I don't know where to start asking but here's some rough code what am I going to do

I'm just learning the Swift Decodable protocol and am running into a problem. I am able to decode one json object into a swift object, but am stuck with decoding an array.

What goes well:

imagine following json:

I have a string that is being set to a default when the input is outside of the specified values but it keeps returning null instead of the default value. what code am I missing to have the correct output?

I find that my integer and double values use the default correctly but my strings don't.

//This is a clip from my front end

My understanding of vtables is that, if I have a class Cat with a virtual function speak() with subclasses Lion and HouseCat, there is a vtable which maps speak() to the correct implementation for each Subclass. So a call

I was creating a function and forget to add all the instance variables in as arguments and it worked just fine, I thought that was necessarily, because I thought you were choosing what arguments in to inherit with that, but its seems to work with out it, so to reiterate, are they necessary and if so what purpose are they passed in for thanks
