Argument passed to call that takes no arguments - ios

Question

I am adding in a animated circle to a uiview. In this line of code:
var circleView = addCircleView(frame: CGRectMake(diceRoll, 0, circleWidth, circleHeight))
I am getting an error that reads "Argument passed to call that takes no arguments" pointing to CGRectMake.
I have aisles attached the rest of the code incase it is needed
import UIKit
import CoreMotion
import CoreGraphics
class Animation: UIView {
var circleLayer: CAShapeLayer!
override init(frame: CGRect) {
super.init(frame: frame)
self.backgroundColor = UIColor.clear
// Use UIBezierPath as an easy way to create the CGPath for the layer.
// The path should be the entire circle.
let circlePath = UIBezierPath(arcCenter: CGPoint(x: frame.size.width / 2.0, y: frame.size.height / 2.0), radius: (frame.size.width - 10)/2, startAngle: 0.0, endAngle: CGFloat(M_PI * 2.0), clockwise: true)
// Setup the CAShapeLayer with the path, colors, and line width
circleLayer = CAShapeLayer()
circleLayer.path = circlePath.cgPath
circleLayer.fillColor = UIColor.clear.cgColor
circleLayer.strokeColor = UIColor.red.cgColor
circleLayer.lineWidth = 5.0;
// Don't draw the circle initially
circleLayer.strokeEnd = 0.0
// Add the circleLayer to the view's layer's sublayers
layer.addSublayer(circleLayer)
}
required init?(coder aDecoder: NSCoder) {
fatalError("init(coder:) has not been implemented")
}
func animateCircle(duration: TimeInterval) {
// We want to animate the strokeEnd property of the circleLayer
let animation = CABasicAnimation(keyPath: "strokeEnd")
// Set the animation duration appropriately
animation.duration = duration
// Animate from 0 (no circle) to 1 (full circle)
animation.fromValue = 0
animation.toValue = 1
// Do a linear animation (i.e. the speed of the animation stays the same)
animation.timingFunction = CAMediaTimingFunction(name: kCAMediaTimingFunctionLinear)
// Set the circleLayer's strokeEnd property to 1.0 now so that it's the
// right value when the animation ends.
circleLayer.strokeEnd = 1.0
// Do the actual animation
circleLayer.add(animation, forKey: "animateCircle")
}
func addCircleView() {
let diceRoll = CGFloat(Int(arc4random_uniform(7))*50)
var circleWidth = CGFloat(200)
var circleHeight = circleWidth
// Create a new CircleView
var circleView = addCircleView(frame: CGRectMake(diceRoll, 0, circleWidth, circleHeight))
UIView.addSubview(circleView)
// Animate the drawing of the circle over the course of 1 second
circleView.animateCircle(1.0)
}
}

While I'd change all references of CGRectMake to CGRect, the issue is with the call to addCircle(). You didn't define any arguments.
Try changing things to:
func addCircleView(frame: CGRect) {
Or, since addCircleView looks like it doesn't use this parameter, try removing the CGRect/CGRectMake from the call to addCircle():
var circleView = addCircleView()
(It looks like you probably want the former.)
