Xcode9 code coverage is not displayed

问题:

I have been trying to get the code coverage for my project using Xcode 9. All test case run successfully but did not generate the code coverage report under Code coverage tab.

I tried following things:

1. Enable the Gather code coverage in scheme.
2. Enable Code Coverage Support for my target.

3. Enable the Show case bundle option.

   Is there extra setting require to check code coverage report ? or should I missed something ? Thanks in advance.

If you want to see the code coverage in the right side of the editor, make sure you have Show Code Coverage selected in the Editor drop down menu.

There was known bug on Apple side addressed missed code coverage for UI tests targets (https://openradar.appspot.com/24006783).

Xcode Version 9.3 beta (9Q98q) seems resolves issue as long as Debug executable not enabled in Test schema.

In Xcode build scheme editor Test -> Info tab -> Debugger make sure that checkbox Debug executable is unchecked.

Here is an example project for Bugreport #24006783: https://github.com/vgorloff/Radar24006783

I'm pretty sure they just moved the code coverage to a new location. I'm seeing it now as part of the report navigator (see screenshot below).

To get there, first turn on code coverage support (edit scheme -> test -> options -> check code coverage box) then look on the left hand side of xcode at the navigator. At the top you will see a bunch of icons. Click on the last one on the right (it looks like a message bubble).

Within that tab, you will see all the tests you ran. Within each test is a "coverage" item. Click on one of those to get the coverage report for that specific test.

If you like me and don't see the Option tab (or any tab) on Target -> Test in your schema, it means you need to add test schema to your app or you select wrong Target.

First select Manage Schemes... and see do you have yourTargetTest and if it is checked or not.

Second, add (small + button) and select your test target.

By the way, if you don't have Test Bundle, please add it to your boundles list first.

Now you will see your test bundle and can select and edit it. And you will see the Options tab, and Code Coverage as mentioned in accepted answer.
