Solved: Added Flurry Config Observer in Swift

Today, I added FlurryConfig on AppDelegate.swift, and added the Flurry Config Delegate methods on the AppDelegate like below:

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool { 
    ... 
    FConfig.sharedInstance().registerObserver(self, executionQueue: DispatchQueue(label: "dispatch_queue_#1", qos: .background)) 
    FConfig.sharedInstance().fetch() 
    ... 
} 
 
 
//MARK: - Flurry Config Delegate 
extension AppDelegate { 
    func fetchComplete() { 
        print("FConfig: fetchComplete") 
    } 
 
    func fetchCompleteNoChange() { 
        print("FConfig: fetchCompleteNoChange") 
    } 
 
    func fetchFail() { 
        print("FConfig: fetchFail") 
    } 
 
    func activationComplete() { 
        print("FConfig: activationComplete") 
    } 
}

With the above code, the delegate functions were not invoked, and finally, we find that we need add the @objc to the delegate functions, so the final Flurry Config Delegate functions are like below:

//MARK: - Flurry Config Delegate 
extension AppDelegate { 
    @objc func fetchComplete() { 
        print("FConfig: fetchComplete") 
    } 
 
    @objc func fetchCompleteNoChange() { 
        print("FConfig: fetchCompleteNoChange") 
    } 
 
    @objc func fetchFail() { 
        print("FConfig: fetchFail") 
    } 
 
    @objc func activationComplete() { 
        print("FConfig: activationComplete") 
    } 
}

With the above changes, the delegate methods can be invoked.
