Convert swift dictionary to JSON view. Helpful for copy-paste data from console to postman.

Dictionary+jsonView.swift

extension Dictionary {
    func jsonView() -> String {
        guard let data = try? JSONSerialization.data(withJSONObject: self, options: .prettyPrinted) else { return "" }
        return String(data: data, encoding: .utf8) ?? ""
    }
}

log.swift

// MARK: - Network Logging
private func log(request: URLRequest, response: HTTPURLResponse?, data: Data?, error: Error?) {
    print("=============================================")
    print("URL:", request.url?.absoluteString ?? "")
    print("Method:", request.httpMethod ?? "")
    print("Headers:", request.allHTTPHeaderFields ?? "")
    if let body = prettyString(request.httpBody) {
        print("HTTP Body:", body)
    }
    
    print("Status:", response?.allHeaderFields["Status"] ?? "")
    if let responseJSON = prettyString(data) {
        print("Response:", responseJSON)
    }
    error.map { print("Error:", $0) }
    print("=============================================")
}

private func prettyString(_ data: Data?) -> String? {
    if let data = data,
        let json = try? JSONSerialization.jsonObject(with: data, options: .allowFragments),
        let prettyData = try? JSONSerialization.data(withJSONObject: json, options: .prettyPrinted),
        let jsonString = String(data: prettyData, encoding: .utf8) {
        return jsonString
    } else {
        return nil
    }
