The advertisement of the book doesn’t say which versions it supports. Having good faith on this website I purchased the book and only after that I found out it was for older versions of Xcode, Swift and Realm. Accompanying source code doesn’t work obviously for me on Xcode 10 and Swift 4.2.
This is so annoying. If it was clearly indicated before purchasing the book, I would not have bought it.
Now what do I do? Can I get source code for latest versions?
