How to add context menu to app in IOS

This is UIMenuController

. I'm not good with Swift. For Swift, please check this link. The purpose of the C code looks like this:

- (void)showMenu
{
    UIMenuController *menu = [UIMenuController sharedMenuController];
    menu.menuItems = @[
       [[UIMenuItem alloc] initWithTitle:@"Title1" action:@selector(MyAction1)],
       [[UIMenuItem alloc] initWithTitle:@"Title2" action:@selector(MyAction2)],
       [[UIMenuItem alloc] initWithTitle:@"Title3" action:@selector(MyAction)]];
    [menu setTargetRect:self.bounds inView:self];
    [menu setMenuVisible:YES animated:YES];
}
