Gain the basic understanding of how to create apps
Get to know your way around Xcode programming software

This course is designed for beginner to advanced. You can also go though it more than once. The first time you will mostly be running along with me in the videos and doing everything at the same time. Though as you get better challenge yourself and try to do the challenge without viewing the video solution or solution code.

I'm happy to help you as much as possible through this journey so feel free to email me if you come accross any problems or have any questions.

Mac Computer with Catalina 10.15 installed
Xcode 11.3 Installed (free from the AppStore)
