Keep getting the error “Expected to decode Array<Any> but found a dictionary | Swift - ios

Question

I have the following JSON that is formatted like this:
{
"error":false
}
I understand that is not an array because it does not include square brackets on both sides, but I cannot seem to understand how to properly get Swift to interpret this correctly.
This is the structure I am using:
struct CheckStruct: Decodable {
let error: String?
}
And the following is the function that should read the JSON:
private func JSONFunc() {
guard let url = URL(string: "https://example.com/example/example.php"),
let value = name.addingPercentEncoding(withAllowedCharacters: .urlQueryValueAllowed)
else { return }
var request = URLRequest(url: url)
request.httpMethod = "POST"
request.httpBody = "number=\(number)".data(using: .utf8)
URLSession.shared.dataTask(with: request) { data, _, error in
guard let data = data else { return }
do {
self.CheckRecord = try JSONDecoder().decode(Array<CheckStruct>.self,from:data)
DispatchQueue.main.async {
// Do something
}
}
catch {
print(error)
}
}.resume()
}
UPDATE:
If I were to use the results of the function to create an if else statement, how would this look?
For example if results are true do this..
else do this...

Answer 1

Your model should be like this:
struct CheckStruct: Codable {
let error: Bool?
}
And your function should be like this:
private func JSONFunc() {
guard let url = URL(string: "https://example.com/example/example.php"),
let value = name.addingPercentEncoding(withAllowedCharacters: .urlQueryValueAllowed)
else { return }
var request = URLRequest(url: url)
request.httpMethod = "POST"
request.httpBody = "number=\(number)".data(using: .utf8)
URLSession.shared.dataTask(with: request) { data, response, error in
guard let data = data else { return }
do {
let myData= try JSONDecoder().decode(CheckStruct.self, from:data)
print(myData.error)
} catch {
print(error)
}
}.resume()
}
BONUS
//Create Typealias
typealias BoolHandler = ((Bool?) -> Void)
//Create Function with Completion
private func fetchData(_ completion: #escaping BoolHandler) {
guard let url = URL(string: "https://example.com/example/example.php"),
let value = name.addingPercentEncoding(withAllowedCharacters: .urlQueryValueAllowed)
else { return }
var request = URLRequest(url: url)
request.httpMethod = "POST"
request.httpBody = "number=\(number)".data(using: .utf8)
URLSession.shared.dataTask(with: request) { data, response, error in
guard let data = data else { return }
do {
let myData= try JSONDecoder().decode(CheckStruct.self, from:data)
DispatchQueue.main.async {
completion(myData.error)
}
} catch {
DispatchQueue.main.async {
completion(nil)
}
}
}.resume()
}
//Call Method
fetchData { isSuccess in
if isSuccess {
// Do something
} else {
// Do something
}
}
I hope it will work for you.
Enjoy.
