什么原因导致iOS iCloud错误：错误域= BRCloudDocsErrorDomain代码= 12“ *** 作无法完成.”延迟后重试：60

概述iPhone / iOS应用程序正在使用CoreData SQLite(NSSQLiteStoreType)iCloud iOS.当应用程序第一次安装(或通过 xcode删除和重新安装后)开始,并且iCloud中的先前的应用程序数据从先前安装或同一帐户中的其他设备发生,则会出现以下错误,然后是60秒的重试延迟,然后成功迁移到iCloud.结果是应用程序升级时,应用程序的用户认为他们的数据丢失.然而 iPhone / iOS应用程序正在使用CoreData sqlite(NSsqliteStoreType)iCloud iOS.当应用程序第一次安装(或通过 xcode删除和重新安装后)开始,并且iCloud中的先前的应用程序数据从先前安装或同一帐户中的其他设备发生,则会出现以下错误,然后是60秒的重试延迟,然后成功迁移到iCloud.结果是应用程序升级时,应用程序的用户认为他们的数据丢失.然而,在60秒的延迟之后,数据被恢复.错误和一些代码如下.

什么原因导致这个错误在哪里可以进一步了解这个错误？

解决方法 我希望我的答案可以为那些遇到这个错误的人节省很多时间.

当应用程序的删除和安装之间的时间小于一定间隔时,会发生此错误.我不知道是否和我一样,我的是15秒.

愚蠢的错误,浪费了几个小时.
