Using instruments to find memory leaks

Question

I've tried to read almost every decent tutorial in the internet, but still can't understand what is really happening here:

I've "Hide System Libraries" and "Invert the call tree", but I do not understand how to find actual code responsible for for example this leak. Any tips are appreciated. May be I am missing something obvious. I am getting hundreds of leaks, however I am using weak in closures, I do not have classes referencing each other etc. But it looks like I am missing something fundamental.

The problem shown in your screenshot is Instruments can't find your app's debug symbols. Instruments is showing memory addresses instead of function names. You are not going to be able to find the source of your memory leaks in Instruments without function names, even if you invert the call tree and hide system libraries.

Make sure your project is generating debug symbols. Check that the Generate Debug Symbols build setting is set to Yes. If your project is generating debug symbols, Instruments may be unable to find the dSYM file that contains the debug symbols. In Instruments choose Instrument > Call Tree > Locate dSYM. The dSYM is usually in the same directory as the release version's application bundle. The following article has additional information:
