I had trouble following too at first but I found it very helpful to look at Apple鈥檚 documentation for each of the subjects. I don鈥檛 mean the actual documentation for a function or a call but, let鈥檚 say the topic of properties in general. What these short tutorials cover is most of the coding basics you will stumble upon in your professional work and they tend to go fast. They can be overwhelming but each time you go through them you will notice, or understand, something new.
