alertTitle
A short description of the reason for the alert.
Declaration
var alertTitle: String? { get set }Discussion
Use this property to provide a short description of the reason for the alert. You may specify a string with the text you want to display or you may specify a string to use as a lookup key in your app’s Localizable.strings file. The default value of this property is nil.
Title strings should be short, usually only a couple of words describing the reason for the notification. Apple Watch displays the title string as part of the short look notification interface, which has limited space.
