Property Wrapper

Overview

IntValue is a simple @propertyWrapper for object.

• It can be implemented in object.
• Look examples in code.

Simple Example

Code Implementation

First: Need to create struct uses @IntValue

struct Object: Decodable {
    @IntValue var id: Int
    @IntValue var value1: Int
    @IntValue var value2: Int
}

JSON For Decode data

let json = """
    {
        "id": null,
        "value1": 0,
        "value2": 343
    }
    """

let data = json.data(using: .utf8)!
let object = try! JSONDecoder().decode(Object.self, from: data)

print("Id is", object.id)
print("Value1 is", object.value1)
print("Value2 is", object.value2)

Result in console:

Id is 0
Value1 is 0
Value2 is 343
