Why isn't Xcode showing test coverage?
swift, xcode, xcode8
Solution
Works fine on my machine:
Don't forget to choose Editor > Show Code Coverage (you didn't mention that in your little checklist).
Problem
Using Xcode 8.2.1 A suite of Swift XCT unit tests isn't highlighting code coverage (with green/red highlighting and numbering) on the corresponding swift file when run. - I have ticked `code coverage : Gather coverage data` in the test scheme. - I have tried deleting `~/Library/Developer/Xcode/DerivedData` and `~/Library/com.apple.dt.Xcode`, in finder. - I have tried quitting simulator and running again. - I have tried running all tests with cmd ⌘ + U, the diamond in the test class, and individual tests. - All tests are passing I know the report navigator can show coverage but it is in a detached way.
