Finally, we reached the end of this chapter. This chapter covers some details of Objective-C, such as property attributes, which you have been typing in but do not have a clear idea of. We also covered memory management guidelines, where I have outlined some tips and tricks to add to your knowledge of memory management and debugging memory-related issues in your code. This chapter just covers a small subset of memory management and I hope that you have dived deep into the previous chapters, where the various memory management techniques are covered more in-depth. Finally, one more chapter lies ahead, where we will go through some of the new tools and functionalities of Xcode 6, which you can use in your projects. So, let's proceed, shall we?
