With at least one (probably) native iOS application in our project pipeline, I thought this would be an excellent opportunity to be introduced in the world of Objective-C. Lacking almost any preexisting knowledge, I was a little surprised that the code not only looked unfamiliar from a Java developer's perspective, and that even with a C/C++ background this would take some getting used to.
The main concepts and differences are excellently explained in the syntax section on the Objective-C Wikipedia page.
It's also good to see that the language and libraries is being kept up-to-date with features like ARC (Automatic Reference Counting) to facilitate memory management.
For actual iOS development the Xcode IDE (only available for OS X) seems like an indispensable tool.
