automation - Appium [iOS] Instruments crashed on startup

Question

Maybe somebody can help me.

When appium tries to run application, the screen flashes with app splash screen, as if appium tries to launch app multiple times. This behaviour happens both on simulator and real device.

I set enable on my iOS devices UI Autimation, but when i try start inspector i have this problem:

Target failed to run: Permission to debug com.myapp.iphone was denied. 
The app must be signed with a development identity (e.g. iOS Developer).

You application should be signed with developers key. Click here for documentation
