deployment target to iOS 8.2 also works. Here is more related info: stackoverflow.com/questions/39735353/…

My deployment target is 9.3 ... is that still relevant?

@NathanH, for Deployment Target 9.3 and later it's not relevant. Also as and with Xcode 8.1+, for example Xcode 8.3.3.
