When writing iOS applications, the creation and management of certain files is necessary in order to test on a real device. The exact files required depends on whether you are currently developing or preparing for distribution. We will focus primarily on development.
By the end of this chapter, you will have created a P12 certificate file and a development provisioning profile, both of which are required if you want to make full use of the recipes throughout this book. Along the way, you will learn the ins and outs of various tools including Apple's iOS Provisioning Portal, which you will come to use extensively during your time as an iOS developer.
Don't worry if it doesn't all make perfect sense at first. If you follow the steps detailed in each recipe, you will end up with the development files required to work through the rest of the book.
