There are two options here, as this occurs often when an iOS Release is done and Xcode is behind: For those who can install the beta or the release candidate that only works on MacOS Ventura: install the Xcode 14.3 RC 2 over the Software Downloads page (@America3D) pointed out direct link. This version includes the iOS 16.4 version. For those cannot install the newest Xcode version: Download the 14.3 RC2, "show the package contents" of the app (context menu on app-file or right click on file). Navigate to "Xcode-14.3.0-Release.Candidate.2.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/". Copy the 6.4 directory in the same directory for your current Xcode version.

You usually use the play(_:) method of WKInterfaceDevice to handle the vibrations as well as vibrate. For your case you could use WKInterfaceDevice.current().play(.click) to only vibrate. You can check out WKHapticTypes for when to use which one.
