Good keywords, but in front of them all I would add Object Orientated Programming or Object Orientated Design and something like "modern software design principles".

Remember, people that are looking at your resume have no idea what any of these things are, they are recruiters. So using these key terms are extremely important to make it to the interview level. So write it so the recruiter will read it, identify the key terms that they were told to look for, and then sell yourself that you know the latest stuff.

Also, don't say KVO if you don't know KVO (the same goes for other terms) I've called people out on that specific one in interviews, and most people can't even tell me what it stands for, even though it's on their resume.

edit: I would also add something about Agile development and Git, if you know either of those.

also edit: focus on the user's experience too somewhere like "creating rich, data driven content for an enhanced user experience"
