Summary

As you can see, Xcode is a big step forward in the right direction for developers with the introduction of new tools such as view hierarchy debugger, preview editor, and the addition of new functionalities such as allowing storyboards and NIBs to be used as launch images for your application instead of just static images. With all these new components to play with, Apple has made it much easier and better for developers to create and code cool projects with ease and reduce the effort to do so. With this,I leave you to your coding tasks and hope that you have a great time reading this book and getting some useful tips. With this, I bid you, "Goodbye, and enjoy coding."

P.S. If you wish to dig more into Xcode 6, here is a link to the official Apple documentation for Xcode 6: https://developer.apple.com/library/ios/documentation/DeveloperTools/Conceptual/WhatsNewXcode/Articles/xcode_6_0.html.
