Here's our take.

PromiseKit

Nice Pick

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

ReactiveSwift

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

The Verdict

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

The Bottom Line

PromiseKit wins

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