ios - Fetch all users from Firebase with Facebook login

my app using facebook login @ moment. trying build search function using uisearchbar.

so question is: in way possible fetch users firebase database array? maybe userid well??

if want see piece of code let me know, did not think relevant question :-)

if have understood you're trying achieve should able save users realtime database upon registering/authenitcating users.

after can perform simple observesingleeventof users @ correct path, this:

rootref.usersref.observesingleevent(oftype: .value).....

then completion handler should snapshot, snapshot.value include users.

*please note don't need stop observing method since observe values once stop. don't think need worry memory issues.
