How to create a node in another node - ios

Question

I have a circle, an SKShapeNode, and I want to create a child node inside it. How I can do this?
func AddCircle() {
Circle = SKShapeNode(circleOfRadius: circleRadius)
Circle.position = CGPoint(x: self.size.width/2, y: self.size.height/2)
Circle.strokeColor = UIColor.whiteColor()
self.addChild(Circle)
Circle.addChild(BooCharacter)
}
Main Character:
func AddCharacter() {
BooCharacter.size = CGSize(width: 30, height: 30)
BooCharacter.anchorPoint.y = 0
BooCharacter.zRotation = CGFloat(-M_PI_2)
BooCharacter.position.y += circleRadius
}
I want to create an object in my circle but I don't know how you write it.
For example, I've tried to add a rect inside of my circle:
func AddRect() {
Rect = SKShapeNode()
Rect.path = UIBezierPath(roundedRect: CGRect(x:0, y: 250, width: 256, height: 256), cornerRadius: 64).CGPath
Rect.fillColor = UIColor.whiteColor()
}
func AddCircle() {
Circle = SKShapeNode(circleOfRadius: circleRadius)
Circle.position = CGPoint(x: self.size.width/2, y: self.size.height/2)
Circle.strokeColor = UIColor.whiteColor()
self.addChild(Circle)
Circle.addChild(BooCharacter)
Circle.addChild(Rect)
but it's still not working.
I want to create and add triangles inside of my circle like this

You're doing exactly the right thing, although I don't see where BooCharacter is being created – are you definitely creating that somewhere? Using addChild() to add a node to your scene, or to add one node to another node, is correct, and should work for all types of SKNode.
