To-do list iOS app
It's been over 2 years since I built an iOS app and a lot has changed in the iOS ecosystem since then. For instance, I have an app on the App Store called typs which was written in Swift 1. And when I tried to open it in Xcode 9, it woudn't even build the app successfully.
Hence I decided to referesh my knowledge and learn how to build a simple To-do list app from scratch in iOS 11 & Swift 4.
I found this really short and helpful course on Udemy that walks you through how to build a to-do list app.
