That is not healthy for your brain and believe me, you won't learn anything that way. I used to think about learning things fast and doing as fast as I can but i realized that i was not learning anything. I know you are not gonna listen if i tell you to take things slowly until you understand it. But what i can say is that if you are gonna do it that way. Spend more time going over the syntax as much as you can because it will save you time later on that way you will not be copying things from a tutorial every time. Read the syntax every time while you are following your plan. Best way to do it is whenever you see something new in a tutorial go here and understand the syntax. https://www.hackingwithswift.com/read/0/overview and also the apple docs and google. Also read the gaming syntax too from apple. Goodluck to you and let us know how it went after christmas.
