LGTM! Thanks for doing this!

Looks like Bitrise failed on this.

• instrumentation tests failed, but the failure looks irrelevant to this (probably a test flake)
• screenshot tests failed, because we have some screenshots that need to be updated due to this change. You can update the screenshots by downloading them from the "artifacts" tab in the bitrise test run and then moving the new screenshots into your branch -- lmk if I can help with that
