fixed project to build xcode5 ios6

[avishaan]

Build was failing in xcode5/ios6. This fixes the build error.

any particular reason you changed the license?

I didn't hear anything from you when I initially updated the xcode build to ios6 so I assumed you stopped supporting it and didn't want to keep your email address incase you didn't want that on your plate. I didn't mean that README to be included in the merge, just the commit c00v7c9

I just realized that you have been active on all aspects of this project, which is awesome! My focus has migrated off of iOS for the time being so I am willing to give you push access to the ancillary tools (apnagent-ios and apnagent-playground) since you have some great material. Since these are what are linked from the articles on apnagent it makes no sense to fragment the examples.

My one requirement is to have an email address for private communication for anyone who has push access to my repos. Can you email me via my GitHub profile address, then I can set you up.

The other thing I was thinking was to change the licence to WTFPL, as there is no reason for tutorial material to need any attribution. Thoughts?
