Why am I unable to subclass the SKSpriteNode - swift

Question

Forgive me, I might have asked this before, but it hit me in a different manner, and am still learning Swift
In my main scene I can easily initialize a node and then manipulate it as I like:
let myGSlot = SKSpriteNode(color : .green, size: CGSize(width: 100.0, height: 100.0))
However when I try to subclass it:
class GuessSlot : SKSpriteNode{
init(color: SKColor, size: CGSize) {
super.init()
}
required init?(coder aDecoder: NSCoder) {
fatalError("init(coder:) has not been implemented")
}
No matter what I do, the editor gives me many errors. The main one being:
Must call a designated initializer of the superclass 'SKSpriteNode'
Whether I put it in init() or super.init()
I know I'm new to Swift, but this is killing me!
********* latest update and the only way I can get it to compiles but still crashes with the error:
Thread 1: EXC_BAD_ACCESS (code=2, address=0x7ffeec64aff0)
In the debugger I can see that zero values are coming in for the parameters
convenience init(color: SKColor, size: CGSize) {
self.init(color: color, size: size)
}
I do feel less stupid when I see all the threads out there with confusion over this info

Answer 1

In Swift, you need to call an initializer that is implemented directly from your super class, in this case, SKSpriteNode. super.init() is implemented by another class that is in SKSpriteNode's inheritance tree, like SKNode or NSObject. You can always check the documentation for which constructors can you call for each class. It's very important to pay understand that you need to call designated initializers in your subclass
For example, you can do
class GuessSlot : SKSpriteNode{
init(color: SKColor, size: CGSize) {
super.init(texture: nil, color: color, size: size)
}
required init?(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
}
}

I am not sure where the disconnect is, but as mentioned in the comments, you just needed to override the proper designated init texture, color,size.
class TestSpriteNode : SKSpriteNode{
required init?(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
}
override init(texture: SKTexture?, color: UIColor, size: CGSize) {
super.init(texture: texture,color:color,size:size)
}
}
This will get you access to all of the inits of your parent class.
You will now be able to do var s = TestSpriteNode(color:.red,size:CGSize(width:1,height:1))
If you need to override this convenience init, you need to refer to one of the designated inits you overrode, not the convenience init.
class TestSpriteNode : SKSpriteNode{
required init?(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
}
override init(texture: SKTexture?, color: UIColor, size: CGSize) {
super.init(texture: texture,color:color,size:size)
}
convenience init(color: UIColor, size: CGSize) {
self.init(texture: nil,color:color,size:size)
}
}
