iPhone is not available. Please reconnect the device – Dev

I’m on iOS 13.5 and using Xcode 11.4 to build on to it. I’m getting this error message:

enter image description here

The KBlackberry is my iPhone device name.

I tried restarting the device and reconnecting of course and various other things but nothing seems to fix it. My next step is to try a newer version of Xcode.


Xcode 11.4 includes SDKs for iOS 13.4 as mentioned on the release notes

You must update to the beta version if you wish to deal with iOS 13.5.


Before you debug with iPhone, follow this mapping table about the version of Xcode and iOS:

Xcode 12.3 → iOS 14.3

Xcode 12.2 → iOS 14.2

Xcode 12.1 → iOS 14.1

Xcode 12 → iOS 14

Xcode 11.7 → iOS 13.7

Xcode 11.6 → iOS 13.6

Xcode 11.5 → iOS 13.5

Xcode 11.4 → iOS 13.4

If you’re still encountering the error, try to unpair the device within the menu Window > Devices and Simulators, clean Xcode, reconnect and trust the device, then re-run. It worked for me!

  4. Scroll down on the right side and see the error

  8. Unpair your phone from windowsDevices and Simulators.
  9. Pair your iPhone
  10. Enjoy
