Today i tried to integrate facebook SDK to my Swift app but in the quick start on facebook guide page looks a bit different than my old code. How can i convert OBJ-C code be

Answer 1

I know this is a pretty old question here but it seams that it will never be outdated as Facebook hasn't updated their QuickStart guide for a long time.

So here is the solution for Swift 4.x.

In didFinishLaunching:

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {

    FBSDKApplicationDelegate.sharedInstance()?.application(application, didFinishLaunchingWithOptions: launchOptions)

    return true
}

In open Url:

func application(_ app: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey : Any] = [:]) -> Bool {

    let handled = FBSDKApplicationDelegate.sharedInstance().application(app, open: url, sourceApplication: options[.sourceApplication] as? String, annotation: options[.annotation])
    return handled
}
