If i create a Class and say that it's a subclass of a OvalShape, that class will not extend the OvalShape class?
For example, my new class it's called OvalShape_ext, subclass of OvalShape.

var oval=OvalShape_ext();

why i can't access for example oval.frame.x

Bump: Also interested in this.

Started exploring the class object.
My simple test:

Add class object, name it "specialView", and set it's subclass to View
In a button action add:

const test= specialView()
test.backgroundColor = Color.red
test.frame = Rect(0,0,100,100)
View1.addSubview(test)

Expected result:
New view created inside View1
Actual result:
Error " Unable to find backgroundColor into class specialView"

@Marco I'm actually skipping :-)
