I've been using the os.Logger API, but it looks like I need to create an OSLog as well if I want to use the signpost API for tracking performance.

Is that true, or is there some way get an underlying OSLog from a Logger? Then I could write something like:

Code Block swiftextension os.Logger {
    func signpost(...) {
        os_signpost(.begin, ... self.osLog, ...)
    }
}

Correct. Normally I’d suggest that you file an enhancement request for a Swift-y signpost API but in this case I can assure you that the team fully understands this requirement (r. 74617206).

is there some way get an underlying OSLog from a Logger?

There is not. There is a way to construct a Logger from an OSLog, namely Logger(_:), but I don’t think that gets you where you want to be.
