Some additional info, ive now also tested using the exact instruction they have at the end of their document where they say “Before uploading, test your simulator build by running ios-sim launch <path to .app> and verify that the app opens in the simulator.”
It took me a while to figure out how to do that (im not very familiar with mac’s). For anyone else that wants to know, you need to install some stuff to make it happen.
First install HomeBrew by opening Terminal and pasting the below
ruby -e "$(curl -fsSL https://raw.github.com/Homebrew/homebrew/go/install)")
Then it says to run “Brew Docotor” from the terminal before installing anything, so i did that, not sure what that does exactly.
The you can install ios-sim using homebrew from the terminal by doing
brew install ios-sim
That makes the ios-sim command line tool available, looks like it just links to the xcode ios simulator
Then you can test your app using their exact steps. Just use corona simulator to Build for iOS, set the target to “iOS Simulator”, it will build and load the ios simulator. Exit the ios simulator. In the terminal, change into the directory where corona is putting your build files (ie your .app folder). For me it was the desktop. So from the terminal, while in the desktop folder (in my case), just type as it says
ios-sim launch mygame.app
where mygame.app is the name of the your game. Looks like it pretty much does the same thing as just building for simulator in corona, but to be sure i did this so i was 100% sure it was working as per FB’s instructions. I am about to submit again, but i dont hold out much hope because i just submitted the simulator build the first time and they rejected it with the message the original poster mentioned. <sigh>
