swift - 保存数据数组会导致快速崩溃

Question

我尝试将项目添加到 arrar 并保存在 Userdefault 中，但应用程序崩溃了，我希望有人指出我做错了什么

private func putArray(_ value: GMSAutocompletePrediction?, forKey key: String) {
        guard let value = value else {
            return
        }
        log("THE MESSAGE \(value)", .fuck)
        var newArray = getArray(forKey: key)
        log("THE MESSAGE ARRAY \(newArray)", .fuck)
        if newArray.contains(value) {
            newArray.remove(at: newArray.firstIndex(of: value)!)
        } else {
            newArray.append(value)
        }

        storage.setValue(NSKeyedArchiver.archivedData(withRootObject: newArray), forKey: key)
    }

崩溃错误

Answer 1

GMSAutocompletePrediction 不符合 NSCoding，因此您无法将其保存到用户默认值，您可以从中提取重要的详细信息并创建自定义模型来保存
