Memory profiling a Rust binary with XCode 13.2.1

Question

With an earlier version of Xcode, I was able to profile my Rust binaries' allocations following these instructions. It worked beautifully. https://developer.apple.com/library/archive/technotes/tn2434/_index.html

Now, I'm using version 13.2.1, and Xcode shows me empty windows.

I set up the profiling session like this:

Then, I click the run button. The Debugging Session panel lights up for a second or two, then my process exits and I'm left looking at the following. I don't see allocations profile information or a button to click to show it to me.

I tried using Release and Debug binaries, and the result is the same.

Answer 1

I found the old "Instruments."

Just skip the tools in Xcode.
