I faced the same problem. So, I downloaded the latest SDK and found that App Invites are no longer supported from Facebook SDK version 4.28 and above. I downloaded the latest SDK version 4.33.0 from developers site and when I opened FBSDKAppInviteDialog class and found that the below methods are deprecated and are written as below.

+ (instancetype)showFromViewController:(UIViewController *)viewController
                           withContent:(FBSDKAppInviteContent *)content
                              delegate:(id<FBSDKAppInviteDialogDelegate>)delegate
__attribute__ ((deprecated("App Invites no longer supported")));


/**

 - Warning:use showFromViewController:withContent:delegate: instead
 */
+ (instancetype)showWithContent:(FBSDKAppInviteContent *)content delegate:(id<FBSDKAppInviteDialogDelegate>)delegate
__attribute__ ((deprecated("use showFromViewController:withContent:delegate: instead")));
