PassiveLogic Swift WebAssembly Open Source Contributions #1
Description
Who is PassiveLogic?
PassiveLogic is a company creating autonomous building control solutions to pave the way for a new generation of high-efficiency building technology.
We ❤ Swift!
What is PassiveLogic doing?
We're actively working to use our existing Swift codebase in our web apps, using Swift SDK for WebAssembly.
To enable using Swift for WebAssembly with large-scale web apps, we're contributing support for Swift WebAssembly compilation to a wide range of open source repositories. These contributions work together to enable common web app functionality, such as connecting to servers using websockets, making HTTP requests, creating SQLite databases, and much more.
Active Contributions
Following are active contributions to enable using swift for large-scale web apps. This is a working list, and will be updated over time.
DispatchAsync
A new lite drop-in replacement of GCD, implemented using SwiftConcurrency. GCD is not currently included in the Swift SDK for WebAssembly. DispatchAsync enables compiling Swift code that uses GCD, but using a Swift Concurrency backing instead of the unsupported GCD library.
- Create working proof of concept private using our own codebase to dog-food the concept.
- Create initial open source repository (in progress). This repository will be a temporary stepping stone towards hopeful integration in libDispatch or some other place in the Swift toolchain that enables
import Dispatchin Swift WebAssembly builds.
See feat: Initial implementation of many GCD API's using Swift Concurrency dispatch-async#1 - Add initial wave a unit tests, some of which are ported from libDispatch. See feat: Add additional tests for DispatchAsync dispatch-async#2
- Migrate DispatchAsync into the Swift SDK for WebAssembly

RxSwift
NOTE: RxSwift is a very difficult dependency to compile to wasm, due to extensive GCD usage. We have a proof of concept working, but may opt to elide this dependency instead.
