Reading the forums I can tell you keep this book updated. However I was curious if you kept a public changelog? It’s peace of mind when investing in a resource for something that changes so quickly like Swift, to know the publisher wants to create more of a “living” resource. Do the changes follow the errata 1:1? Or perhaps the changelog is for customers only?
Thank you for your suggestion - much appreciated. We don’t have a public change log for the book at the moment after all but we will definitely and certainly think about creating, adding and maintaining one some time and at some point in the future.
