Showing dictionary definitions using UIReferenceLibraryViewController
Swift version: 5.1
UIKit has a built-in dictionary and a built-in way of showing definitions for that dictionary, all done using UIReferenceLibraryViewController. Before you try using it, you should call its dictionaryHasDefinition() method to make sure a definition exists, like this:
if UIReferenceLibraryViewController.dictionaryHasDefinition(forTerm: "Swift") {
// code
}If a definition exists, you create an instance of the view controller using the word you want to show, then present is as normal:
let referenceVC = UIReferenceLibraryViewController(term: "Swift")
present(referenceVC, animated: true)
