Hello,
I see the Instruments app has gotten a nice upgrade for Xcode 16. There is one issue left that has been bothering me though.
If my app is installed inside the "Application" folder, and I then try to launch Instruments for a new build of the same app from within XCode, Instruments will run the app installed in "Applications" instead of running the app I just built.
The problem with this, is that it's very easy to accidentally profile an old version of your app, and come to the wrong conclusions.
I've created a video showing this issue: https://youtu.be/IloFsQQFgSw
Thank you for reaching out to the forums.
It seems like a Instruments on the Xcode 16 beta is selecting the wrong app to profile, based on your video.
