This is 8th part of my series about creating Swift AST in Swift. In this part I will cover special kinds of function-like declarations. You can find previous part here. Init In swift initializer is a common declaration, not required to be nested in class declaration. It is following pattern from…

In previous part I have cover struct and class declarations. In this part I will describe another fundamental pillar of Swift language: protocols. As usually, let’s start from looking on grammar: Well, it is looks like class and struct a lot. But instead of allow any declaration to be defined…

In previous part I have covered enum declaration, and found that there is two different enums in swift. In this one I will cover two entities at one time: struc and class. They are pretty similar to each other. But serving different roles at runtime. Struct Let’s start, as usuall, from…

In previous part I have covered function declaration. I started simplify grammar for AST needs. Making resulting types as easy to use as I can. In this part I will cover enumeration declaration. As usually, let’s look on grammar part: First of all, surprisingly, raw value enum has special syntax…

In previous part I have discussed let and var declrartions grammar. As I discovered, grammar reflects not all syntax restrictions of the language. In this part I will discover structure of function declaration. Let’s start from looking at formal grammar definition: Single root declaration is good. It also contains a…

In last post I have start covering Declaration grammar section of Swift grammar. In this post I will cover let and var declarartion. This is really tricky part with another portion of Swift grammar weirdinness. Let Let’t start from simpler one — let. Here is the grammar: Nothing conceptually new. Let’s…

In previous part I did build basic top level AST for Swift language. Nothing spectacular yet. Just some enums and strict data modelling. Today I am going to dig little deeper and replicate Declaration section of a Swift grammar. Let’s look into it: It is look all identical to statements…

I have to confess. I love types. I love power and constraints that type system brought to you. I don’t love typing, so I love when type inference allows me to not carry my types with me. And in my possession with types, I want to create something significant, something…

Recently Apple has released Swift 2.0 and I delve into it for production development. Before that, I have written my software around MVVM pattern in pure Objective-C. If you are interested in this approach you can check Github repo with the reference code. One of the fundamental components of Objective-C…
