userinfo-representable
helps a conversion from userInfo
to your types.
Define your types with attaching @UserInfoRepresentable
.
Like this example, @UserInfoRepresentable
can be nested.
@UserInfoRepresentable
struct Foo {
var number: Int
@UserInfoKey("custom key") var text: String
var bar: Bar
}
@UserInfoRepresentable
struct Bar {
let value: String
}
And then, you can parse userInfo
like this.
let userInfo: [AnyHashable: Any] = [
"number": 123,
"custom key": "text",
"bar": [
"value": "bar"
],
]
let foo = try Foo(userInfo: userInfo)
And, you can also convert the type to userInfo
.
let userInfo: [AnyHashable: Any] = foo.convertToUserInfo()
