App installation failed

Question

In Xcode 6 Beta 5, when I attempt to run my app after building, I receive an error dialog that says:

App installation failed

Could not inspect the application package.

This happens on iOS 8 Beta 5, but not on iOS 7.1.1! I have not tested anything else.

Any ideas for how I can fix this?

Solution 1

I had this problem. Solution is to uninstall the app. Then clean project and then install app.

Solution 2

I solved it by uninstalling(removing) the application from device manually and Run xcode application again. It will work.

Solution 3

Try editing the scheme of app. Set Run and Archive to debug not release. I was able to solve by this process.

Solution 4

I have had this happen to me about 3 times since moving to Beta 5 and Xcode beta 5. I usually navigate to my Organizer and select Projects. Find your project on the left and delete it. Next I close Xcode and restart both my Mac and my Testing Device! Has helped every time!

Solution 5

Deleting the derived data folder worked for me.

Just clean and then build/install works for me with Xcode 9.2
