wtf is xcodebenchmark?

XcodeBenchmark is a tool for measuring how long it takes Xcode, Apple's development environment for iOS and macOS applications, to compile a large codebase. It gives developers and hardware reviewers a consistent, repeatable way to compare compilation performance across different Mac computers. The benchmark works by compiling a substantial Swift and Objective-C project that uses CocoaPods, a dependency manager for Apple platform development. Running this compilation on a machine and recording the time produces a number that can be compared against results from other machines. This makes it useful for anyone deciding between Mac models, evaluating whether a hardware upgrade would meaningfully speed up their development workflow, or comparing the build performance of different processor generations. Apple Silicon (the M-series chips introduced from 2020 onward) changed compilation times significantly compared to previous Intel-based Macs. Benchmarks like this one help developers and tech reviewers put specific numbers on those differences using a realistic coding workload rather than synthetic tests that may not reflect day-to-day development tasks. The repository is written in Swift and targets macOS. It is not an application you distribute to users, it is a test you run on your own machine. The output is a compilation time you record and compare against community-shared results or other machines you have access to. The primary audience is iOS and macOS developers who spend significant portions of their workday waiting for builds to finish. Setting up the benchmark requires Xcode and CocoaPods installed on your Mac, which are standard tools in Apple platform development, so the barrier to running it is low if you already do iOS or macOS development.
