swift scan for all bluetooth devices

I do that but issue is that I can saw only iOS MacBook on list.
I didn’t add any filter to search this but I can’t find the android phone and Bluetooth speaker in list.
So any one know about this please help me out.?
Honestly, I don't know !

But this objc reference may help you: https://stackoverflow.com/questions/37796780/corebluetooth-willrestorestate-what-exactly-should-be-done-there

Effectively doc is very limited here. You could file a feedback report for documentation enhancement.
@Claude31  just last question can we get iPhone bluetooth unique id programatically?
