Desktop tool to quickly explore and analyze Swift Intermediate Representation (IR) generated by the LLVM compiler, and also generate assembly code.

• Deep Code Understanding: Developers can see how Swift code is transformed into both LLVM IR and assembly code, helping them better understand optimization and low-level behavior.
• Advanced Debugging: Viewing LLVM IR and assembly can help identify performance issues or hard-to-trace bugs in source code.
• Education and Learning: A valuable educational tool for learning about compilers and how different language constructs translate into intermediate representation and assembly.
• Optimization: Helps identify and optimize code snippets that are not compiling efficiently by providing insights from both LLVM IR and assembly.
• Comparative Analysis: Allows you to compare how different approaches or code versions generate different IR and assembly code, facilitating the choice of best coding practices.
• IA Gemini: You can see how to improve your code and compare LVVM and Assembly with the help of Gemini.

• Onone: Compile without any optimization.
• Osize: Compile with optimizations and target small code size.
• Ounchecked: Compile with optimizations and remove runtime safety checks.
• O: Compile with optimizations.
