Compilation time can often be a silent productivity killer, especially when it’s consistently long and causes unnecessary context switching. In this talk, I’ll address how to reduce the time it takes for a project to compile, covering both clean builds and rebuilds. We’ll dive into tools like Xcode’s build timeline to better understand the build process and identify slow spots. I’ll share actionable tips for optimizing Swift compilation, removing unused resources, and converting external dependencies to prebuilt frameworks. You’ll also learn how to modularize your project to improve build efficiency. For advanced users, I’ll introduce Tuist as a solution for managing build artifacts and streamlining the process. By the end of the session, you’ll have the knowledge to make your builds faster and your team more productive.
