Xcode process failed to start: Security problem, no problem in emulator, not on physical machine
It took about a week to two weeks to develop an app, yesterday to upgrade the IPhone 5S to the IOS 8 GM system, the upgrade is not a problem, the test app is not a problem, when I removed from the iphone 5S my app, and rebuilt, the following error occurred.

12	Could not launch "My App"process launch failed: Security

So I immediately after using the simulator test again, no problem, the initial reason is the iphone 5S upgrade to the IOS 8 GM system caused, and now very helpless, do not know how to deal with this problem, I just want to test my app on the iphone 5S

Processing methods

If you have a situation where the app is already installed on your phone, you need to click on the icon to indicate if you really want to run it, and choose "yes" to rebuild and run it.
