Good finds

[felix91gr]

Here I'm gonna put the libraries that seem to be:

• Well supported
• Well tested
• Cross-platform
• Production-ready: developed enough to be used by third parties. For example, CompilerKit fits all of the above but it's not yet finished, and thus can't be put on the same list as everything else.

Command Line UI tools

• SwiftCLI

Workflow-enabler frameworks

• Quick: a behavior driven development framework.
• Nimble: matcher and testing counterpart for Quick.
• Spectre: a BDD framework and test runner for Swift.
• ReactiveSwift: Streams of values over time. I don't know what that is exactly, but it seems to be very useful. It has like 200 contributors as well.
• PromiseKit: async++
• Deferred: a "futures library"
• AsyncNinja: primitives for enabling concurrency and reactive programming.
• Result: microframework for modeling and handling errors in code.

System libraries

• Compression: Compression algorithms
• Perfect-Zip: utility for Zipping files
• RandomKit: this one's going to be obsolete after the "Random Unification" proposal gets rolled out. But until then, it's probably very useful.

Signal and image processing

• EasyImagy: basic image processing toolbox

Data Structures

• SwiftPriorityQueue
• SwiftGraph
• SortedArray

String Processing

• Guitar: string and regex library written in Swift.

If we add ReactiveSwift (spoiler: we should) we should add RxSwift, too. Both are just different flavors of the same concept.

You can see both as sequences that may be async. You can map, filter and flatMap on them. Plus they have some elements of the observer pattern and allow you to have side effects.

Additionally:
Both PathKit and Files provide a better API to handle paths and their contents.

Indeed! I'd forgotten about them. They look pretty great!
Files passes every test on my side, and I've been working with kylef to update which tests that are failing can be passed on PathKit

It looks like what PathKit needs is just a little more love from the Foundation team to get 100% passing :)

I tend to agree. I downloaded RxSwift as well, but couldn't make it pass its tests. I think it depends on Darwin directly. I'll post an issue to them to see if they intend to support Linux and if what they're importing from Darwin can be replaced with something from Foundation :)

I learned part of what I think was Reactive Programming with C#. You had events (e.g. a UI button press or a socket recieving new info) to which you could subscribe functions. Then when those events were triggered, all of the functions subscribed to them would activate and recieve the events' predefined parameters as input. This is like that, but more general? Or am I way off?
