You'll need Objective-C for both Cocoa (Mac) and Cocoa Touch (iOS). Though you are right that C++ code can be compiled to run on Mac in many instances. But for native Mac/iOS programming most of it is done in Obj-C these days.
See also Xcode, GCC, and Homebrew[^] for some new ways to code without relying so heavily on Xcode.

Must-have Tools for Developers on Windows (source: DZone)
Beware of programmers that carry screwdrivers.
"Every dev has his favourite list of tools, applications and OS which they believe are indispensible and without them they would not be able to develop anything. Here’s my list."

Forgetting the Operating System (source: ONE37)
Unified alerts: novelty, annoyance or a sign of an OS-less future?
"It's no longer about OS X or iOS, but about the user's interactions, the seamless experience, and the forthcoming marginalization of the operating system."

Microsoft Office for iPad: Separating fact from fiction (source: ZDNet)
Microsoft believes it has a ‘great tablet experience with Office'... but which tablet?
"The folks that brought us last year’s rumor that Microsoft planned to deliver Office for the iPad in 2012 are back with an update. Is it any more likely this time around?"

Don't cheat with the user interface (source: Jimmy Nilsson)
The user interface has always been important, but has often been treated as the poor relation.
"The success of an application largely depends on the user experience. But it doesn't happen by itself that the UI code becomes good. In fact, it's often the opposite."

What Can You Do with .NET Gadgeteer? (source: Devhammer's Den)
Build small electronic devices using the .NET Micro Framework and Visual Studio.
"The cool thing about Gadgeteer is the speed with which you can come up with and execute on your ideas. You can build something fun or practical, prove out the concept, and then pull it all apart again and build something else."

In defense of doing it the “hard way” (source: accidental/ninja)
Learning to code is not the same as learning to write applications.
"The only way to learn something properly is the hard way. The only way out is through. I recommend trying to build something that you want to see made as your first project."
|
|
|
|
|
The method that’s worked best for me, and that I recommend to anyone starting out, is to try to build something that you want to see made as your first project.
When I started out, programming for Atari ST, I asked other people what they wanted to see. I got good ideas, good feedback, and a loyal customer base (until Atari started to unravel and I got out of there as quick as I could).
Other than that, I think the blog is spot-on.

Designing Calm Technology (source: Mark Weiser and John Seely Brown)
Some wise thinking on technology and UX... from Xerox PARC in 1995.
"Designs that encalm and inform meet two human needs not usually met together. Information technology is more often the enemy of calm. Can we really look to technology itself for a solution?"

The iPhone monoculture (source: QuirksBlog)
Web developers don’t care about WebKit. They care about the iPhone.
"Webkit monoculture: threat or menace? This is simplistic us vs. them thinking. It’s not helpful. Now if you would say there’s an iPhone monoculture among web developers, you’d be right. But whose fault is that?"

Enterprise devs: tablets are your future. Deal with it.
"The end-user, and “the man” are going to demand Tablets. Those developers who resist will learn their true place in the hierarchy. And it’s not at the top."
