This is a formal way of saying "take this AST and figure out what its meaning is." Exactly how you perform semantic analysis depends a lot on the specifics of how your AST works and what you're trying to do. Once you have your AST, the next step is semantic analysis. Hopefully you have a strong grasp of trees and recursion, because compiler work uses them everywhere.

You can run your parser over Objective-C code and get an Abstract Syntax Tree (AST) out. Once you have a parser, a lot of the hard work is done, but there's still plenty of interesting challenge ahead for you. Until you've got a lot of experience with compiler work, you'd be better off finding an existing parser than trying to build your own. This makes creating a proper parser for them much more difficult. C and Objective-C are level 1, context-sensitive languages, because of the way typedefs work: the same string of code can parse in two different ways, with two different meanings, depending on whether or not the symbol it's reading is a type. It defines four levels of language complexity from 0 (very difficult to parse) to 3 (very easy to parse.) Most modern programming languages are level 2, context-free languages, because it's difficult to create a useful language without a recursive grammar, which is what differentiates level 2 from level 3. From the vocabulary you're using, you may already know a few things about parsing theory and the Chomsky hierarchy. Unfortunately, C (and by extension any superset of the language, such as Objective-C) is difficult to parse.
You're right in that your overall task is a source-to-source compiler, and that you need to start with a parser.

We start by breaking it down into smaller and smaller tasks until we get them down to the level of a problem we know how to solve. But then again, so are most things worth doing in programming. If you're new to Swift you will find this tool very valuable as a aid for learning Swift if you have Objective-C experience.This is a pretty big task.

Supports code using ARC or manual memory management. Allows manual customization of generated code using and annotations. Gathers type information from user specified header files to improve conversion. Converts blocks to Swift closures equivalents Preserves formatting and comments inside your methods. Handles Optional "?" types with sophisticated type inference. Translates frameworks like Foundation, UIKit, Quartz and others with correct method mappings and constants mappings. Translates Implementations/Interfaces to Classes Here are some of the translator features. Conversion is super fast is run directly on your Mac. You can customize type mappings from Objective-C to Swift as well as method mappings with an easy to use template system. The tool is highly sophisticated and customizable. That said, we know the tool drastically reduces the time required for upgrading to Swift! You should test every function of your converted code to make sure it works as expected.
Some code blocks may require manual conversion.
WARNING: You may need to spend some time to customize and optimize the conversion settings for your project. O2Swift can save you WEEKS of effort when converting Objective-C to Swift for significant projects! It automates around ~95% of work when converting to the new Swift programming language. O2Swift automatically translates old Objective-C source code to Swift.
#C to swift converter upgrade
If you're a serious app developer you know you need to upgrade your apps to the Swift language or risk being left behind. Swift code is more maintainable and "safer" than Objective-C.
