Introduction The book is divided into three major sections: Networking should be simple, and security should be automatic. And money should grow on trees. Despite how intuitive it is to pick up and use an iPhone or iPad, requiring little thought as to how it connects to a cellular or Wi-Fi network, it becomes complex as soon as you drill down to any details. This is especially true when connectivity fails, and you try to troubleshoot. Privacy deserves the attention it’s now getting. Your information is your own to choose how it’s shared, whether it’s your location, your food preference, or your address and phone number. iOS and iPadOS provide tools that enhance your ability to control that. Security is an even denser area. Apple makes its default choices reasonably secure, but to ensure real protection for your data— when you select and use passwords, while your bits are traveling through the æther, or in the event that your device is stolen—you need to know how it all works. Note: Apple split iOS into two parts in its latest release. iOS is now the name of the operating system that runs an iPhone or iPod touch, while iPadOS naturally powers the iPad. Because nearly everything covered in this book remains identical across both systems, I will frequently refer to them collectively as “the OS” to avoid repetition.
