struct Meta: Codable {
let isEnd: Bool
enum CodingKeys: String, CodingKey {
case isEnd = "is_end"
}
}
let jsonStr = """
{
"is_end" : true
}
"""
let jsonData = jsonStr.data(using: .utf8)!
do {
let decoder = JSONDecoder()
decoder.keyDecodingStrategy = .convertFromSnakeCase
let result = try decoder.decode(Meta.self, from: jsonData)
print(result)
} catch {
print(error)
}
Code written in the above manner will result in the corresponding error.
keyNotFound(CodingKeys(stringValue: "is_end", intValue: nil), Swift.DecodingError.Context(codingPath: [], debugDescription: "No value associated with key CodingKeys(stringValue: \"is_end\", intValue: nil) (\"is_end\").", underlyingError: nil))
I think there is nothing wrong with the code. But why is the error occurring?
And, Can't the enum be named something other than CodingKeys?
like this,
struct Meta: Codable {
let isEnd: Bool
enum CodingKeyss: String, CodingKey {
case isEnd = "is_end"
}
}
And these codes return normal results. What's the reason
Meta(isEnd: true)
