Using Firebase push() to create a list - ios

Question

Here is the reference I created to my Firebase database
let ref = FIRDatabase.database().reference()
However, when I try to use this as the base_url for a push(), I get this error:
Value of type 'FIRDatabaseReference' has no member 'push'
I tried to change my base_url to this:
let ref = Firebase.database().ref()
But then I get
Module 'Firebase' has no member 'database'
Here's my Podfile. Am I missing something? I have imported Firebase at the top of my file.
# Uncomment this line to define a global platform for your project
# platform :ios, '9.0'
target 'ValleybrookMessenger' do
# Comment this line if you're not using Swift and don't want to use dynamic frameworks
use_frameworks!
# Pods for ValleybrookMessenger
pod 'Firebase'
pod 'Firebase/Database'
pod 'Firebase/Auth'
target 'ValleybrookMessengerTests' do
inherit! :search_paths
# Pods for testing
end
target 'ValleybrookMessengerUITests' do
inherit! :search_paths
# Pods for testing
end
end

Answer 1

Swift doesn't have a push() method, so the equivalent you probably want is childByAutoId().
The first way you created the reference is correct:
let ref = FIRDatabase.database().reference()

Answer 2

Swift doesn't provide push method as javascript does, but you can perform similar action by following code
let ref = Database.database().reference("Items")
var key = ref.childByAutoId().key as? String ?? ""
ref.child(key).setValue(["Item_Name" : name])
In javascript push method automatically generates a unique key but in swift you can generate by
var key = ref.childByAutoId().key as? String ?? ""
which you can add to reference as a child and setValue inside that key.
