Slides from a talk I gave at Nashville CocoaHeads on 7/29/15.

For more information on Nashville CocoaHeads check out this website:

Here is the list of compiler flags I use in my projects and reference in the talk. You can easily copy the whole list, paste them into Xcode since the spaces are separators for the flags.

-Wall -Wextra -Werror -Wconversion -Wundef -Wdeprecated-implementations -Wno-unused-parameter -Wfloat-equal -Wimplicit-retain-self -Wnewline-eof -Wshadow -Wsign-compare
