```swift
public extension KeyedDecodingContainer where Key: CodingKey {
    public func decodeBoolAsIntOrString(forKey key: K) throws -> Bool {
        if let bool = try? decode(Bool.self, forKey: key) {
            return bool
        }
        if let bool = try? decode(String.self, forKey: key) {
            return bool == "1"
        }
        let int = try decode(Int.self, forKey: key)
        return int == 1
    }

    public func decodeBoolAsIntOrStringIfPresent(forKey key: K) throws -> Bool? {
        if let bool = try? decodeIfPresent(Bool.self, forKey: key) {
            return bool
        }
        if let bool = try? decodeIfPresent(String.self, forKey: key) {
            return bool == "1"
        }
        if let int = try? decodeIfPresent(Int.self, forKey: key) {
            return int == 1
        }
        return nil
    }
}
```

Because, you know, sometimes the backend guys send us a 1 or TRUE and expect us to map it to native Bool object, well, they are kinda right, it shouldn't matter that much

Decode Bool from Int or String
