Allocations tracking library was not loaded in time and unable to see stack trace

Question

For opening Instruments we must profile first then select which template we have to profile memory leaks,allocations,zombies. But still I get the error allocations library was not loaded, and could not see the stack trace also. And could not find the reason of leak in the application

As mentioned solution in other links, I am using both simulator (iOS7), and active scheme (iOS7)

Xcode Version:Version 5.0.2 (5A3005) Simulator: iOS 7.0.3 (111B508) Mac: OS X Version 10.8.5

Please excuse if any information above is incorrect. Please give answers..Thanks in advance

Answer 1

I'm running into the issue on iOS 7 simulator. I still don’t know how to fix this, but I may have found a workaround.

1. Tap on “Record button” to stop the instrument if it’s running.
2. Select Instrument -> Delete ‘Allocations’ Instrument… menu. You can see only ‘Leaks’ in the Instruments
3. Tap on “Record button” to star the instrument. Start your application on the simulator.
4. Tap on Library button and drag “Allocations” onto Instruments. You can see 'Leaks' and "Allocations" in the Instruments

I can see the stack trace after Step 4.

Answer 2

In my case it only works using the iOS simulator version 8.1 +.

Also, don't forget to change to 8.1 in the project Build Settings under iOS Deployment Target

Answer 3

I experienced this in Xcode 8.3 and it was caused by Build Configuration mismatch for Run and Profile.

Profiler tried to run Release type of application which was not even built.

So it caused the error.

After changing Profile Build Configuration to product type that was already built, in my case Debug, it resolved the issue and Instruments worked again.
