Why not just use didSet and willSet?
@jrg.developer Can you please help with this when you get a chance? Thank you - much appreciated! :]
You could accomplish a similar result by overriding these! However… 
- You’d write more code
- You’d have to take care of one-to-many mappings yourself, including memory management (preventing strong-reference cycles, etc)
- You’d have to worry about testing, maintaining, etc the above
When you have a first-party solution that’s provided for you already that does all of the above, why not just use it?
