var posinonY:Float = Float(y) + Float(pipeDown.size.height) + Float(verticalPipeGap)
pipeDown.position = CGPointMake(0.0, Float(posinonY))
I get this error:
"NSNumber' is not a subtype of 'CGFloat'"
Why?
CGFLoat need double type
pipeDown.position = CGPointMake(0.0, Double(posinonY))
this is ok.

Swift version: 5.6. A CGFloat is a specialized form of Float that holds either 32-bits of data or 64-bits of data depending on the platform. The CG tells you it's part of Core Graphics, and it's found throughout UIKit, Core Graphics, Sprite Kit and many other iOS libraries.
Available from Swift 5.5 SE-0307 introduced a small but important quality of life improvement: Swift is able to implicitly convert between CGFloat and Double in most places where it is needed. Swift implements this by inserting an implicit initializer as needed, and it will always prefer Double if it's possible.
Rounding Numbers in SwiftBy using round(_:) , ceil(_:) , and floor(_:) you can round Double and Float values to any number of decimal places in Swift.
Type Aliases The native type used to store the CGFloat , which is Float on 32-bit architectures and Double on 64-bit architectures.
Use CGFloat(number) instead of Float(number)
pipeDown.position = CGPointMake(0.0, CGFloat(posinonY))
Since CGFloat is not a Double on 32bit, it becomes hard to use CGGeometry and frameworks like CoreGraphics or SpriteKit. This library makes it a little easier and hopefully Apple takes care of it soon.

But if you want to just make it work without dependencies use var myFloat:CGFloat explicitly, and make sure to cast any Double (numbers that are type inferred) to CGFloat
2.0 is inferred to be a Double and won't play along with the CG-Structs on 32bit.
