SaveImagetoFirebase.swift

      var data: NSData = NSData()
 
        if let image = photoImageView.image {
           data = UIImageJPEGRepresentation(image,0.1)!
        }

        let user: NSDictionary = ["name":name!,"dob":dateOfBirthTimeInterval, "photoBase64":base64String]
 
        //add firebase child node
        let profile = firebase.ref.childByAppendingPath(name!)
 
        // Write data to Firebase
        profile.setValue(user)
        
        
        
ref.observeEventType(.Value, withBlock: { snapshot in 
    self.base64String = snapshot.value as String
    let decodedData = NSData(base64EncodedString: base64String, options: NSDataBase64DecodingOptions.IgnoreUnknownCharacters)

                imageView.image = decodedImage
