Swift Firebase How do I add a custom branch to my user? - ios

Question

I am trying to add a custom branch that lists all friends for a user. Currently, I have the code to add a user's email and name (see user1 in the photo below).
let ref = Database.database().reference(fromURL: FIREBASE_GAME)
let usersReference = ref.child("users").child(uid)
let values = ["name" : name, "email" : email]
usersReference.updateChildValues(values, withCompletionBlock: { (err, ref) in
if(err != nil) {
print(err!)
return
}
Would I add "friends" as a key in my values dictionary and then let the value be a sub-branch? I don't know what that would look like in code. I made user2 manually in Firebase (this is what I want to do in code). I'm new to Firebase and most resources give very basic examples. I would appreciate any help.

Answer 1

I think you're looking for this:
let values = ["name" : name, "email" : email, "friends": [ "jake": false, "mike": true ]]
usersReference.updateChildValues(values, withCompletionBlock: { (err, ref) in
if(err != nil) {
print(err!)
return
}
Alternatively, you can write/update the friends with a separate call:
usersReference.child("friends").updateChildValues(["jake": false, "mike": true])

Create a Model Class in Below Format. You need to change the object Friend in your Firebase Console.
class ListModel: NSObject {
var UID:String?
var Name:String?
var Email:String?
var Friends:[Friend]?
}
class Friend : NSObject {
var Name : String?
var Status : Bool?
}
In Your View Controller you can access using below Code
var Obj : ListModel?
var ListArr = [ListModel]()
let ref = Database.database().reference().child(“users”)
ref.observe(.childAdded, with: { (snapshot) in
print(snapshot)
guard let dictionary = snapshot.value as? [String : AnyObject]
else {
return
}
let Obj = ListModel()
Obj.UID = snapshot.key
Obj.Name = dictionary["name"] as? String
Obj.Email = dictionary["email"] as? String
let friendsArr = dictionary[“friends”] as? NSArray
var friendObj = [Friend]()
if friendsArr != nil{
for dict in friendsArr as! [[String: AnyObject]] {
let friend = Friend)
friend.Name = dict["name"] as? String
friend.Status = dict["mobile"] as? Bool
friendObj.append(friend)
}
}
Obj. friendsArr = friendObj
self.ListArr.append(Obj)
}, withCancel: nil)
