Installation

Your first operation.

TaskLoom requires Swift 6.3. Apple deployment targets start at iOS 18, macOS 15, tvOS 18, watchOS 11, and visionOS 2. The portable concurrency surface also supports Linux.

Add the package

Add this dependency to your Swift package, or enter the repository URL in Xcode’s package dependency dialog. Until the first tagged release, select the main branch; pin a commit for reproducible builds.

.package(url: "https://github.com/modern-swift-dev/taskloom-swift.git", branch: "main")

Add the library product to your target’s dependencies:

.product(name: "TaskLoom", package: "taskloom-swift")

Compose and execute

import TaskLoom

let value = try await AsyncOperation.just(21)
    .map { $0 * 2 }
    .execute()

The operation is lazy. map transforms its result, and execute starts it. Use AsyncTask for closures that cannot throw.
