sounds like you opened the .xcodeproj file instead of the .xcworkspace file in xcode. even if thats not the case, simply saying "failed due to apple bug" gives zero information on how to solve your problem... but based on "missing web assembly" comment, my best guess is you opened the wrong file.
i know this is an old comment but in case others have the same question in the future, here is what you need to know :)
1. first of all, public_html and the www folder are usually the same - public_html directory will be a shortcut to your www directory or vice versa. this is known as your websites "root" directory. dont worry about the cgi_bin folder. or any others that are not located within your public_html (www) folder unless you are changing your server configurations and know what you are doing.
2. if you upload your php file to your public_html (www) folder, your file will be accessible from yourdomain.com/login.php
3. personally, i would add an additional directory ie "login" inside of my root directory so resulting directory structure would look like www/login, then add my php file in there. this will make your file accessible at yourdomain.com/login/login.php
hope this helps
