I am trying to get a UIActivityViewController for presenting only the options for Facebook, Twitter and Instagram. So far I have done:

 let shareText = "Hello, world!"

 let image = UIImage(named: "TheImage")
 let activityViewController = UIActivityViewController(activityItems: [shareText,image], applicationActivities: nil)
 activityViewController.excludedActivityTypes = [UIActivityType.addToReadingList,
 UIActivityType.airDrop,
 UIActivityType.assignToContact,
 UIActivityType.copyToPasteboard,
 UIActivityType.mail,
 UIActivityType.message,
 UIActivityType.openInIBooks,
 UIActivityType.print,
 UIActivityType.saveToCameraRoll
 ]
 present(activityViewController, animated: true, completion: )

But the UIActivityViewController is still giving me unwanted options.

I also thought to get and approach with NSExtensionItem but I am not sure about it.

Thank you

There are option available for Facebook and Twitter, You need to just add excludedActivityTypes. You have missing it.

Instagram option still not available in activity types

let image = UIImage(named: "TheImage")
let activityViewController = UIActivityViewController(activityItems: [shareText,image], applicationActivities: nil)

activityViewController.excludedActivityTypes = [.addToReadingList,
 .airDrop,
 .assignToContact,
 .copyToPasteboard,
 .mail,
 .message,
 .openInIBooks,
 .print,
 .saveToCameraRoll,
 .postToWeibo,
 .copyToPasteboard,
 .saveToCameraRoll,
 .postToFlickr,
 .postToVimeo,
 .postToTencentWeibo,
 .markupAsPDF
] 

present(activityViewController, animated: true, completion: )

I hope this will help you.

Apple provides support for some of the default UIActivityTypes that includes both Facebook and Twitter as required by you.

You can get a complete list of UIActivityTypes here: https://developer.apple.com/documentation/uikit/uiactivitytype

By default, all the UIActivityTypes appear in the UIActivityController. The activities you don't want to appear in the UIActivityController an be added in the exclude list, i.e

activityViewController.excludedActivityTypes = [.postToFlickr, .postToVimeo]

Also, whenever an App that includes a Share App Extension is installed on the device, it is also added to the UIActivityController.

Example:

WhatsApp. Whenever you install WhatsApp on your device, it will appear as a Share App Extension in the UIActivityController.
You cannot remove them but can only hide them from the UIActivityController's More option.

Let me know if you still face any issues.

As of now (march 2019), Instagram share option will only appear if you set an image and only that image on the activityItems. If you add a TEXT or URL object there as well the Instagram option will not show up.

Twitter, on the otehr hand would accept a TEXT and an IMAGE, but if you pass an URL too it will not show up as an option as well
