I can't run program in ios simulator

[Trikrista]

During startup program warning appears:

Starting remote process.
Session could not be started: Installation FailedUnable to remove simlink at `/Users/mac/Library/Developer/CoreSimulator/Devices/1292C817-FBC9-4582-9E78-3D8ECDAF2727/data/var/folders/sd/3sdbf3757sdd6hh9x3q8tn080000gn/T/ios-sim-stderr-pipe-1469210232'Unable to remove simlink at `/Users/mac/Library/Developer/CoreSimulator/Devices/1292C817-FBC9-4582-9E78-3D8ECDAF2727/data/var/folders/sd/3sdbf3757sdd6hh9x3q8tn080000gn/T/ios-sim-stdout-pipe-1469210232'Run ended.

I use Qt 5.6.1, Xcode 7.3.1
How to fix it?
