Answer 1

FIXED For the issue: iPhone Simulator failed to find the process ID of com.yourcompany.[your application name]

I was having an issue building and simulating a project I built under OS Version 2.2.1, which I could no longer get to build and run in the simulator for XCode 3.1.4, even though I forced XCode to build for "Simulator - 2.2.1 Debug"

I was able to get past this problem by: - Close the iPhone Simulator - Putting XCode into View->Detail - Opening the "Info.plist" file in the "Resources" folder - Near the top of the file you should see "Info.plist" with and up/down arrow selector - Click on the up/down arrow selector - Select "Clear File History"

Built For: Simulator - 2.2.1

XCode Version: 3.1.4 (Which includes OS3.1 Beta 3)
