Answer 1

How you have initialized groupPath? It should be the path of document directory, not the path of resource directory.

You should do something similar :

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *filePath = [documentsDirectory stringByAppendingPathComponent:FILE_NAME];

You can not edit the file that is present in the workspace.
