当在Simulator中调用此基于目标C的方法时，没关系。但是在真正的iPhone设备中，Thread 1: signal SIGABRT

warning: could not execute support code to read Objective-C class data in the process. This may reduce the quality of type information available.

这是代码

+ (NSData *)aesDecrypt:(NSURL *)url :(NSString *)key {

NSData *data = [NSData dataWithContentsOfURL: url];
if (data == nil) {
    NSLog(@"file not found");
    return nil;
}

char keyPtr[kCCKeySizeAES128];
bzero(keyPtr, sizeof(keyPtr));

[key getCString:keyPtr maxLength:sizeof(keyPtr)];

size_t bufferSize = [data length] + kCCBlockSizeAES128;
size_t decryptedBytesSize = 0;

void *buffer = malloc(bufferSize);

CCCryptorStatus result = CCCrypt(kCCDecrypt, kCCAlgorithmAES128, …

我想使用 decodeable 解析 JSON，但我得到一个错误类型不匹配，例如：

Swift.DecodingError.Context(codingPath: [], debugDescription: "预期解码数组，但找到了字典。"

我的 JSON ：
