Merge multiple CGPaths together to make one path

Question

I am making a complex shape using a few CGRects and Ellipses. I would like to stroke that path once it has been created. When I stroke the path it strokes each shape. Is the

Based on the answer of Thomas Zoechling

For swift3

height = self.bounds.size.height
let thirds = self.height / 3

let aPath: CGMutablePath = CGMutablePath()
let rect = CGRect(x: (58 - 10) / 2, y: 46, width: 10, height: self.height - 58)
aPath.addRect(rect)

aPath.addEllipse(in: CGRect(x: (58 - 48) / 2, y: 0, width: 48, height: 48))
aPath.addEllipse(in: CGRect(x: (58 - 48) / 2, y: thirds, width: 48, height: 48))
aPath.addEllipse(in: CGRect(x: (58 - 48) / 2, y: thirds * 2, width: 48, height: 48))
aPath.addEllipse(in: CGRect(x: 0, y: self.height, width: 48, height: 48))
aPath.closeSubpath()

let other: CGPath = aPath.copy(strokingWithWidth: 12, lineCap: .round, lineJoin: .round, miterLimit: 1.0)
let square = CAShapeLayer()
square.fillColor = UIColor(red: 36/255.0, green: 56/255.0, blue: 82/255.0, alpha: 1.0).cgColor
square.path = other
self.layer.addSublayer(square)

let square2 = CAShapeLayer()
square2.fillColor = UIColor(red: 50/255.0, green: 70/255.0, blue: 96/255.0, alpha: 1.0).cgColor
square2.path = aPath
self.layer.addSublayer(square2)
