AwaitlessKit

Why it exists

Swift’s async/await adoption is all-or-nothing, and you can’t easily call async functions from sync contexts. AwaitlessKit makes the migration incremental. It bypasses Swift’s concurrency safety mechanisms, so it is a migration tool and not a permanent solution.

What it does

@Awaitless family

async to sync, Combine publisher or completion handler.

@Awaitable family

Publisher and completion-handler APIs to async/await.

PromiseKit integration

Conversion in both directions, as a separate product.

@IsolatedSafe

Thread-safe wrappers for nonisolated(unsafe) properties.

Use it

class DataService {
    @Awaitless
    func fetchUser(id: String) async throws -> User {
        // Your async implementation
    }
}
