"dyld: could not load inserted library '/usr/lib/libgmalloc.dylib' because image not found"

Question

When I run the app in Xcode IOS 6 beta 2 firmware on the device 8 Beta 2, I get the error message: "dyld: could not load inserted library '/ USR / Library / libgmalloc.dylib", because the image was not found. "

What could be the problem?

Disable "Enable guard Malloc" from diagnostics to run app in device.

this worked for me, in ios 10.3, swift 3.1 and xcode 8.3 – Julio_oa Apr 19 '17 at 00:47
Hm, but I actually enabled this myself to guard malloc on the device, and then started getting this error. So, I guess no luck, cannot fully debug on real device which is a shame because I need to debug my Bluetooth code, which is not available in emulator. – JustAMartin May 25 '17 at 14:30
Works for me, in iOS 13, Swift 5.1 and Xcode 11. And for those wondering where `Guard Malloc` is: Click on the current scheme > Edit Scheme > Run tab > Diagnostics > `Guard Malloc` checkbox – wzso Mar 26 '20 at 02:39

This is because Xcode mount wrong DeveloperImage. If you open the Settings-> Developer you will see that the "Enable UIAutomation» and others are missing.

For fix:

move all folders from "/Applications/Xcode6-Beta2.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport" except "8.0 (12A4297e)" to safe place
reboot the phone
connect your phone to xCode 6 beta 2
restore folders in DeviceSupport

This is the only thing that helped me. Even re-flashing on ios8 beta2 does not helps.

Modifying the contents of Xcode itself is nearly always the wrong thing to do. I wouldn't recommend doing that. – clarkcox3 Jul 03 '14 at 22:50
I did not have to copy any folders anywhere, but rebooting the phone was mandatory. This helped, thanks! – Legoless Jul 28 '14 at 07:46
Here is a theory why this happens: https://devforums.apple.com/message/1000609#1000609 – hashier Aug 05 '14 at 08:40
This actually worked for me on Xcode 9 beta 4, thanks! – EdwardSanchez Aug 03 '17 at 16:58

If you're using any 3rd party IDEs for iOS development (e.g. RubyMotion) you should be able to fix this by rebooting your device without that 3rd party IDE running and building and running an app on your device from Xcode.

I've been seeing this on Xcode 7.1. My quick and dirty solution has been to open the right sidebar of the playground, and toggle the platform setting under "Playground Settings".

In my case, I toggled from iOS to OS X and viola, playground compiles and runs as expected.

Reboots had no effect in my case.

Disable "Enable guard Malloc" from diagnostics to run app in device. Edit Scheme step - 1

Step 2: you can see Memory Management Uncheck Guard Malloc

Try deleting the app from the device and then reboot. Worked for me.
