In a post on its Swift blog (https://swift.org/blog/swift-benchmark-suite/) Apple says Swift’s benchmark suite is now open source. The uite contains source code for benchmarks, libraries, and utilities designed to help track Swift performance and catch performance regressions before they are committed, including:
° 75 benchmarks covering a number of important Swift workloads;
° Libraries providing commonly needed benchmarking functions;
° A driver for running benchmarks and displaying performance metrics;
° A utility for comparing benchmark metrics across Swift versions.
