Xcode has seen a lot of improvements and changes. Creating an application has become easier and more integrated than it used to be a couple of years ago. Certificates were a big hassle, which has now been integrated into the Xcode workflow. Some developers might feel that the way release binaries are created are a bit strange and rather inconvenient, whereas on the other hand, you no longer have to search for it, zip it, and so on. It is all integrated. Creating an application with Xcode is much faster and easier, add to that the introduction of the Swift language makes it simply a breeze. Hope this book has been able to introduce you to Xcode and get you started and look forward to seeing what you can achieve with this knowledge.
