核心数据迁移＆＃34;无法取消链接支持目录＆＃34;

Question

使用自动迁移时，我有以下日志条目：

Failed to unlink support directory 
/..Test.sqlite_SUPPORT from old store location: /.Test.sqlite.migrationdestination due to 
Error Domain=NSCocoaErrorDomain Code=4 "The operation couldn’t be completed. (Cocoa error 4.)" UserInfo=0x15e7f830 {NSUnderlyingError=0x15e7a850 "The operation couldn’t be completed. No such file or directory", NSFilePath=/..Test.sqlite_SUPPORT, NSUserStringVariant=(
                    Remove
        )

然而，迁移不会失败。有谁知道这意味着什么？
