Swiftequivalent

Swiftequivalent is a term used in software development to describe the set of Swift-language equivalents for constructs found in other programming languages, or a hypothetical tool that maps code to Swift. The concept helps developers port code, compare feature parity, and assess migration effort. The name combines Swift with equivalent, signaling functional parity rather than literal syntax.

In practice, Swiftequivalent may refer to a methodology or catalog of mappings from languages such as Java, Python, C#, or C++ to Swift. It focuses on translating data types, control flow, and standard library concepts so that a non-Swift construct can be expressed in Swift with similar behavior. The aim is to aid code review, documentation, and automated or semi-automated porting processes.

Typical mappings include:

- Primitive types: int to Int, long to Int64, float to Float, double to Double; boolean to Bool

- Text data: string to String

- Collections: arrays and lists to [T], maps to [Key: Value]

- Nullability: null to nil, optional types in Swift

- Optional handling: if let and guard let for safe unwrapping

- Control flow: for loops, if statements, and switch to Swift equivalents

- Error handling: try/catch patterns and Swift error handling with do-try-catch

- Functional styles: map, filter, reduce replacing common functional patterns

- Concurrency: asynchronous patterns in other languages mapped to Swift async/await

Limitations include semantic differences, API availability, and memory management nuances. Swiftequivalent is not an official Apple feature; it is a descriptive concept used in migration planning and tooling. See also Swift, cross-language translation, and porting.
