title: appium fails to launch on iphone simulator
body: <p>I have the latest version of appium (1.4.0) on a mac. I'm trying to use the element inspector on an app. So, I tried to launch the app through my device but I keep getting an error saying could not initialize ideviceinstaller. So, I tried running it on the simulator. But, the app keeps crashing and i get the log message that DYShaderAnalyzerNextGPU is implemented in two locations. Then, a WebKit threading error and finally that Instruments exited with code 253.</p>
