I have created a Swift App Project which only has a basic suite for a single-page application. And I add -profile-generate and -profile-coverage-mapping two flags in Build Settings -> Swift Other Flags. However， it has not generated *.profraw or *.profdata file.
Meanwhile, I have created another Command Line App with Xcode, and add the same flags in build settings. Build and Run project, then I got *.profraw I want.
So, what can I do with Swift Single Page App to Generate the *.profraw file?
