ios - Getting all data in a Firebase column -


i created json database tree , can read specific values these codes. can see on table view "albert einstein"

ref.child("personel").child("name").observesingleevent(of: .value, with: { (snapshot) in              if let item = snapshot.value as? string{                  self.mylist.append(item)                 self.lessonstableview.reloaddata()             }          })

but, want see categories under personal column? this,

is there way or learn columns under "personal"

table view output must -> age, name, photo

you can iterate on snapshot, it's children , childrens keys

say have users node user

users   user_0     fav_game: "wow"     name: "leroy"

then keys of name: , fav_game:

let userref = self.ref.child("users").child("user_0") userref.observesingleevent(of: .value, with: { snapshot in     child in snapshot.children {         let snap = child as! datasnapshot         let key = snap.key         print(key)     } })

prints

fav_game name

an important note is

for child in snapshot.children

because keep data (keys in case) in order. if snapshot dumped dictionary looses order.
