Throughout Federico’s review, you’ll find sections labeled ‘The Details.’ This new feature of the review is designed to make it easier for readers to discover smaller, interesting details about various apps and features of iOS and iPadOS 15. The book is a great companion to Federico’s review that goes into depth on some of the most interesting features coming in Apple’s OS updates. The book, written by Federico and me, includes interviews with developers about their reactions to WWDC, FaceTime, HomeKit and tvOS, Reminders’ new Smart Lists feature, Apple Maps, Quick Note, and our iOS, iPadOS, and macOS first impressions. The second eBook is a compilation of the eight stories we published over the summer as part of our summer OS preview series. Of course, the first eBook is a fully interactive version of Federico’s review complete with all the images, videos, and links to shortcuts you’ll also find on .Ģ021 OS Preview Series: MacStories Extras.
