Open in Safari with UIActivityViewController? - ios

Question

I'm sharing a URL via UIActivityViewController. I'd like to see "Open in Safari" or "Open in browser" appear on the share sheet, but it doesn't. Is there a way to make this happen?
Note: I am not interested in solutions that involve adding somebody else's library to my app. I want to understand how to do this, not just get it to happen. Thanks.

Yes, you could add your custom action to Share sheet in iOS
You would have to copy this class.
class MyActivity: UIActivity {
var _activityTitle: String
var _activityImage: UIImage?
var activityItems = [Any]()
var action: ([Any]) -> Void
init(title: String, image: UIImage?, performAction: #escaping ([Any]) -> Void) {
_activityTitle = title
_activityImage = image
action = performAction
super.init()
}
override var activityTitle: String? {
return _activityTitle
}
override var activityImage: UIImage? {
return _activityImage
}
override var activityType: UIActivity.ActivityType {
return UIActivity.ActivityType(rawValue: "com.someUnique.identifier")
}
override class var activityCategory: UIActivity.Category {
return .action
}
override func canPerform(withActivityItems activityItems: [Any]) -> Bool {
return true
}
override func prepare(withActivityItems activityItems: [Any]) {
self.activityItems = activityItems
}
override func perform() {
action(activityItems)
activityDidFinish(true)
}
}
Please go through the class you might need to change a few things.
This is how you use it.
let customItem = MyActivity(title: "Open in Safari", image: UIImage(systemName: "safari") ) { sharedItems in
guard let url = sharedItems[0] as? URL else { return }
UIApplication.shared.open(url)
}
let items = [URL(string: "https://www.apple.com")!]
let ac = UIActivityViewController(activityItems: items, applicationActivities: [customItem])
ac.excludedActivityTypes = [.postToFacebook]
present(ac, animated: true)
I have done this for one action, and tested it, it works.
Similarly you could do it for other custom actions.
