Question 1

How do I set up a basic HTTP server with Embassy in Swift?

Accepted Answer

Create a SelectorEventLoop and DefaultHTTPServer, define an SWSGI app to handle requests, and run the event loop. The README provides example code showing how to bind to localhost or external interfaces.

Question 2

Embassy vs Vapor: which is better for Swift web development?

Accepted Answer

Embassy is minimal and embeddable, perfect for testing and lightweight services, while Vapor is a full-featured framework for production web apps. Choose Embassy for simplicity and zero dependencies, Vapor for built-in tools and scalability.

Question 3

Can Embassy handle WebSocket connections?

Accepted Answer

No, Embassy is designed for HTTP only and does not natively support WebSockets. For real-time features, you would need to implement custom solutions or use additional libraries.

Question 4

How to implement URL routing with Embassy?

Accepted Answer

Embassy has no built-in routing; you must parse the PATH_INFO from the environ dictionary in your SWSGI app and handle different paths manually, which offers flexibility but adds development overhead.

Question 5

Is Embassy suitable for use in production iOS apps?

Accepted Answer

Embassy is best for development, testing, and internal tools due to its minimal security and lack of production-ready features. For public-facing services, consider frameworks with robust security and performance optimizations.

Question 6

How to throttle bandwidth or simulate network delays with Embassy?

Accepted Answer

Use the event loop's call methods with delays to control response timing, and manipulate swsgi.input or sendBody for bandwidth control. This is useful for testing network conditions in UI tests.
