I'm trying to use the following API in Swift: UIPasteboard: setItems(_:options:) , as suggested in this answer:

UIPasteboard.general.setItems([[kUTTypeUTF8PlainText as String: text]], options: [.expirationDate : Date(timeIntervalSinceNow: 10)])

However, it seems that the kUTTypeUTF8PlainText constant has been deprecated and I need to use the UniformTypeIdentifiers framework:

pasteboard.setItems([[String(UTType.plainText): string]],
                    options: [.expirationDate: Date(timeIntervalSinceNow: 120)])

However, the setItems: method accept only String type as the key, so I need to somehow convert the UTType.plainText to be of type String. How can I achieve this?

CodePudding user response：

You should use the identifier property (also note the equivalent type is called utf8PlainText):

UTType.utf8PlainText.identifier

As the documentation says:

API that doesn’t use UTType uses a String or CFString to refer to a type by its identifier.

And UIPasteBoard is such an API.
