I built and run an iPhone application on iPod Touch 2.2.1 device, got some problems and made a fix attempt. Now trying to re-build & run the application gives two (2) error popup notes:
Could not receive a message from the device [OK]
Google couldn't find this! The device itself is working happily, I can even launch and use the app I'm trying to install. iTunes looks like it's still connected... What could be the problem?
I was having the same issue, and it was due to having old WiFi connection settings. I just connect new WiFi in both iMac and iPhone. I never connect via USB. iMac automatically connects to my iPhone and I can debug directly on my iPhone. Sometimes the connection is loose; in that case, I just go to
-> Windows -> Device and simulators -> select my device -> right click -> connect vai IP address.
Just enter an IP address from my iPhone WiFi. For that, just go to --> WiFi of iPhone -> info (symbol) -> IP address.
I also got this messsage, the problem was too many devices (via USB) connected to my MacBook Pro.
