How can I develop iPhone apps and iPad apps on the same machine?

Question

It looks like in the future we can just use the non-beta version of the iPhone SDK for development right away.

But for now, the only way to develop an iPad is to use the beta version of SDK 3.2. However, if I install this, Apple clearly states that I should not send applications to the application store with it.

I am an independent developer with one machine. Is there a way to continue updating existing apps for the iPhone while continuing to develop for the iPad?

Answer 1

The best way to do this is to install the beta version 3.2 SDK in a place other than '/ Developer'. In the "Custom Macintosh HD Installation" section, select "Other" from the "Pop-up" button and specify the installation somewhere like: "/ Developer-Beta".

You can then launch Xcode from / Developer / Applications for your iPhone applications and Xcode from / Developer -Beta / Applications for your iPad applications.

Answer 2

If I read the agreement correctly, the ban on sending apps with beta version 3.2 applies only to the SDK, not to the tools. If you install the SDK for the application database in the SDK earlier than 3.2 (which probably already exists anyway), you can build using the SDK 3.1 and earlier by selecting them from the Browse menu in Xcode.

I introduced updates to my iPhone apps built with SDK 3.0 using 3.2 beta tools and they were accepted without any problems. Until you build a new SDK, you should be fine.

EDIT: I don't work for Apple, I'm not a lawyer, blah blah. But it worked for me, and the warning only says “iPhone SDK 3.2”. Xcode tools are not mentioned.

Answer 3

If you install 3.2, the Active SDK menu looks like

However, in the project settings, you can change the SDK as follows:

Thus, you can develop for any version of the OS using the same computer, etc.
