I'm talking of model objects that serializes certain properties (not
necessarily all) that should have their setter be private/hidden for
encapsulation reasons:
struct Person {
private(set) var birthdate: NSDate
}
I'm not a fan of adding an attribute like private(reflectable). The proposal we
are discussing is most probably coming post-Swift3 and we might as well wait
until property behaviour a are brought in to the mix.
Sorry if my post feels negative, but I'm a huge supporter of Reflection APIs
and I just want us to get it right :)
