var loggedInUser: User?
let storageRef = Storage.storage().reference()
let databaseRef = Database.database().reference()
// structure definition goes here
override func viewDidLoad() {
super.viewDidLoad()
self.loggedInUser = Auth.auth()?.currentUser//Cannot use optional chaining on non-optional value of type 'Auth'
self.databaseRef.child("user_profiles").child(self.loggedInUser!.uid).observeSingleEventOfType(.Value) { (snapshot:DataSnapshot) in //'observeSingleEventOfType(_:withBlock:)' has been renamed to 'observeSingleEvent(of:with:)'
self.name.text = snapshot.value!["name"] as? String//Type 'Any' has no subscript members
self.handle.text = snapshot.value!["handle"] as? String//Type 'Any' has no subscript members
//initially the user will not have an about data
if(snapshot.value!["about"] !== nil)
{
self.about.text = snapshot.value!["about"] as? String
}
if(snapshot.value!["profile_pic"] !== nil)//Type 'Any' has no subscript members
{
let databaseProfilePic = snapshot.value!["profile_pic"]
as! String//Type 'Any' has no subscript members
let data = NSData(contentsOfURL: NSURL(string: databaseProfilePic)!)
self.setProfilePicture(self.profilePicture,imageToSet:UIImage(data:data!)!)
}
//self.imageLoader.stopAnimating()
}
// Do any additional setup after loading the view.
}
var loggedInUser = AnyObject?()//this code was giving me an error
//Cannot invoke initializer for type 'AnyObject?' with no arguments
Then I switched it to:
var loggedInUser: User?// still giving me errors
Replace Auth.auth()?.currentUser
with Auth.auth().currentUser
.
auth()
returns a non-optional type, so you can't use optional chaining with it.
Take a look at its documentation , it returns an object of type Auth
not Auth?
.
1- You should declare the user like
var loggedInUser: FIRUser?
Then assign it in viewDidLoad
loggedInUser = Auth.auth().currentUser
2- snapshat.value
is of type Any
so you need
let value = snapshot.value as! [String:Any] // you can do [String:String] if all values are strings
self.name.text = value["name"] as! String
self.handle.text = value["handle"] as! String
3- Don't use NS
( use Data
instead NSData
) stuff and avoid contentsOfURL
let data = NSData(contentsOfURL: NSURL(string: databaseProfilePic)!)
in loading remote urls as it blocks the main thread consider using SDWebImage
