报告内容

（一）

I’m reading this document–The Swift Programming Language.
I think I have found two mistick in it,but I don’t know how to reprot them.

The first one is in chapter “Automatic Reference Counting”,there are 3 pictures in the section of “Resolving Strong Reference Cycles Between Class Instances”,the pictures does not match the example code,you can’t find the expression “var number73”.

The second one is in the chapter of “Protocols”,there is a example code after the second NOTE in the section “Optional Protocol Requirements” .I think maybe a “?” is missing after the “dataSource?.fixedIncrement”.
