I'm a full-time Swift author and speaker, and I run Hacking with Swift – the world's largest site dedicated to teaching developers how to build apps with Swift and SwiftUI. I've written books about iOS, macOS, watchOS, and much more – I enjoy hacking around with Swift regardless of the platform, and love passing on what I learned to others. For more information you can visit my site at hackingwithswift.com, or follow me on Twitter @twostraws.
