xCode Error with iOS 8.3 Device

[Scott Rossi]

I get this error when trying to copy an LC standalone onto my iPhone 5
running iOS 8.3:

The Developer Disk Image could not be mounted.


Trying the few options found on the web (more recent xCode, restarting the
phone) hasn't solved the issue.  Anybody run across this one before?

OS X 10.9.5
xCode 6.2
LC 7.0.4

Thanks & Regards,
