Question 1

How do I run code after a delay with Dispatch in Swift?

Accepted Answer

Use the `Dispatch.after` method with a time interval and queue. For example, `Dispatch.after(1.0) { /* code */ }` runs on the main thread after one second, leveraging the overloaded method for simplicity, as shown in the README.

Question 2

Dispatch vs raw GCD: which should I use for iOS development?

Accepted Answer

Dispatch offers a cleaner, more Swift-friendly API that reduces GCD boilerplate, making code easier to read and maintain. However, if you need fine-grained control over GCD primitives or are already deeply familiar with GCD, sticking with raw calls might be more flexible.

Question 3

How to chain async tasks together with Dispatch?

Accepted Answer

Dispatch supports method chaining for fluent async flows, but the README lacks explicit examples. You can sequentially call async methods, though you may need to experiment or refer to community resources for best practices on error handling and dependencies.

Question 4

Does Dispatch work with SwiftUI or Combine?

Accepted Answer

Dispatch is compatible with SwiftUI and Combine as it wraps GCD, which is foundational for Apple platforms. However, for reactive patterns, Combine might be more integrated, and Dispatch serves primarily to simplify GCD calls rather than replace higher-level frameworks.

Question 5

What's the best alternative to Dispatch for modern Swift concurrency?

Accepted Answer

For projects using Swift 5.5+, native async/await with actors and structured concurrency is the recommended alternative, as it provides safer, more maintainable code. Libraries like Combine also offer more comprehensive solutions for complex asynchronous workflows.

Question 6

How do I create a custom serial queue with Dispatch?

Accepted Answer

Use the `Queue.custom` helper with a name and the `serial` attribute. For instance, `Queue.custom("my.queue", .serial)` creates a custom serial queue, abstracting away the verbose GCD `dispatch_queue_create` syntax detailed in the README.
