iOS Unknown Deployment Platform error

A couple things to check.

First, make sure you've pointed LiveCode to your Xcode app bundle. I'm assuming you've already done this. Otherwise, the Test option wouldn't even be available to you. But I just wanted to make sure.

Second, make sure you've selected the appropriate simulator version from the Development -> Test Target menu in LC. I find that sometimes I have to reset this after upgrading LiveCode and/or Xcode. If for some reason you don't have the simulators you want, launch Xcode, open Prefs -> Downloads, and download the additional simulators. With Xcode 4.5 you can go back to iOS simulator 5.0.

Hope that helps you.
