Where can I find discussion or errata for IOS Apprentice fifth edition book, for IOS 10, Xcode 8 and Swift 3? Checking forum with IOS V.5s, I found out their pages and discussion did not match with my book. I need to find an errata or a place to ask some coding question regarding the book on page 238. Thanks.
It’s all here in the forums. There isn’t a big list of the errata all in one place, so if you can’t find the answer by searching the forums, then the quickest thing to do is to simply ask your question. 
We’re usually pretty quick at answering them!
