Great thanks for the quick reply - will give that a go. whilst I’m on the topic - is there a way to run preview on Simulator ie not build/run full version but similar to preview on my real device, I’d love to be able to do the same with Simulator so I have a bit more freedom for window placement/sizing etc

Really appreciate the extensive answer. I’ll have a go with this later! I was thinking to approach this as “make it work with swift 6” rather than ignore the errors so thanks for the direction will see how this goes and report back
