I just got started with using Firebase Database for iOS. I fully set up firebase for my iOS with cocoaPods. However, the text doesn't show text retrieved from the database. It just appears empty after being run. What am I getting wrong?

Screenshot of my Database

class AppreciationViewController: UIViewController 
 var ref: DatabaseReference!
 @IBOutlet weak var otherAppreciation: UILabel!
 @IBOutlet weak var support: UILabel!
 @IBOutlet weak var body: UILabel!
 @IBOutlet weak var contact: UILabel!
 @IBOutlet weak var body2: UILabel!
 @IBOutlet weak var dedication: UILabel!

 override func viewDidLoad() 
 super.viewDidLoad()
 ref = Database.database().reference(); ref.child("Appreciation").child("body2").observe(.value) (snapshot) in
 let body2String = snapshot.value as? String
 self.body2.text = body2String
 
 ref.child("Appreciation").child("contact").observe(.value) (snapshot) in
 let contactString = snapshot.value as? String
 self.contact.text = contactString
 
ref.child("Appreciation").child("dedication").observe(.value) (snapshot) in
 let dedicationString = snapshot.value as? String
 self.dedication.text = dedicationString
 
 ref.child("Appreciation").child("otherAppreciation").observe(.value) (snapshot) in
 let otherAppreciationString = snapshot.value as? String
 self.otherAppreciation.text = otherAppreciationString

 
 ref.child("Appreciation").child("body").observe(.value) (snapshot) in
 let bodyString = snapshot.value as? String
 self.body.text = bodyString
 
 ref.child("Appreciation").child("support").observe(.value) (snapshot) in
 let supportString = snapshot.value as? String
 self.support.text = supportString

  Debug! For example you are saying let body2String = snapshot.value as? String. Well, that might be nil. If it is, you won't see any text. Set some breakpoints or add some print statements and figure out what the problem really is.
