Got 'GC capability mismatch' error when running ionic emulate ios


I followed the steps appear in “Getting Started” guide, and when running

$ ionic emulate ios

I get the following error:

2014-04-13 11:11:53.242 ios-sim[667:707] Error loading /Applications/ dlopen(/Applications/, 265): no suitable image found. Did find:

I have Xcode 4.6.3 installed and can’t upgrade to Xcode 5 since I have old macbook and can’t upgrade OS to 10.8 and above.


Seems like a issue related to your version of Xcode.
What version of cordova do you have installed just wonder?

$ cordova -v


I also suspect it’s the Xcode version, unfortunately I can’t upgrade to newer version as I mentioned, due to old hardware.

cordova version is 3.4.0-0.1.3


How about just trying to run from within Xcode itself? I personally don’t use ionic emulate ios. I just prefer to start and stop the apps in Xcode.


I’m new to Ionic so not sure how to do it… I simply followed the getting started guide. Is this approach documented somewhere ?


In your app directory, you’ll “platforms”, then “ios”. Inside “ios”, you’ll see something like “HelloCordova.xcodeproj” . Double click that. I will open Xcode. In the top left of the screen is a big “Play” button. Next to it is some text. Click that text to choose what device to simulate. If your device is plugged in, you can also run on a device. After you’ve selected a device/simulator, click the Play button.
