Question

我有一些使用try and catch的代码，但是我看到了一些与该代码有关的崩溃报告。怎么可能呢？我该如何捕捉所有这些崩溃？

代码（使用SwiftyJSON）：

@objc class func produce(data: Data) -> [MyPair]? {
    guard let json = try? JSON(data: data) else {
        return nil
    }

    var pairs : [MyPair] = []
    do {
        let itemArray = try json["key1"]["key2"]["key3"].arrayValue()
        for item in itemArray {
            pairs.append(buildPair(with: item))
        }
    } catch {
        print(error)
    }

    return pairs
}

其中一次崩溃的堆栈跟踪：
