Swift Coding Interview Practice
Swift is Apple's modern programming language for iOS, macOS, watchOS, and tvOS development. If you're interviewing for an iOS engineering role at any company, Swift is the expected interview language. Its safety features, clean syntax, and expressive standard library make it well-suited for algorithm problems.
Why Swift for Interviews?
Swift combines the performance of C++ with the expressiveness of modern high-level languages. Optionals enforce nil safety, value types (structs, enums) prevent shared state bugs, and Swift's generics and protocol-oriented design model complex data structures cleanly.

Swift Interview Tip
Use Dictionary for hash maps, Set for O(1) membership, and Array for dynamic lists. Swift's filter, map, and reduce are great for collection problems. For tree and linked list problems, use classes (reference types) rather than structs. Know how to use enums with associated values for elegant state modeling.
