Nothing? FTA: “The downside to calling mach_absolute_time directly, though, is that it’s on Apple’s “naughty” list – apparently it’s been abused for device fingerprinting, so Apple require you to beg for special permission if you want to use it”

I'm pretty sure I can trigger a hit to the naughty API just by updating a @Published var in an ObservedObject. For those unfamiliar with SwiftUI, this is the most basic way to tell the system that your model data has changed and thus it needs to re-render the view. Pretty much every non-trivial SwiftUI app will need to do this.
