Today the PublicStaging directory errors occurred when the iPad had 5 GB and later at 6.5 GB free. In days past, building from the Mac, the iPad was down to < 200 MB and choked until I deleted a few GB. Seemed like just deleting apps wasn’t enough - needed a reboot.
I’m saying that the AFC connection errors that continue after transfer starts hints at a process not realizing the connection is ok. But I’m guessing and haven’t looked at any code.
Yes if I build a development package on Win7 and install via iTunes on the PC I get a good app installed to the iPhone and iPad. No Xcode on this machine for obvious reasons.
