Xcode error: Failed to launch simulated applicatio

Question

Problem

Unlike people have asked at here and here, I got this error after a brand new installation of Leopard (hackintosh), this problem really driving me crazy and nowhere else to find an clue, I googled and visited every article related with this, still can't get it solved.

After the first time install iPhone SDK 2.2.1, start a new project(any type, Navigate based, OpenGL ES application), then build and go, I got the following problem: sometime it's:

Failed to launch simulated application: Unknown error.

and sometimes it's:

Failed to launch simulated application: iPhone Simulator failed to find the process ID of com.yourcompany.[application name]

It seems that apps in the simulator crashed immediately, so Xcode can find the process ID.

Solution

This link says that this even can't be solved. Some others make a detailed step by step:

1. Uncheck Info.plist
2. Quit XCode
3. Delete directory /Lib/Caches/com.apple.DeveloperTools.###
4. Open Xcode project
5. Clean All Targets
6. Rebuild

and I reset the iPhone Simulator. This also didn't solve the problem…

I've even tried uninstall the SDK and reinstall it, still got the same error…

Is this a problem related with hardwares? or the operating system version? I'm using a hackintosh (iDenebv1.4 10.5.6), all other software works good including iTunes && vmware fusion.

Great thanks for any further tips or clues!

Answer 1

I had the same problem. I had accidentally added my info.plist file to my target and it was getting copied to the app bundle every time I built the application. So there were 2 .plist files in the bundle - mine and the Info.plist, created by XCode - which confused the simulator.

Answer 2

I fixed this problem by removing the "Icon already includes gloss and bevel effect" property from the Info.plist file in my project.

Answer 3

Wow, what a pain. I had to uninstall XCode 4 via the command line and then install XCode 3 again. Make sure that you restart after you reinstall. Working...

Answer 4

I had the same problem, I fixed it by launching the simulator through another app and deleting the app I was trying to run on it. Then try to build and run and worked perfect.

Here is a discussion about how to run app in simulator via command line, hope it helps to understand how does xcode and simulator works.

But I didn't work it out.

Well, I "solved" it by install another distribution of hackintosh(IPC 10.5.6), works perfect!

Answer 6

My fix:

restarted the Mac and it was fixed. (before that tried clearing caches, deleting caches from iPhone Simulator, cleaning, rebuilding, quitting OS, quitting Simulator, nothing worked.) Restarting the OS worked.
