I'm trying to write performance tests with Xcode 15, but it's not working: even though setting a baseline seems to work (baseline data files are created), Xcode seems to ignore that baseline altogether whenever the test is run. As a result, performance tests never fail, no matter how bad performance gets. The source editor persistently displays a “No baseline average for Time” message. Has anyone else encountered this? Figured out how to sidestep the issue? Of note, the issue is easily reproduced: create a new (macOS in my case) app project with tests, add a dummy performance test; run the test once and save its baseline, and despite this subsequent tests will always succeed, even if you significantly slow the dummy test down. (I've filed this as FB13330139)

The macOS app I'm working on accesses keychain items created by other apps—git remote credentials, likely entered in the Terminal or some other git client. When calling SecItemCopyMatching(), the user is prompted twice in a row: AppName wants to use your confidential information stored in "host.org" in your keychain. AppName wants to access key "host.org" in your keychain. The user needs to enter their login password for each of the two prompts for the access to succeed. Can I consolidate the two prompts into one? The experience with two alerts is somewhat confusing and tedious, compared to what it could be—especially since there is no way of displaying a usage description string in the window, to reassure and provide context.
