Cannot find 'CLKComplicationServer' in scope

Hi

I imported my project into Xcode 12 Beta and it seams okay except for a few things. am getting an error from a function to reload the complications.

in my ExtensionDelegate.swift file

Code Block 
func reloadActiveComplications() {
	print("Reloading Active Complications")
	let server = CLKComplicationServer.sharedInstance() //Cannot find 'CLKComplicationServer' in scope
	for complication in server.activeComplications ?? [] { server.reloadTimeline(for: complication)}
}

Im looking at the documentation here Creating and Updating Complications and trying to find the answer.

The code Apple uses on that page is

Code Block 
let server = CLKComplicationServer.sharedInstance()
		for complication in server.activeComplications ?? [] {
				server.reloadTimeline(for: complication)
		}

Looks the same to me. Can anyone tell me why this might be?
