You can do something like this:

Facebook* facebook = 
   [[Facebook alloc] initWithAppId:@"YOUR_FACEBOOK_APP_ID" andDelegate:self];

NSMutableDictionary* params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
                                       @"My Title", @"title",
                                       @"Come check out my app.",  @"message",
                                       @"FACEBOOK_USER_ID", @"to",
                                       nil]; 

[facebook dialog:@"apprequests" andParams:params andDelegate:self];

To send facebook app invites, you need to first add details of your app here.. https://developers.facebook.com/quickstarts/?platform=app-links-host

In Swift 2.2, XCode 7.3 and FBSDK 4.1

1. import FBSDKShareKit import FBSDKCoreKit import FBSDKLoginKit

2. Add FBSDKAppInviteDialogDelegate with your ViewController class.

   func appInviteDialog(appInviteDialog: FBSDKAppInviteDialog!, didCompleteWithResults results: [NSObject : AnyObject]!) {
       print("Initiation sent")
   
   }
   func appInviteDialog(appInviteDialog: FBSDKAppInviteDialog!, didFailWithError error: NSError!) {
       print("\(error)")
   }
   

3.     let content = FBSDKAppInviteContent();
       content.appLinkURL = NSURL(string: "fb link that you get in above developers facebook url"); //"https:// fb.me/1775107252721102" in my case
       FBSDKAppInviteDialog.showFromViewController(self, withContent: content, delegate: self);
