Feature: Decode logical Bool into a real Bool #50

Open
@Andy0570

Description

I've added a Bool type auto-conversion function, so if people want to add it to their projects, I'll try pulling requests.

JSON Swift
"false", "no", "0", "n", "f", 0, false false
"true", "yes", "1", "y", "t", 1, true true
import Foundation
@propertyWrapper
public struct BoolValue: Codable {
 public var wrappedValue: Bool
 public init(from decoder: Decoder) throws {
 let container = try decoder.singleValueContainer()
 if let stringifiedValue = try? container.decode(String.self) {
 switch stringifiedValue.lowercased() {
 case "false", "no", "0", "n", "f": wrappedValue = false
 case "true", "yes", "1", "y", "t": wrappedValue = true
 default:
 let description = "Expected to decode Bool but found a '\(stringifiedValue)' instead."
 throw DecodingError.dataCorruptedError(in: container, debugDescription: description)
 }
 } else if let integerifiedValue = try? container.decode(Int.self) {
 switch integerifiedValue {
 case 0: wrappedValue = false
 case 1: wrappedValue = true
 default:
 let description = "Expected to decode Bool but found a '\(integerifiedValue)' instead."
 throw DecodingError.dataCorruptedError(in: container, debugDescription: description)
 }
 } else {
 wrappedValue = try container.decode(Bool.self)
 }
 }
 public func encode(to encoder: Encoder) throws {
 try wrappedValue.encode(to: encoder)
 }
}

Usage:

@BoolValue var isFollow: Bool
