I'm running a project in {N} 5.1.0. Recently I've been having a semi-recurring issue when attempting to run on a physical device using tns run ios. The error message is:
Unable to apply changes on device: path/to/project/platforms/ios/build/device/funfanglemobilepos.ipa on device with identifier undefined. Error is: Device 00008020-000418E936D8002E lost during operation install for message 53e1b992-66b6-41f8-96bf-c81b74d63915.
It works fine when I run directly from Xcode or when I run on an emulator and it doesn't always happen. Sometimes I'll be able to run on my physical device and it will get this error when I change some code.
I've run tns doctor and it seems like everything is fine with my setup. Any ideas?
The solution for me was to try a different cable, just like Narendra commented above
