Can I use the iOS SDK for any site in all types of Swift applications?

Question

Swift

For example, there is an iOS SDK for Stripe - https://github.com/stripe/stripe-ios
Written in Objective-C, but let's imagine that it would be written in Swift.
Would this mean that this stripe-ios could be used in a) web b) desktop
applications written in Swift? Or is it just for iOS?
The question is not only about this library, but in general about this kind of library in Swift for iOS. I think they usually have an SDK prefix

Answer 1

no matter what sdk is written on. the only difference is whether it is platform dependent or not.
for example, uikit is only available in yaoshi. accordingly, any code that uses it will only work on Yaoshi.

Answer 2

What the hell is a website?! If it says iOS , it means only one thing... use within an iOS application .
Sites are written in HTML / CSS / JS, and here Swift and iOS are not clear. The backend in Swift has nothing to do with the visual component.
