Question

App installation failed

c

Answer 1

My issue was an embedded framework.

Go to "Build Phases" -> "Embed Frameworks" -> Check "Copy only when installing", and it got rid of the issue for me.

Answer 2

I was having the same error, i just deleted the project and fixed!

Go to Window -> Project and right click, and remove from projects!

Answer 3

One reason this can happen is if your app bundle contains broken symlinks.

Answer 4

For me the following did not work on iOS 11 beta 10, XCode 9 beta 6:

• Restart the device
• Deleting the app from the device
• No symlinks were in the project
• There was plenty of storage available

Deleted Derived Data and voilá, it worked again

Answer 5

In the case of your device have an app with the same bundle identifier, Xcode will throw this error. Try to delete potential app with the same bundle identifier.

Answer 6

Also this the error shown if your machine running Xcode is low on space.
