Hello,

I am a beginner learning to develop iOS apps with SwiftUI.

My setup:

  • MacBook running macOS 27.0.1
  • Xcode 27.1
  • iPhone 15 Pro running iOS 27.0.1
  • Developer Mode enabled on the iPhone

My iPhone is connected via USB-C and is recognized by Finder and macOS System Information.

However, my iPhone does not appear as a run destination in Xcode. Only simulators are available.

The command xcrun devicectl list devices detects the physical iPhone, but its connection information shows:

pairingState: unsupported

tunnelState: unavailable

I have already restarted both devices, tried different USB ports, checked my Apple account in Xcode, and confirmed that Developer Mode is enabled.

A simple SwiftUI test app runs correctly in the simulator, but I cannot install it on my physical iPhone.

What could cause this pairing problem, and how can I resolve it?

Thank you for your help.

Your versions should be compatible: Xcode 27.1 supports running apps on iOS 17 and later, so iOS 27.0.1 is within range. Seeing the phone in devicectl list devices doesn't necessarily mean Xcode has finished pairing it for development.

Open Device Hub from Xcode > Open Developer Tool > Device Hub. Select Physical Devices, choose the iPhone, and follow the pairing steps shown there. Keep it connected by cable and tap Trust if the phone asks. If it already appears as paired, Control-click it in the sidebar, choose Unpair, then pair it again. Apple's guide: https://developer.apple.com/documentation/xcode/managing-your-simulated-and-physical-devices-in-device-hub

If Device Hub still reports an error, could you share the exact message shown when you select the phone there, plus the iOS build number from Settings > General > About? That should help narrow down whether this is a pairing issue or an Xcode bug. Xcode 27.1 release notes: https://developer.apple.com/documentation/xcode-release-notes/xcode-27_1-release-notes
