ReactiveSwift vs PromiseKit

Developers should learn ReactiveSwift when building iOS or macOS applications that require complex asynchronous operations, such as real-time UI updates, network requests, or event-driven architectures meets developers should learn promisekit when building ios or macos apps that involve complex asynchronous workflows, such as making multiple api calls, processing data sequentially, or managing ui updates after background tasks. Here's our take.

ReactiveSwift

Nice Pick

Developers should learn ReactiveSwift when building iOS or macOS applications that require complex asynchronous operations, such as real-time UI updates, network requests, or event-driven architectures

Pros

• It is particularly useful for managing state changes, handling user interactions, and coordinating multiple data sources in a clean, functional style, reducing callback hell and improving testability
• Related to: swift, functional-programming

Cons

• Specific tradeoffs depend on your use case

PromiseKit

Developers should learn PromiseKit when building iOS or macOS apps that involve complex asynchronous workflows, such as making multiple API calls, processing data sequentially, or managing UI updates after background tasks

Pros

• It's particularly useful for replacing nested completion handlers with flat chains, making code more maintainable and reducing bugs in multi-threaded environments
• Related to: swift, objective-c

Cons

• Specific tradeoffs depend on your use case

The Verdict

These tools serve different purposes. ReactiveSwift is a framework while PromiseKit is a library. We picked ReactiveSwift based on overall popularity, but your choice depends on what you're building.

The Bottom Line

ReactiveSwift wins

Based on overall popularity. ReactiveSwift is more widely used, but PromiseKit excels in its own space.
