I just updated to Xcode 7.3.1 and my project crashes with the same error after the launch screen displays on the iOS simulator.
The error is:
"Could not attach to pid : “1712” unable to attach"
Then I tried running another project and I got:
"Could not attach to pid : “2025” unable to attach"
Any solutions?

To view your project's current schemes, click the scheme name in the toolbar of your project window. Xcode displays a pop-up menu with a list of current schemes at the top, and commands to edit, create, and manage schemes at the bottom. To view and modify your project's current schemes, select Manage Schemes.
Resetting the content and settings in the simulator worked for me. This is available on the iOS Simulator: Hardware -> Erase all Content and Settings
Kill the simulator, then re-build.
