Requirements

The SDK is available for free: developer.apple.com

An Intel-based computer running Mac OS X is required for development

Deploying applications to a device requires a $99 yearly subscription to ADC

Applications must be approved by Apple, and they keep 30% of all proceeds


Objective-C

Objective-C is a thin, fully object-oriented layer on top of C. Easy to pick up if you know Java.

Used for ALL high-level APIs in Mac OS X and iPhone.

Modern OO concepts: dynamic messaging, introspection, dynamic class extension...


Objective-CAll C code is still valid Objective-C. GCC can compile C, C++, and Objective-C at the same time so projects can utilize all three languages.

Like C, Objective-C assumes you know what you’re doing:

Liberal type coercionSparing use of exceptionsDuck-typed (“If it looks like a duck, acts like a duck, and quacks like a duck, it’s a duck”)


Tools

iPhone developers get to use the same tools designed for writing Mac OS X apps: XCode and Interface Builder.

Read: Desktop-quality tools targeting a mobile platform!

Incredible suite of analysis instruments: CPU and OpenGL profiling, leak detection (on the phone!)
