It's going to be Xcode and more

Much of this book, particularly the later chapters, will look at leveraging the considerable power of the Xcode-integrated development environment, in order to familiarize the reader with many aspects of development that go beyond code writing, to include debugging, performance measurement and improvement, working with source control within a team, and many others.

Software development is rarely a matter of using one single program, and we will be utilizing several tools other than Xcode to get the most out of the time we spend coding, compiling, and testing our work. You might be pleased to learn that none of these tools are going to cost you any money (although like any other tool, they come at the cost of a certain amount of time to be invested in order to reach a moderate level of proficiency). You might be even more pleased to learn that we will be covering this ground step by step, and no previous knowledge is assumed.
