Twice now I have gotten into a state where code coverage is shading all my source code and numbers in the right-hand gutter are all zero.
In viewing the reports though, I do see proper data there for each source file (various percentages of coverage).
I have tried the following to no avail:
* Toggle the code-coverage display settings on/off
* Uncheck code coverage generation (target settings), then turn back on
* Closed/re-opened the project
* Clean build
* Quit Xcode
* Deleted all Derived Data and other cached files
This has happened with both Beta 1 and now with Beta 2.
Eventually, the results did come back (though haven't come back yet this last time). I have no idea though what is resetting things or what causes the issue in the first place.
Projects are very simple Swift standalone apps (no static libraries, frameworks).
Anyone else seeing something like this?
