swift 3 firebase current user query

I'm new to firebase i'm trying to retrive current user info, which is username, photo, etc.

Here is the code:

let queryRef = FIRDatabase.database().reference().child("users")


    queryRef.child(FIRAuth.auth()!.currentUser!.uid).observe(.value, with: { (snapshot) -> Void in
        print(snapshot.value as! NSDictionary)
    })

Here is output

{

email = "[email protected]";

gender = male;

nickname = "Sam <3";

username = sam;

uid = 4nyyBF91JhSLY0DhkjfJ0DCDZK03;

urlToImage = "https://firebasestorage...;

}

And how can i print something specific like getting email, username, nickname as String, And photo as uiimage?

You just need to simply use subscript with your Dictionary. Also in Swift use Dictionary instead of NSDictionary.

let queryRef = FIRDatabase.database().reference().child("users")
queryRef.child(FIRAuth.auth()!.currentUser!.uid).observe(.value, with: { (snapshot) -> Void in

    if let dictionary = snapshot.value as? [String:Any] {
        let email = dictionary["email"] as? String ?? ""
        print(email)
        let gender = dictionary["gender"] as? String ?? ""
        print(gender)
        //Access the other key same way.
    }
})
