First, thank you Chris and Micah for these fabulous courses. I have learned a great deal!
I am 71 and retired. I am not a novice to programming since I spent 15 years in IT. I know many languages, including c++ and python. My introduction to Swift and Xcode did not go well. I found learning Swift on your own to be impossible. Your courses have gotten me to a point that I feel capable of writing my own app. I am hoping to launch that app and make it available on the App Store at some point.
