This can have several causes. The fastest way to figure out what is causing it is to go into Xcode, Window menu, Devices, then click the reveal button at the bottom of the pane to show the Console. Now attempt to run. You should see log output that names the specific files it is complaining about.

Most of the solutions previously posted are just artificial ways of getting Xcode to regenerate the contents of the build folder and/or re-sign the files.

In my case, my WatchKit extension was somehow acquiring references to Cocoapods frameworks that were only targeted toward the main app so they got signed during the build, then pruned later (as they were not used). Then on device, iOS complained that they were missing from the .appex folder for the extension. I ended up not needing any pods in the extension so I just removed them all and removed the extension as a target, then did some minor cleanup to remove the pod-related debris left in the build steps. Now everything works perfectly.
