Example

There is a User type that conforms to the as following Codable protocol.

struct User: Codable {
    let name: String
    let age: Int
}

However, JSON which can not be mapped to User is sometimes delivered.

{
    "name": "Tom",
    "age": "18"
}

This is an error in Codable as follows.
"Expected to decode Int but found a string/data instead."

You can avoid such problems by using LooseCodable.

For example, User is rewritten as follows...

import LooseCodable

struct User: Codable {
    let name: String

    // Wrap the type of property that may receive unintended data in `LooseCodable`.
    private let _age: LooseCodable<Int>

    // public type is not changed.
    var age: Int {
        return self._age.value
    }

    enum CodingKeys: String, CodingKey {
        case name
        case _age = "age"
    }
}

You can also map to User with problematic JSON.
