Looks like all I needed to do was make it a class function. public class func getHello()

Turns out the person doing our builds was on Xcode 12.

To answer my own question, this issue was resolved by going to the Plist for the Watch Extension (important that it is the extension), and adding the item "App communicates using CoreBluetooth" to Required background modes.

I'm also interested in this method

_ .

Resolved, ignore this.

Ever resolve this?

I can confirm issue is in 14.1 (14B47)

Same error
