Objective-C: Programming Foundations: Fundamentals (2011)
Objective-C: Programming Foundations: Fundamentals (2011)

Objective-C, which is based on the C language and uses a large library called Cocoa, is one of the older programming languages that is still being used today. Due to its age, Objective-C is more complex than languages such as Ruby and Python, but is still the language of choice for Apple applications. This Lynda.com online video will let you confidently approach a discussion of Objective-C, which is critical for developer and programming foundations.

Q: Using TextEdit with Mac OS 10.9 Mavericks? 

A: If you're using the built-in TextEdit program in Mavericks to write your first examples and your code doesn't seem to be working, here's one reason why: by default, "smart quotes" are now turned on in TextEdit Preferences.
 
This is where TextEdit will automatically change pairs of double quotes to "smart quotes" - where the opening and closing quote are different, like a 66 and 99.
 
While this is fine for human eyes, programming languages don't want this - when writing code, they need to be the plain, generic straight-up-and-down quotes.
 
So make sure that in TextEdit > Preferences, that "Smart quotes" are unchecked.
 
Important! Whenever you make a change to TextEdit preferences, make sure to then completely quit out of the program (Command-Q or using TextEdit > Quit TextEdit) and then re-open it, as changes won't take effect on documents you already have open.
 
However, we're not finished - just because you've changed the preferences, it does **not** change any *existing* smart quotes back to "regular" quotes - it just doesn't add new ones - so make sure to go through your files for any time you wrote quotes and TextEdit may have changed them to smart quotes - look in both the JavaScript, and your HTML too, and compare to the downloadable exercise files if necessary.
 
If that sounds like a bit of a chore, I recommend just downloading a code editor like Sublime Text (www.sublimetext.com) or TextMate (www.macromates.com) and using that instead of TextEdit - it's only a matter of time before you'd move away from TextEdit anyway - we only used it in the course because it was built-in and a quick way to get started, but it's now become more of a inconvenience than it was before.
