tikhop/intoerror

Swift macro library for automatic error type conversion.

Requirements

dependencies: [
    .package(url: "https://github.com/tikhop/IntoError.git", from: "1.0.0")
]

.target(
    name: "YourTarget",
    dependencies: ["IntoError"]
)

Attaches to enums and generates boilerplate code for you:

@IntoError
enum MyError {
    case specific(SomeError)
    case other(AnotherError)
}

Convert errors inline (sync only):

func fetch() throws(AppError) -> Data {
    try networkCall()^
}

Wrap function body for error conversion. Works with sync and async.

With typed throws:

@Err
func fetch() async throws(AppError) -> Data {
    try await networkCall()
}

With untyped throws:

@Err(AppError.self)
func fetch() async throws -> Data {
    try await networkCall()
}
