Firebase logging garbage into console. Xcode - 8 (Swift3)

Question

This below is the code I used. Can anyone help me to solve this problem?

AppDelegate.swift

import UIKit
import CoreData
import Firebase

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {

var window: UIWindow?


func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
    // Override point for customization after application launch.

    FIRApp.configure()

    return true
}

....
}

ViewController.swift

import UIKit
import Firebase

class ViewController: UIViewController {


@IBOutlet var Username: UITextField!

@IBOutlet var Password: UITextField!

override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view, typically from a nib.
}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.
}


@IBAction func CreateAccount(_ sender: AnyObject) {

    FIRAuth.auth()?.createUser(withEmail: Username.text!, password: Password.text!, completion: {
        user, error in

        if error != nil{
            self.login()

        }
        else{
            print("User Created")
            self.login()
        }


    })
}

func login(){

    FIRAuth.auth()?.createUser(withEmail: Username.text!, password: Password.text!, completion: {
        user, error in

        if error != nil{
            print("Incorrect")

        }
        else{
            print("OK")

        }


    })


}


}

Answer 1

Just add OS_ACTIVITY_MODE to disable in your edit scheme Environment Varibale:-

Product -> Scheme -> Edit Scheme -> Run -> Arguments -> Environment Varibales ->

Click on the add button and add this key value pair to it:-

OS_ACTIVITY_MODE : disable

PS:- You also might wanna enable your keychain sharing capabities for your app. And check if your appName.entitlements has conformed to those changes.

P.P.S:- Also try running pod update , given Xcode8 GM just released , Firebase is most probably gonna fix these bugs in future updates.:- Firebase Blog
