iOS Should a class have an array of the instances made of it?

[grandM]

I was fumbling around with an own class. I tried to let the class keep an array of all objects created with that class. For instance

class Wife {
var id: UInt
var existingWives:[Wife]?
init(){
if let _ = self.existingWives {
self.id = UInt(self.existingWives!.count) + 1
self.existingWives!.append(self)
} else {
self.id = 1
self.existingWives = [self]
}
}
}

This doesn't work though? Or is it a no go to enter an array of its owns objects within the class?

I solved it. Putting static before the array var made it a class variable. Not sure though if an class should hold an array of its own instances.
