For Xcode Beta : Apple actually admits something very like this as a bug in Xcode 9.3 beta. The release notes for beta 2 say: "The first time you trust a device, you may receive a message that the device cannot run executables for the device’s architecture. (35319190) Workaround: The error message is erroneous. Disconnect and reconnect the device."
