问题
When I open "Instruments" application and try choose any template for my simulator (Time Profiler or any other) I get "Import Trace" window with all possible tracetemplates files from '/Applications/Xcode.app/Contents/Applications/Instruments.app/Contents/Resources/templates' directory. Then I choose any one and after it I get alert message 'The document “Time Profiler.tracetemplate” could not be opened.' But in command line instruments works correct. How can I find reasons of such behaviour?
Also from console application logs I get: "appleeventsd(62) deny file-read-metadata /Library"

Found a solution in the new Apple Developer Forums.
Run this from a terminal:
sudo chmod a+rwxt /Library/Caches/com.apple.dt.instruments
