Summary:
With the Cocoa frameworks, it is common to create an object and then set several of its properties. For example:
let action = UIMutableUserNotificationAction()
action.identifier = "REPLY"
action.title = NSLocalizedString("Reply", comment: "Reply")
action.activationMode = .Foreground
action.destructive = false
action.authenticationRequired = true
To make such code less noisy, it would be nice if Swift provided a "property initialization" syntax, similar to the "object initializer" syntax in C#. For example, the above could be written as
let action = UIMutableUserNotificationAction() {
.identifier = "REPLY",
.title = NSLocalizedString("Reply", comment: "Reply"),
.activationMode = .Foreground,
.destructive = false,
.authenticationRequired = true
}
This would lead to more concise, readable code, and reduce the temptation to create lots of convenience initializers with different combinations of parameters.
