Installing iOS SDK

Here are the steps I took to install the iOS SDK.

1. Checked my OS X version: I had 10.5 (Leopard)
2. Found my Snow Leopard DVD
3. Upgraded Leopard to Snow Leopard. I should have done this a long time ago.
4. From the same Snow Leopard DVD, I installed Xcode 3.2
5. Run Xcode
6. Realized that the Xcode in the DVD did not include the iOS SDK
7. Made angry noises
8. Downloaded the iOS SDK. The version 4.2 is about 3GB. It includes Xcode 3.2.5, and the OS X SDK as well.
9. Installed Xcode, iOS SDK, OS X SDK et al
10. Realized the iOS SDK will take up more than 8GB on my Macbook
11. Made incredulous noises
12. After installation, I ran Xcode, and created a new project. And yes, I was able to create an iOS application.
