"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?

Answer 1

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:

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

I did not have to copy any folders anywhere, but rebooting the phone was mandatory. This helped, thanks! – Igor

Here is a theory why this happens: devforums.apple.com/message/1000609#1000609 – Pintsize

This actually worked for me on Xcode 9 beta 4, thanks! – Epicure

Answer 2

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

I cannot debug the guard malloc in device? – Blockhouse

Thats y i have answered, disable guard malloc – Geology

this worked for me, in ios 10.3, swift 3.1 and xcode 8.3 – Linton

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. – Intercede

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 – Falito

Answer 3

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 don't use any 3rd party IDEs. – Stokehole

Answer 4

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.
