Xcode error: Failed to launch simulated application

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 a

Answer 1

This ends up being a product name issue:

The fix is to revert back to

${EXECUTABLE_NAME} ${PRODUCT_NAME}

for the executable file and com..${PRODUCT_NAME} in the info.plist.

Clean XCode, Quit, rese and quit simulator and you're good to go.

Answer 2

Is your CPU Intel, and, of a model distributed in Apple hardware?

I doubt the Simulator will work reliably (if at all) on non-Intel CPUs and/or in VMWare. The simulator is very CPU specific in order to reflect the arm hardware of the iPhone.

The SDK ONLY supports Intel hardware from Apple.

There is a significant effort involved in creating the simulator and it's not easy or cheap (read, thousands of man hours) to support every CPU.

This was bugging me too but finally got it working. Unfortunately, I can't reproduce what I did it but here's my list of actions for your information.

The project causing the problem was one I'd downloaded from Apple and tweaked. Interestingly, I could still launch my own projects fine.

So, here's a list of actions that I did (note that none of the actions below worked just by itself): - closing the simulator and doing "clear file history" - restarting simulator - rebooting - restarting xcode - resetting the iPhone with Reset Content and Settings

However, by the time I'd tried all of the above with a fresh version of the code I'd downloaded - it was working again. Just out of interest, I dragged the project that was causing this problem back to the desktop and it was OK now.

Answer 4

I had the exact same problem - I reset the iphone simulator and then quit the simulator then started it again.

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.
