The Big Nerd Ranch books are fantastic. Definitely check them out. I know they'll get something out for Swift sometime soon, but the iOS programming one would be a great foundation even with Objective-C as the sample code.
Some of the bootcamps will do financing. I'm against financing things that depreciate, but if you can get a decent job out of, it's not a terrible option.
-Stanford's Developing iOS Apps Course (free on iTunes U)
-developer.apple.com (unpaid account), gives you access to plenty of code examples to learn from and programming guides
-check out raywenderlich.com, objc.io, nshipster.com to name a few
-stackoverflow
-youtube(!)
-and if you can gather a few bucks, I'd recommend Big Nerd Ranch guide for Objective-C and the iOS programming version too
-IRC
Good luck!
