Question

I have been searching for days to convert a fairly simple JSON string to an object type in Swift but with no avail.

Here is the code for web service call:

SWIFT4 - Easy and elegant way of decoding JSON strings to Struct.

First step - encode String to Data with .utf8 encoding.

Than decode your Data to YourDataStruct.

struct YourDataStruct: Codable {

let type, id: String

init(_ json: String, using encoding: String.Encoding = .utf8) throws {
    guard let data = json.data(using: encoding) else {
        throw NSError(domain: "JSONDecoding", code: 0, userInfo: nil)
    }
    try self.init(data: data)
}

init(data: Data) throws {
    self = try JSONDecoder().decode(YourDataStruct.self, from: data)
}                                                                      
}

do { let successResponse = try WSDeleteDialogsResponse(response) }
} catch {}
