Can't deploy app to ios 8 device

Question

Just updated an iPad Mini to iOS 8 and suddenly can't debug my app on it with XCode 6.0.1. The error in Xcode is App installation failed with An unknown error has occurred.. On the device the app remains greyed out.

Tried to :

• delete the app from ipad ( was working before )
• Soft reset and reboot the device
• Delete derived data and clean
• Reboot the mac
• reinstall xcode
• change the bundle id and product name
• Recreate the dev certificates and provisioning profiles

With iOS 6 and iOS 7 devices works fine, also, can debug other projects too, but not this one, so I'm getting desperate.

Any idea ?

Edit:

It seems that the regeneration of the certificates was the solution but after Clean there was necessary a Clean Build Folder too, which solved the issue (for now at least).

Answer 1

Just to add (and thanks to everyone for the hints given here) that systematically finding out the cause of this was key for me resolving this.

Using the “Devices” Window in Xcode6 to then connect to the plugged in iPhone allows you to view the live log - once you have selected the iPhone click on the tiny up-arrow icon at the bottom. In my case the output was as shown below, strongly indicating that “Failed to verify code signature…” of one of my (custom) bundled frameworks was at the crux of the problem.

This lead me to check and find out it was nothing to do with out of date certificates (everything was in date) nor any left-over DerivedData or temp build files (although always good to do a clean!)

It was the fact that my custom framework’s “CFBundleExecutable” had a typo - so signing was actually throwing an error. This is not immediately reported in Xcode - even if the tick box is on for your embedded frameworks to "Code sign on copy". Try signing a framework separately on the command line and it will tell you!

Answer 2

I just got hit by this with Xcode 7.2. Looking at the device console log pointed to a 3rd party framework in CocoaPods. Did a "pod update" and all is good now.
