Add settings to 4 Wowonder xamarin apps

The apps have already been written, I want the settings added in these apps (api key from server, small settings in the [login to view URL] files of the apps) and to ensure they all can build correctly. You will not be writing the apps, as source will be provided to you, you will simply be ensuring no errors occur when they compile. Also, since I do not have a macintosh, the freelancer acceptinng this job will compile the iOS apps that are provided to ensure the ipas can be added to the app store. I will be submitting the apks and ipas to the respective stores. Be advised, this will require NO access to any part of my server.
