Very cool. App thinning seems to be the golden feature of Swift 5. I am dying for the day (if it ever comes) that UIKit and SpriteKit work natively with Linux and Windows frameworks, so that I can finally make Swift a daily driver.

As someone who hasn't yet put in the time with swift, i get the sense that every version release of Swift includes a surprising amount of breaking changes. Are these edge cases that don't really effect anyone or does every Swift project you undertake basically cement itself into a swift version?

"Unqualified references to Result in any of your code that imports the Foo module will resolve to Foo.Result" That feels like it potentially can have weird unintended consequences

Swift matrix use looks pretty gross compared to Julia, R or Python (NumPy) https://developer.apple.com/documentation/accelerate/simd/wo... Is there an other way?

Swift has largely stopped making source-breaking changes.

Another way to do what?

This was done so Swift’s Result doesn’t conflict with your library’s hand-rolled Result.

2 to 3 was brutal. Otherwise totally fine.
