Deploying to iOS 3.1.3 device with Xcode 4

Question

How do I deploy to a iOS 3.1.3 device with Xcode 4?

Answer 1

1. Follow the steps in Ignacio's answer to install debugging support for iOS 3.x. (I think this is optional.)

2. Go to the project (not the target) Info tab. Change the iOS Deployment Target to 3.1 or earlier.

3. Go to the project (not the target) Build Settings tab. Change the Architectures to armv6. (Click on armv7 -> Press Other -> Press + -> Enter armv6 -> Press Done.

4. Go to Info.plist. Change the Required device capabilities' item 0 to armv6.

Answer 2

If you're using Xcode 4.2 (I don't remember the exact version on which support for iOS 3 was made on demand) you need to go to

Xcode -> Preferences -> Downloads  

and install support for the devices you require (3.0 - 3.2.2 and 4.0 - 4.1 show up on mine).

After you have done that just select your deployment target to 3.1.3 (or below) and you're good to go.

Answer 3

You set the Build Target to OS 3.0
