Important to note for Firebase Realtime Database that their funcs are builtin to execute on background thread and completion handlers automatically return on the main thread. Thanks for all your videos!

I've been hunting for weeks, I'm hoping you can help. I want a UILabel on my main ViewController to update with the new .text value as the function is progressing. I can not find anyway to push a view refresh or whatever works?

“I don’t know why they’re redundant here…”

It’s because Apple moved those constants from an old class. The ones that are struck through are the old, deprecated ones.

Great videos. Can you make a video about how to read the Apple Documentation? I always find it hard to find the critical information about for example a function or other thing.
