Hi there, I bought a Mac Mini (living in Beijing at the moment) and wanted to download the "Develop in Swift" books and materials, but the link does not go to my ebook app, nor does it download anything. It simply freezes or gives an error message. May I know how to fix this please?

Howdy doodle do: I will be grateful if anyone in the know could tell this noob what am I supposed to attempt after finishing Learn to Code 2 playground? I'm almost there.
