Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** +[NSString stringWithUTF8String:]: NULL cString'

[stigor]

Hello,

When I try to download bundle container with command:

ios-deploy --download --bundle_id <bundle_id> --id <device_id>

I got the error:

[....] Waiting for iOS device to be connected
[....] Using iPod Touch 5G 'ip39' (bde7bf06723d92f39ca160da99b350e20b1be23e).

I have the same problem. It seemed to start happening all of a sudden after upgrading to 1.7.0

Try providing a "--to" target. See README for an example.

During my tests on El Cap/Xcode 7, this feature no longer works. This function returns non-zero (code 12) now: https://github.com/phonegap/ios-deploy/blob/7ac9cdb10742a2b1d1855d7a70d684e4e062278d/ios-deploy.c#L1168
