I am trying to deploy a new version of my iOS app via Xcode to an iOS 15.4.1 Iphone 6s with Xcode 13.1 installed but get the error:

Failed to prepare device for deployment
If you are certain that Xcode supports development on this device, try disconnecting and reconnecting the device.

Is this error occurring because I am using Xcode 13.1 with iOS 15.4.1 and need to upgrage to Xcode 13.3 instead? Any Ideas?

That's correct. Xcode 13.1 preceeded the release of iOS 15.4.1 by several months, so it does not know how to work with devices running something that didn't exist at the time Xcode 13.1 was released. You need to upgrade to Xcode 13.3. The supported pairings of iOS version to Xcode version are documented on the Xcode Support page.

Yes.

The following article provides more details and workarounds if you're unable to update to Xcode 13.3:
