macOS Version 13.4.1 (Build 22F82) Xcode 15.0 (22181.22) (Build 15A5161b) iPhone SE running iOS 17.0 beta I have a test device (iPhone SE) with iOS 17 beta installed. I am using a cable to connect it to my MacBook. Within Xcode beta, I am using the "Devices and Simulators" dialog. Attempting to "connect" the device fails repeatedly with the following message: The developer disk image could not be mounted on this device. Domain: com.apple.dt.CoreDeviceError Code: 12040 Failure Reason: Error mounting image: 0xe8000106 (kAMDMobileImageMounterCredentialsFailed: AppleConnect authentication failed or was cancelled.)

Restarting the iPhone. Logging in/out from iCloud on the iPhone. Logging in/out of Apple Developer within Xcode. Restarting my MacBook. Burning sage and making an incantation.
