Not sure how much this relates to #2, i.e. how much of CoreBluetooth code can translate between macOS and iOS. Also need to provide documentation on what's required for getting bluetooth access working in iOS apps with rust code (info.plist additions, background perms, etc).

I have very little Cocoa experience, and all my iOS has been through not-quite-native libraries/frameworks (Xamarin/React Native/etc), so lots of open questions.
