Swift read from JSON dictionary - json

Question

I am sending an Alamofire request and inside of my completion handler I have:
if let jsonData = response.result.value {
result = jsonData
guard let data = result.data(using: .utf8) else { return}
guard let dictionary = try? JSONSerialization.jsonObject(with: data, options: []) as? [String: Any] else {
print("Could not cast JSON content as a Dictionary<String, Any>")
return
}
print("dictionary: \(dictionary)")
if dictionary["status"] as! String == "false"{
//Do something
}
}
else{
result = "\(response.error)"
}
The result of printing dictionary is ["status":false, "value":A1]. Ultimately I want to use status for my if statement. However I get a crash on the if statement line: if dictionary["status"] as! String == "false" of Fatal error: Unexpectedly found nil while unwrapping an Optional value. I also tried changing the line to if dictionary["status"] as! Bool == false and I get the exact same error.
The json as returned from the request is:
{
"value": "A1",
"status": "false"
}
So my question is, what is the correct way to get the value for status out of dictionary?
Would something like this work?
struct jsonOut: Codable {
let value: String
let status: String
}
if let jsonData = response.result.value {
result = jsonData
guard let data = result.data(using: .utf8)
let status = try JSONDecoder().decode(jsonOut.self, from: data)
}

Since the JSON has the format:
{
"value": "A1",
"status": "false"
}
The correct way is using Codable with the same format as the JSON:
struct jsonOut: Codable {
let value: String
let status: String
}
if let jsonData = response.result.value {
result = jsonData
guard let data = result.data(using: .utf8)
let statusData = try JSONDecoder().decode(jsonOut.self, from: data)
print("status: \(statusData.status)"
}
