Xcode process launch failed: Security

Question

I have been developing an app for 1 or 2 weeks now and just yesterday I have updated my iPhone 5S to the iOS 8 GM. Everything worked fine and I could test on my device as we

Answer 1

Hey so the accepted answer works, except if you need to debug the initial launch of the app. However I think that answer is more of a work around, and not an actual solution. From my understanding this message occurs when you have some weirdness in your provisioning profile / cert setup so make extra sure everything is in tip-top shape in that dept. before ramming your head against the wall repeatedly.

What worked for me was as follows from the apple docs:

Provisioning Profiles Known Issue If you have upgraded to the GM seed from other betas you may see your apps crashing due to provisioning profile issues.

Workaround:

1. Connect the device via USB to your Mac

2. Launch Xcode Choose Window ->Devices

3. Right click on the device in left column, choose "Show Provisioning Profiles"

4. Click on the provisioning profile in question

5. Press the "-" button Continue to removing all affected profiles.

6. Re-install the app

Make sure you right click on the image of the device not the name of the device or you won't see the provisioning profiles option. I restored my new phone from an old backup and there was a lot of cruft hanging around, i also had 2 different dev. certs active (not sure why) but i deleted one, made a new profile got rid of all the profiles on device and it worked.

Hope this helps someone else.
