i pre-populating core data existing .sqlite following code: 

// put down default db if doesn't exist     nserror *error = nil;     nsfilemanager *filemanager = [nsfilemanager defaultmanager];     if (![filemanager fileexistsatpath:[storeurl path]]) {         nsstring *defaultstorepath = [[nsbundle mainbundle] pathforresource:@"xyz" oftype:@"sqlite"];         if (defaultstorepath) {             [filemanager copyitematpath:defaultstorepath topath:[storeurl path] error:&error];         }     }

it working until upgraded xcode , copies .sqlite file desired location not of same size. pre populated .sqlite file of 4.7 mb , when it's copied there above code it's of size 3.2 mb. , gives following error:

sqlite error code:1, 'no such table: z_metadata'
