Jan 15 2019 · Swift 4, iOS 12, Xcode 10
Notes: 01. Introduction
ExpressVPN is available as an app on iOS and macOS. The shield button we're recreating is central to the app, but you don't need to sign-up to the app to see it in action. The videos in the course include screen-recordings where appropriate.
The course from Lea that was mentioned is Reproducing Popular iOS Controls.
