Xcode 7.1 : Simulator can't be opened because the identity of developer cannot be confirmed

Question

I've upgraded my Mac OS X to 10.11.1 El Capitan. When I try to run app on Xcode 7.1 I'm getting an pop message stating "Simulator" can't be opened because the identity of the developer cannot be confirmed. Refer screenshot.

Why this message? I'm not able to test any app on Xcode 7.1.

Answer 1

Apple believes is security that's the reason only apps which you have downloaded from App Store can be opened.

Well, to open any app which you have downloaded and install from anywhere you need to allow permission. To do so:

1. Open 'System Preferences'
2. Go to 'Security & Privacy' and tap on 'General' tab
3. Click on 'Lock' icon which you can find on bottom left screen and type your administrator password.
4. The last step is to choose 'Anywhere' under 'Allow apps downloaded from:' and then again click on 'Lock' icon.
5. That's it. Now you can run any apps.

Enjoy!
