5/3/26. MacOS Tahoe 26.3.1 XCode 26.4.1 ISSUE: Problem connecting my iPhone to XCode. My Apple watch connects but not my iPhone. My iPhone is a Model 12 Pro Max. I have it connected to the Mac Mini via a cable. The iPhone shows up in Finder. Xcode reason for inability to connect is a previous preparation error: "The tunnel connection failed while the system tried to connect to the device”. WHAT DID NOT WORK: Restarted Mac & iPhone. Plugged and unplugged cables. Deleted Derived Data folder & Provisioning Profiles data and then restarted XCode. WHAT DID WORK: Settings>Developer>Networking…toggle on Network Link Conditioner…Test Responsiveness Result was almost immediate…Device disappeared and then reappeared in XCode under Devices and Simulators fully operational…no reboot or repairing needed.
