Question

我使用FMDB和Swift 3。在Swift 2上一切正常，但在进行Swift升级之后，我得到了：＆＃34;命令因信号失败：被杀：9＆＃34;

在调查其原因后，我发现正在执行＆＃34; executeUpdate＆＃34;在ArgumentsArray中有大约24个参数会导致编译器非常慢并最终返回编译错误。

当将数组中的参数数量减少到20时，编译器构建仍然很慢但成功完成。

任何想法为什么/帮助都会受到欢迎......！

这是我的代码：（构建成功但是取消注释下面的4行会使编译构建失败。当然，任何其他4行都会有相同的结果）

func insertLocalization(_ localization: Localization) -> Bool {
        print ("Insert Localization: \(localization.localization_object_id!)#\(localization.spot_object_id!)#\(localization.language_code!)")
        sharedInstance.database!.open()
        let isInserted = sharedInstance.database!.executeUpdate(
            "INSERT INTO localizations (" +
                "localization_object_id, " +
                "spot_object_id, " +

            withArgumentsIn: [

                localization.direction_nw_title!,
                localization.direction_nw_desc!
            ])
        sharedInstance.database!.close()
        return isInserted
    }

谢谢！

此代码在Xcode 8.0（8A218a）中编译时没有任何意外。但如果这对你不起作用，我建议拆分该行，例如

let values =  [localization.localization_object_id!, ..., localization.direction_nw_desc!]

let isInserted = sharedInstance.database!.executeUpdate(
    "INSERT INTO localizations (...) " +
    "VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?)",
    withArgumentsIn: values)

FMDB，Swift 3，executeUpdate - 编译器构建失败
