启动TestFlight构建需要花费几秒钟（App Store应用很好）

Question

NB: This question was originally posted to the Apple Developer Forums (login required).

Problem

I have an iPhone 6 Plus running iOS 8.1.3 (12B466), for the most part it functions as expected. However any apps I install either via TestFlight or build and run on the device with Xcode all take multiple seconds to launch.

The icon will become dark and after 3, 4 or 5(!) seconds the app will launch, occasionally the entire phone will crash during launch. This happends with any app install via TestFlight not just my own apps. Apps installed via the App Store are fine and launch immediately.

I also have an iPhone 6 adn 5S, these launch TestFlight app immediately as expected.

Anybody else having this problem?

Steps taken to resove:

• Reset phone and restored from back up (did not fix)
• Checked the logs (cannot see anything that might be useful)
• Restarted the phone (hundreds of times!!!!)

Other info

The only other thing I have noticed about my iPhone 6 Plus is from within an app calls to UIImagePickerController also take multiple seconds this is true for (at least); my own apps, iMessage, Tweetbot.

Answer 1

Please see the Apple Dev Forum thread for detailed info.

Xcode 6 had trouble showing me all the installed profiles and only has the ability to delete them one at a time. iPhone Configuration Utility no longer works for deleting profiles (on devices running iOS 8+) and/or under Yosemite.

tl;dr

I used Xcode 5.1.1 to remove most of the provisioning profiles and now apps launch instantly!
