Announcing Swift Algorithms

Algorithms are powerful tools for thought because they encapsulate difficult-to-read and error-prone raw loops. The Algorithms package includes a host of powerful, generic algorithms frequently found in other popular programming languages. We hope this new package will help people embrace algorithms, improving the correctness and performance of their code.

Swift Algorithms is a new open-source package offering a suite of generic sequence and collection algorithms, such as chunking, combinations, permutations, and random sampling, designed to replace error-prone loops with clear, performant code.

It includes methods like chunked(by:) for splitting collections by adjacent element conditions and chunked(on:) for grouping by transformed values, enhancing code readability and correctness. The package serves as an incubation space for algorithms destined for the Swift Standard Library, complementing the Swift Evolution process by enabling early community feedback and iterative development.

It focuses on pragmatic, widely applicable algorithms that align with Sequence and Collection protocols, excluding currency types or overly specific operations. Contributions are evaluated for readability, commonality, consistency, and their ability to avoid correctness or performance issues.
