私は公式Firebase YouTubeアカウント(https://www.youtube.com/watch?v=joVi3thZOqc)のチュートリアル以下だったが、私はこの単純なアプリを取得するためにマニュアルを読み、変更のカップルを適用しなければならなかったので、それは古いseemes正しく機能します。私はAppDelegate.swiftファイルにlldbエラーが表示されます。スウィフトはシンプルなアプリに - lldbエラー
import UIKit
import Firebase
import FirebaseDatabase
@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate { //error here
var window: UIWindow?
override init(){
FIRApp.configure()
}
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
// Override point for customization after application launch.
return true
}
ViewController.swiftファイル:
import UIKit
import Firebase
import FirebaseDatabase
class ViewController: UIViewController {
//FBDataBase variables
var ref: FIRDatabaseReference = FIRDatabase.database().reference() //root directory
//interface variables
@IBOutlet weak var label: UILabel!
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
}
override func viewDidAppear(_ animated: Bool) {
super.viewDidAppear(animated)
ref.observe(.value) { (snapshot) in
self.label.text = snapshot.value as? String
}
}
//interface functions
@IBAction func sunnyPressed(_ sender: Any) {
ref.child("condition").child("addedByUser").setValue("sunny")
}
@IBAction func foggyPressed(_ sender: Any) {
ref.child("condition").child("addedByUser").setValue("foggy")
}
}

私はスウィフトとFirebaseに新たなんだので、私は」をいくつかの助けを得ることを楽しみにしています。修正はおそらく非常に簡単で、スキルの欠如のために何かが欠けているだけです。
おそらくあなたのストーリーボードには、クラスを正しく設定していない可能性があります。 – ctabuyo
ViewController.swiftにViewControllerクラスを設定していないということですか?私はそれを疑う、それはデフォルトで設定され、アプリケーションは、Firebaseを含むコード行のカップルのカップルを適用する前に実行していた – codddeer123
