TODO:
Have you ever got the error message "App installation failed: Could not inspect application package" when you try to deploy your swift app to your iPhone?
SOLUTION:
There are many causes but what my issue was was this. I had an info.plist file specified in the "Copy Bundle Resources" section in "Build Phases". Once I removed that, my app installed.
There are also a series of other solutions at this site that may help if you do not have the issue above.
NOTES:
The app would work in the Simulator just not install to the iPhone
