How to use?
Traditionally we compose a UIAlertController like this:
let greeting = false
let alert = UIAlertController(title: "title", message: "message", preferredStyle: .alert)
alert.addAction(.init(title: "Cancel", style: .cancel, handler: nil))
if greeting {
alert.addAction(.init(title: "Hello", style: .default, handler: nil))
} else {
alert.addAction(.init(title: "World", style: .default, handler: nil))
}
present(alert, animated: true, completion: nil)Now, with XLAttributedString, we can use SwiftUI-like syntax to declare NSAttributedString:
let greeting = false
UIAlertController(title: "title", message: "message", preferredStyle: .alert) {
Action.cancel("Cancel")
if greeting {
Action.default("Hello", handler: nil)
} else {
Action.default("World", handler: nil)
}
}.presented(by: self, animated: true)Requirements
