Hi guys. First of all, this is really good. I stumbled onto this project while trying to write a custom symbolicator for MetricKit CrashDiagnostics, and your samply-symbols crate is best-in-class. Overall, super easy to read, extend, and work with overall.

Ok, now my issue is I am working on an XCode app for macOS. Think standard, UI app with swiftUI and the whole setup. It's very reliant on xcode or at least xcodebuild to build. How can I build this app in a way that samply can profile it. When I perform a standard debug build, and then run samply with samply record path/to/MyApp.app/Contents/MacOS/MyApp, I get this log

> samply record /Applications/Roam.app/Contents/MacOS/Roam
^CUnexpected Shutdown message for root task?
Profiling failed: Could not obtain the root task.

On macOS, samply cannot profile system commands, such as the sleep command or system python. This is because system executables are signed in such a way that they block the DYLD_INSERT_LIBRARIES environment variable, which subverts samply's attempt to siphon out the mach task port of the process.

Suggested remedy: You can profile any binaries that you've compiled yourself, or which are unsigned or locally-signed, such as anything installed by cargo install or by Homebrew.

Now the app runs fine under samply, but it no sampling is shown when I press Ctrl-C and stop samply.
