Xcode 8.3.2 : Could not hardlink copy

Question

I am getting this error message while trying to launch my app in simulator. What is the actual issue?

Answer 1

Do below steps,

1. Clean Build
2. Delete Derived Data
3. Simulator (Reset Content and Settings)
4. Quit Xcode & Run Again

Answer 2

The apps installed in the simulator could have become inconsistent.

Resetting the Content and Settings will solve the issue.

Also try to clear Derived Data then clean and build the project.

Answer 3

In my case the Build number was wrong. So in the Info.plist the Build number disappeared, it was blank.

To fix this, I had to re-enter the build number. Delete the app from the simulator Then when I built the app it installed again on the Simulator and started to work fine in subsequent builds as well.
