Swift SKShapeNode not accepting initialiser - swift

Question

I can't get the a sub class of SKShapeNode to accept an initialiser. To work around this I've tried to go by the example posted here Adding Convenience Initializers in Swift Subclass. The code i'm using is below.
class Ground1 : SKShapeNode {
override init() {
super.init()
print("Hello1")
}
convenience init(width: CGFloat, point: CGPoint) {
var points = [CGPoint(x: -900, y: -300),
CGPoint(x: -600, y: -100),
CGPoint(x: -100, y: -300),
CGPoint(x: 2, y: 150),
CGPoint(x: 100, y: -300),
CGPoint(x: 600, y: -100),
CGPoint(x: 900, y: -300)]
self.init(splinePoints: &points, count: points.count)
lineWidth = 5
strokeColor = UIColor.orange
physicsBody = SKPhysicsBody(edgeChainFrom: path!)
physicsBody?.restitution = 0.75
physicsBody?.isDynamic = false
print("Hello2")
}
required init?(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
}
}
When initialised the convenience init() is ignored and not used. Resulting in no shape being added to the scene. What am I doing wrong ?

Thanks to 0x141E, who roundabout pointed me in the right direction. I found this worked but the code looks messy. The reasons for going about the initialisation this way is explained in detail here Adding Convenience Initializers in Swift Subclass. Although I was thrown out of finding a solution because of the use of splinePoints and assigning to a path.
class Ground1 : SKShapeNode {
override init() {
super.init()
}
convenience init(name: String) {
var points = [CGPoint(x: -900, y: -300),
CGPoint(x: -600, y: -100),
CGPoint(x: -100, y: -300),
CGPoint(x: 2, y: 150),
CGPoint(x: 100, y: -300),
CGPoint(x: 600, y: -100),
CGPoint(x: 900, y: -300)]
self.init(splinePoints: &points, count: points.count)
lineWidth = 5
strokeColor = UIColor.orange
physicsBody = SKPhysicsBody(edgeChainFrom: self.path!)
physicsBody?.restitution = 0.75
physicsBody?.isDynamic = false
}
required init?(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
}
}
