View Swift Property

Swift Property Wrappers Written by Mattt June 24th, 2019 Years ago, we remarked that the “at sign” (@) — along with square brackets and ridiculously-long method names — was as characteristic of Objective-C as parentheses are to Lisp or punctuation is to Perl.

Then came Swift, and with it an end to these curious little 🥨-shaped glyphs. Or so we thought.

At first, the function of @ was limited to Objective-C interoperability: @IBAction, @NSCopying, @UIApplicationMain, and so on. But in time, Swift has continued to incorporate an ever-increasing number of @-prefixed attributes.

We got our first glimpse of Swift 5.1 at WWDC 2019 by way of the SwiftUI announcement. And with each “mind-blowing” slide came a hitherto unknown attribute: @State, @Binding, @EnvironmentObject…
