set baseline performance test in Xcode 9

I have the latest verion: 9.1 (9B55) running on 10.12.6 (16G1036)

In the Report Navigator, select a test run on the left, then select the Tests tab in the editor, then click the Set Baselines button at the top.

Thanks for the answer. I never used the Report Navogator before.

Unsing the "Set Baselines" button indeed works as expected. It is a bit cumbersome to update a test as Xcode switches to the Issues Navigator all the time.

I managed to get to the popup a few times (not sure how). But setting the baseline there is broken, it always sets it to zero so you get a "inf% worse" the next time you test.

I’m not sure exactly what issue you’re hitting but in most cases like this you can tweak the default behaviour in Xcode > Preferences > Behaviours.

Weird. Both of these issues (inability to access the popup and the zero problem) sound bugworthy.
