Xcode/Swift error that makes no sense: Unknown type 'CGFLoat'. Did you mean 'CGFloat"? [closed]

Question

Xcode Version 13.0 beta 5 (13A5212g)

In a struct definition: var value: CGFloat = 0.0

Get the error: Cannot find type 'CGFloat' in scope; did you mean to use 'CGFloat'?

What am I missing?

The first line of this swift code file is: import Foundation.

In the documentation it seems that CGFloat is in the Foundation unit.

Answer 1

What is imported into this file?

I suspect either

(a) CGFloat isn't imported but XCode is being 'helpful'

or

(b) CGFloat has been defined twice somewhere.

My money is on (a). CGFloat is part of core graphics, pulled in with UIKit so you need #import <UIKit/UIKit.h> somewhere in there.
