SDKs for iPhone

Open Toolchain

Open Toolchain [1] is for the development of 1.x native application for iPhone, It can be used in Mac OS X (Intel/PPC) 10.4/10.5, Linux, Cygwin or MinGW. This SDK uses gcc cross compiler for the development.

Build from sources method:

• http://code.google.com/p/iphone-dev/wiki/Building for Mac OSX 10.4 (PPC/Intel) / Ubuntu / Fedora / Gentoo / Debian / CentOS / XP Cygwin / XP MinGW


• http://wikee.iphwn.org/howto:toolchain_on_leopard for Mac OSX 10.5 Leopard
  

There are also Pre-build Binary for different Operating System (OS) and CPU

iPhone SDK

iPhone SDK is the offical development tools from Apple Inc for iPhone Developer to develop firmware 2.0 Native Application. It is only available for Mac OS X 10.5.2 and Intel CPU (see ppc hack here).


The latest iPhone SDK beta 8 can be downloaded from Apple iPhone Developer Website,
Previous version of iPhone SDK can be downloaded from this ftp site. After installation of the iPhone SDK, all the sample codes of that version of SDK can be obtained from harddisk. They are in

/Developer/Platforms/iPhoneOS.platform/Developer/Documentation/DocSets/com.apple.adc.documentation.AppleiPhone2_0.iPhoneLibrary.docset/Contents/Resources/Documents/samplecode

There are numerous limitations [2] for iPhone SDK in development of official iPhone software, Therefore iPhone Dev Team provides a how-to use iPhone SDK with Open Toolchain API


It is now also possible to build firmware 2.0 app without using the official sdk and Mac OS. Read this article - Upgrading the iPhone Toolchain


Apple Inc has also provided iPhone Web Application documentation, but it is less attractive than Native Application.
