No 'clamp' candidates produce the expected contextual result type 'CGFloat'

Question

I explicitly cast the type between them, but the error is still there

 var destX:CGFloat  = 5.0

func clamp(value: CGFloat, min: CGFloat, max: CGFloat) -> CGFloat {
if value > max {
    return max
}
else if value < min {
    return min
}
return value
}

 override func update(_ currentTime: TimeInterval) {


let ballRadius: CGFloat = 10
destX = simd.clamp(destX, min: ballRadius, max: frame.width - ballRadius) as CGFloat
let destXAction = SKAction.moveTo(x: destX, duration: 0.1)
self.main.run(destXAction)

Here is the code

Obviously it does **not** otherwise you wouldn't get an error — vadian, Dec 24 '18 at 20:42
I don't know, I'm not familiar with this stuff. How about reading the documentation? — vadian, Dec 24 '18 at 20:49

Having a look here, I can't see an overload that takes a CGFloat. simd.clamp takes either, float2, float3, float4, double2, double3 or double4.

To use your func clamp(value:, min:, max:), call it this way :

destX = clamp(value: destX, min: ballRadius, max: frame.width - ballRadius)

Use of 'clamp' nearly matches global function 'clamp(_:min:max:)' in module 'simd' rather than instance method 'clamp(value:min:max:)' – Dakata Dec 24 '18 at 20:39
Use 'simd.' to reference the global function in module 'simd' – Dakata Dec 24 '18 at 20:39
@Dakata prefix it with the name of the module you're in or change its name – ielyamani Dec 24 '18 at 20:45
