Question

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

It's pretty much the same, except instead of using brackets, you use dots.

func applicationDidBecomeActive(application: UIApplication!) {
    FBSDKAppEvents.activateApp()
}

func application(application: UIApplication!, didFinishLaunchingWithOptions launchOptions: NSDictionary!) -> Bool {
    return FBSDKApplicationDelegate.sharedInstance().application(application, didFinishLaunchingWithOptions: launchOptions)
}

func application(application: UIApplication, openURL url: NSURL, sourceApplication: String, annotation: AnyObject?) -> Bool {
    return FBSDKApplicationDelegate.sharedInstance().application(application, openURL: url, sourceApplication: sourceApplication, annotation: annotation)
}

Answer 2

This has been depricated in iOS 10.

func application(application: UIApplication, openURL url: NSURL, sourceApplication: String, annotation: AnyObject?) -> Bool {

For Swift 3.0, you can use:

Swift 3.0

func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -> Bool {
    let isHandled = FBSDKApplicationDelegate.sharedInstance().application(app, open: url, sourceApplication: options[.sourceApplication] as! String!, annotation: options[.annotation])
    return isHandled
}

Answer 3

I know this is a pretty old question here but it seams that it will never be outdated as Facebook hasn't updated their QuickStart guide for a long time.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

Answer 4

Swift 5 with FBSDKCoreKit (5.3.0)

Import FBSDKCoreKit in appdelegate

In didFinishLaunching:

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
    FBSDKCoreKit.ApplicationDelegate.shared.application(application, didFinishLaunchingWithOptions: launchOptions)
    return true
}

In open Url:

  func application(_ app: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey : Any] = [:]) -> Bool {
    let handled = FBSDKCoreKit.ApplicationDelegate.shared.application(app, open: url, options: options)
    return handled
}

Answer 5

Since I want to support iOS 8, I have modified the function application(_:open:options:) in Whitney Foster's answer to

func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -> Bool {
    let appId = SDKSettings.appId
    if url.scheme != nil && url.scheme!.hasPrefix("fb\(appId)") && url.host ==  "authorize" { // facebook
        if #available(iOS 9.0, *) {
            return SDKApplicationDelegate.shared.application(app, open: url, options: options)
        }
    }
    return false
}

and implemented additional fallback function

// Fallback on earlier versions
func application(_ application: UIApplication, open url: URL, sourceApplication: String?, annotation: Any) -> Bool {
    return SDKApplicationDelegate.shared.application(application, open: url, sourceApplication: sourceApplication, annotation: annotation)
}
