When Quamotion runs tests on an iOS device, it uses some of the Apple Developer tools to perform key tasks. Examples of such tasks include installing or launching an application, and capturing screenshots.
These tools are not installed on iOS devices by default. They can be added to the iOS device by mounting the developer disk. If you run your app on a device using XCode, XCode mounts the developer disk for you.
Quamotion can mount the developer disk for you, but you need to install the iOS Developer Disk on your PC before Quamotion can mount it.
To install the iOS Developer Disk on your PC, you need to download it from a Mac machine and copy it to your PC. Follow these steps:
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupportfolder and create a zip archive that contains the contents of this folder.
