I have confirmed that my Firebase project and my Xcode project are linked; I then initialized Firebase in my App.swift file as follows:
@main
struct TRACEApp: App {
init() {
FirebaseApp.configure()
}
...
I then wrote the following lines in ContentView.swift to test the realtime database:
import SwiftUI
import Firebase
var ref: DatabaseReference!
var writeChild: Void {
ref = Database.database().reference()
ref.child(“user_id”).setValue(123456)
return
}
However it fails on that line just before the return call, with the message "Missing argument for parameter #1 in call"
How can I test the realtime database such that it compiles? I wrapped those lines in the var simply because I cannot call functions without assigning them at the top level. Any advice would be much appreciated.
I think the issue in the double quotation that you put around user_id which you use ( ” ) however you should use ( " )
That's why it couldn't read this parameter.
