Conversion Type Error CGPoint to CGFloat in Swift

   var _deltaTime = NSTimeInterval()

   var _pointsPerScndSpeed = Double()

   var bgVelocity: CGPoint = CGPointMake(_pointsPerScndSpeed, 0.0)

      //Cannot convert the expression's to type 'CGFloat'

     var amToMove:CGPoint = CGPointMake(bgVelocity.x * _deltaTime, bgVelocity.y * _deltaTime)

       //Could not find an overload for '*' that accepts the supplied Arguments

The members of CGPoint have the the type CGFloat, which is a Float on the 32-bit architecture and Double on the 64-bit architecture. Swift does not implicitly convert types. You can either use CGFloat consistently in your code, or add explicit casts:

var bgVelocity: CGPoint = CGPointMake(CGFloat(_pointsPerScndSpeed), 0.0)
var amToMove:CGPoint = CGPointMake(bgVelocity.x * CGFloat(_deltaTime), bgVelocity.y * CGFloat(_deltaTime))
