在我们的应用程序中，我们使用URLSession.shared.data(for:,delegate:)和JSONDecoder进行rest API调用。在iOS>=16.1上，它可以工作。但在iOS=>17.0上使用TestFlight，它崩溃了。很难调查这个bug，因为我在MacOS 12.6上的Xcode 14.2上卡住了。我可以在服务器上确认API调用返回的statusCode为200。所以我假设问题可能是JSONDecoder因为我甚至不能捕获错误并在UI中显示它。这里有一些上下文的API代码：
func sendRequest<T: Decodable>(endpoint: Endpoint, responseModel: T.Type, allowRetry: Bool = true, authManager: AuthManager? = nil, keyDecodingStrategy: JSONDecoder.KeyDecodingStrategy = .useDefaultKeys) async -> Result<T, RequestError> {
var urlComponents = URLComponents()
urlComponents.scheme = endpoint.scheme
urlComponents.host = endpoint.host
urlComponents.path = endpoint.path
urlComponents.queryItems = endpoint.queryItems
guard let url = urlComponents.url else { return .failure(.invalidURL(nil))}
var request = URLRequest(url: url, timeoutInterval: 5.0)
request.allHTTPHeaderFields = endpoint.header
request.httpMethod = endpoint.method.rawValue
if let body = endpoint.body {
do {
request.httpBody = try JSONSerialization.data(withJSONObject: body, options: [])
} catch {
return .failure(.unexpected(error.localizedDescription))
}
}
do {
let (data, response) = try await URLSession.shared.data(for: request, delegate: nil)
guard let response = response as? HTTPURLResponse else { return .failure(.noResponse(nil))}
switch response.statusCode {
case 204:
return .success("" as! T)
case 200...299:
print("done")
let decoder = JSONDecoder()
decoder.keyDecodingStrategy = keyDecodingStrategy
let result = try decoder.decode(responseModel, from: data)
return .success(result)
case 400:
let decoder = JSONDecoder()
let error = try decoder.decode(CheckoutError.self, from: data)
return .failure(.badRequest(error.error))
}
} catch {
guard let urlError = error as? URLError else {return .failure(.unexpected(nil))}
switch urlError.code {
case .notConnectedToInternet,
.dataNotAllowed:
return .failure(.addressUnreachable(urlComponents.url!))
case .timedOut:
return .failure(.unexpected("Request timed out. Try again"))
default:
return .failure(.unexpected(nil))
}
.failure(.addressUnreachable(urlComponents.url!))
}
}字符串
呼叫站点：
let queryValue = "*,categories_details(*),accessories_details(*),colors_details(*),sizes_details(*),subcategories_details(*),price_ranges_details(*)"
let queryItems = ["select": queryValue]
let result = await sendRequest(endpoint: PCDBEndpoint.lookupTable(apikey: authManager.apikey, accessToken: authManager.apikey, queryItems: queryItems), responseModel: [LookupTable].self, keyDecodingStrategy: .convertFromSnakeCase)型
有人经历过吗？你怎么修好的有没有其他方法可以在没有Xcode 15的情况下进行调试？为了避免破坏iOS 17中引入的更改，是否可以更改Xcode中的设置，使代码在iOS 17上回退到iOS 16.1。
为了解决这个问题，我尝试了以下方法：1-Symbolate Crash Log 2- Run UI Tests to lunch the app using Xcode Cloud
1-符号化崩溃日志：我已经附上了符号化的崩溃日志。看起来，问题似乎与主函数有关。我还将API调用替换为静态值。

2-使用Xcode Cloud运行UI测试：
在Xcode云上，操作系统配置设置为iOS 17。我得到了这个测试失败，这似乎证实了我在运行iOS 17的真实的设备上遇到的运行时错误。
任何帮助，以解决这个问题将有很长的路要走。谢谢。

按热度按时间8aqjt8rx1#
您可能希望从可能崩溃的代码部分开始：
字符串
如果
body包含非plist值，则会崩溃。（Plist-values是数组、字典、字符串、数字、布尔值和NSNull，不能包含NaN或无穷大。除非传递.fragmentsAllowed，否则顶级对象必须是数组或字典。）这是应该避免JSONSerialization而首选JSONEncoder的一个原因。您的代码似乎假定它会抛出错误，但它实际上抛出了一个Swift无法捕获的异常。这是我首先要查看的地方。我会查看PCDBEndpoint，并确保在所有情况下，它返回的每个属性都是一个plist值。如果你在这个主体中包含Apple类型，这肯定是我要查找错误的地方，因为内部类型可能已经更改，或者值可能是NaN或无穷大。
有关详细信息，请参见
data(withJSONObject:options:)：如果
obj无法生成有效的JSON，JSONSerialization会抛出异常。此异常发生在解析之前，表示编程错误，而不是内部错误。在调用此方法之前，您应该检查输入是否可以使用isValidJSONObject(_:)生成有效的JSON。参见
JSONSerialization：要将Foundation对象转换为JSON，对象必须具有以下属性：
调用
isValidJSONObject(_:)或尝试转换是判断JSONSerialization类是否可以将给定对象转换为JSON数据的明确方法。型
这将在T不是String的任何情况下崩溃（在这种情况下它不是）。这不太可能是原因，但在服务器意外返回204时崩溃您的应用程序并不是一个好主意。
型
这永远不会崩溃，因为前面已经检查过使用
if-let，但我建议在这里使用您的本地url而不是!。您已经完成了if-let工作;您可能会从中受益。
