RxSwift v1.0 Errata

📚 Official Books RxSwift
44

Chapter 9, p. 180. At the end of the example(of: "with LatestFrom") block, there should be a call to disposable.dispose().

Same errors in pages 151 and 152

46

On page 110 of the pdf in the distinctUntilChanged(_:) problem, there is no space between the two quote characters (e.g. ""), providing a different result from the block than the one shown in the example output. Ensuring your example does have the whitespace (e.g. " ") resolves the issue.

There is an errata in the podfile archive of chapter 23. In the target ‘MacTweetie’, you should add the keywords “do” and “end”. If not we’ll receive an error warning when we try to execute the command pod install. Therefore, correct text would look like:

end

it worked fine for most readers, but I did the change you request in case it wasn’t running for anyone else
