feature request: Add exercises to each chapter

[fmustafa17]

Only Chapters 1, 2, 8, and 9 have exercises. The book would have a greater impact if there were exercises at the end of every chapter

Agree. And a link to recommended blogs or forums for the book where learners can exchange help. Peter mentioned he used to post to a blog helping others what he learned when he first started using SwiftUI*pg.xvii. A referenced forum for the SwiftUI learners to help and support each other would be very useful.
