Declaration

optional func tableView(_ tableView: UITableView, canHandle session: any UIDropSession) -> Bool

Parameters

• tableView:

  The table view that’s attempting to handle the drop.

• Supporting drag and drop in table views

Return Value

true if the table view can accept the dragged data, or false if it can’t.

Discussion

Implement this method when you want to dynamically determine whether to accept dropped data in your table view. In your implementation, check the type of the dragged data and return a Boolean value indicating whether you can accept the drop. For example, you might call the hasItemsConforming(toTypeIdentifiers:) method of the session object to determine whether it contains data that your app can accept.

If you don’t implement this method, the table view assumes a return value of true. If you return false from this method, the table view doesn’t call any more methods of your drop delegate for the given session.
