iBooks that Won't Download or Update
I've had good luck with iBooks. I use it to organize a fair number of game books on my laptop, and I've started picking up some other books which go into iBooks. And some of those are even provided by Apple. But those are the ones I'm having trouble with.
Specifically, the Swift Programming Language series. They're updated on my phone (Swift 2.1), but on my Mac they show as the Swift 2 Edition, even when it looks like I'm downloading the 2.1 edition at first. For what it's worth, The Swift Programming Language shows the 2.1 Edition in the title bar. But Using Swift with Cocoa and Objective-C consistently fails to download.
What do I have to manually clear or delete to make these download and show up correctly?
