You will be able to see Settings folder in your project in Xcode as shown in the screenshot below.

You can view Root.plist as ASCII property list or source code.

ASCII property list

Source Code

As you can see in Source Code... for every item in ASCII Property List(item 0, item 1 etc), there exists a dictionary in Source Code version. You can delete or add more dictionaries..according to your need.

<key>Key

<string>hostname

It is the key of one of the items in this case. You can fetch value of items stored in the dictionary as following

       NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
    NSString *hostURL = [[defaults stringForKey:@"hostname"] retain];
