You also have to pay $100 a year to be in Apple's Dev program to be able to actually test it on an iOS device instead of just the simulator.
you can try out simple objective-c stuff at http://ideone.com/ but nothing like an iOS app.
The newest Xcode supports swift as well.
example code to look at (via google search for ios example apps):

Im thinking about becoming a developer for iOS and I need a site a) that can give me apps to edit and b) A decent Script editor (for free) that can let me programme in the Objective C Coding language.
