No matter which project I start profiling, it will always, automatically, profile it with the profiler "All Heap & Anonymous VM" only (It doesn't give me the chance to choose between the instruments). Also it's not possible to run after adding a new profiler, the app will just crash immediately without any error. Is this some kind of known issue?

Is there any way to reset Xcode instruments? I am using the latest version of Xcode.

EDIT: It seems like it is possible to add new profilers and run them successfully, it's just not possible with the Time Profiler tool.

Look at the Profile action in the scheme editor for whichever scheme you are profiling with. The "Info" tab has an "Instrument" setting that should be set to "Ask on Launch" if you want to be able to select a different template when Instruments is launched by Xcode.

As for your crash, please file a radar with more precise reproduction steps, device info, etc... If you can include the crash report for the app as well, that might prove useful.
