In Xcode or other development environments, learning to program is a painstaking thing, and you need to spend a lot of time in it. But there is one more element that you may have overlooked. No matter what type of development you're learning, or if you're just interested in a particular programming language, you can learn a lot about programming without having to write a line of code. This is because Swift

In the complex field of "communication", it is much more difficult to write coherent passages that can be grasped and understood by humans than to knock out a few lines of software code that does not "vomit" the interpreter or compiler. That's why--in terms of software development--all documents are probably bad. Moreover, because writing is much more difficult for people to write than for machines, the document may continue to suck in the foreseeable
