SIR: Swift Intermediate Representation

Swift IR or SIR is an intermediate representation that we use in Swift Export to represent the structure of Swift declarations.

SIR:

• Represents only Swift declarations. It knows nothing about function bodies.
• Does not represent all possible Swift declarations at the moment. We add new nodes when we need them.
• Is not intended to be a source-accurate representation of Swift sources like swift-syntax.
  • First and foremost, it is a tool for Kotlin -> Swift translation, and designed in a most suitable way for it.
  • We don't develop it as a general-purpose tool.

Adding new nodes

New declaration interfaces and classes are generated automatically from DSL. See tree-generator for more.
