I was talking with a colleague who was interested in reading up on Swift using the Swift Programming Language book, but wasn’t happy with the version on the Swift website, broken up into chapters. He asked if I knew of a version that was available in PDF that he could read.
I thought, well, Apple must have provided it in PDF, and probably other formats as well. Instead, all I discovered was that Apple chose ePub as the sole winner in its format war, and only provides that format, both in the Apple Books store, and on the Swift website.
Here I am thinking: I can read a PDF anywhere. ePubs? Not so much.
Not everybody is doing Swift development on Apple hardware and software. If Swift is going to be a language that is cross-platform friendly, its documentation needs to be as well.
A little conversion job later, I bring you The Swift Programming Language 5.1 in PDF format (updated Oct 9 2019):
The license remains the same as before: Creative Commons Attribution 4.0 International (CC BY 4.0) License. The content is also exactly the same, but conversion being what it is, if you find any conversion errors, please email.

Thanks, enjoy the download, and happy developing!
