I need to parse below sample strings to get status and code and bind it to a struct "ErrorData".

String1 - ("{\n \"errors\" : [ {\n \"status\" : \"400\",\n \"code\" : \"INVALID_DATA\"\n } ]\n}")

String2 - "{\n \"errors\" : [ {\n \"status\" : \"404\",\n \"code\" : \"INVALID_AUTH\"\n } ]\n}")

public struct ErrorData  {
    var errorStatus: String?
    var errorCode: String?
}

These are only 2 samples string, there will be many more strings of same format with different status and code value. How do I parse above string with format as shown above.

This is JSON. These structs match the data

struct ErrorData : Decodable {
    let errors : [ErrorItem]
}

struct ErrorItem : Decodable {
    let status, code : String
}

Parse it with

let jsonString = """
{"errors":[{"status":"400","code":"INVALID_DATA"}]}
"""

do {
    let result = try JSONDecoder().decode(ErrorData.self, from: Data(jsonString.utf8))
    for item in result.errors {
        print(item.status, item.code)
    }
} catch {
    print(error)
}
