Facebook SDK Setup - ios

Question

I'm trying to add the Facebook SDK to my app, I've followed every step.
the only problem I have is that the the the code that I need to add to the AppDelegate is in Objective C and I'm using Swift. I don't know how to convert the Objective C code to swift, Can you help me?
This is the code:
- (void)applicationDidBecomeActive:(UIApplication *)application {
[FBSDKAppEvents activateApp];
}
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
return [[FBSDKApplicationDelegate sharedInstance] application:application
didFinishLaunchingWithOptions:launchOptions];
}
- (BOOL)application:(UIApplication *)application
openURL:(NSURL *)url
sourceApplication:(NSString *)sourceApplication
annotation:(id)annotation {
return [[FBSDKApplicationDelegate sharedInstance] application:application
openURL:url
sourceApplication:sourceApplication
annotation:annotation];
}
Thanks!
