Unable to share NSString object using UIActivityViewControll

Answer 1

Ran into this problem with a custom UIActivityItemSource where I was passing back kUTTypeData that most providers understand for the dataTypeIdentifierForActivityType delegate method instead of kUTTypeText. Simple case overrides fixed the issue in my case. Just another reason the error above could be popping if anyone sees it.

open func activityViewController(_ activityViewController: UIActivityViewController, dataTypeIdentifierForActivityType activityType: UIActivityType?) -> String {
    switch activityType {
    case UIActivityType(rawValue: "net.whatsapp.WhatsApp.ShareExtension"):
        return kUTTypeText as String
    default:
        return kUTTypeData as String
    }
}
