Practical Guides
A few years ago, I wrote and revised several editions of an ebook about networking and security in iOS, which I now self-publish. I've revised it three times: for iOS 8, iOS 9, and iOS 10. You can purchase it in ebook form, by clicking below, and download it immediately. I've also made it available as a print-on-demand book that can be produced and shipped immediately as well via Createspace.
