I think you're missing the point. iOS 13 is not the value proposition of the library, it's simply one small feature of comparison of many and isn't highlighted beyond a simple mention. The library provides just as much value if you are starting a new app today and choose to target iOS 26+.

> And with Apple's history of source-breaking changes over major platform updates, plus given how even huge libraries/tools like Alamofire, Realm, RxSwift, Cocoapods eventually succumbed to oblivion, I can't think of why an Apple developer with any modicum of discernment would choose PointFree's tools over Apple's own--unless they are themselves caught by the allure of reinventing the wheel.

Isn't this just a blackpilled take in general? You're complaining that Apple software breaks, that other third party software is discontinued, and this somehow leads to the conclusion to avoid this library?

If you think that through, the answer is: of course! Take for example the move from Swift 1 to 2 (an extreme example but illustrates the point).

If you used a third-party lib written in Swift 1 and you had to move to Swift 2 because the next version of iOS requires the latter. Then you’ll have to wait for the lib developer to publish a version of their third-party lib for Swift 2 before you can publish your app. That’s the same kind of risk that you’re exposed to with source-breaking changes.

Admittedly, source-breaking changes have gotten less frequent in Apple’s major tooling updates, but the right mindset when developing for walled gardens like Apple is that it will happen again.
