I have an application based on the documents and I would like that when you create a new file the tableview are pre-populated with default data. I did the following:

  1. I launched my application and I populated the tables, then I saved the file Untitled.sqlite
  2. I imported the file Untitled.sqlite between the resources of my application
  3. I inserted the following code in the following file


- (id)init {
self = [super init];
if (self) {
    // Add your subclass-specific initialization here.
    NSFileManager *fileManager = [NSFileManager defaultManager];
    if (![fileManager fileExistsAtPath:@"/Users/andreabollini/Library/Developer/Xcode/DerivedData/Preventivi-euqsrtroavapbwfjvljrxamywbvf/Build/Products/Debug/"]) {
        NSString *defaultStorePath = [[NSBundle mainBundle]
                                      pathForResource:@"Untitled" ofType:@"sqlite"];

        if (defaultStorePath) {
            [fileManager copyItemAtPath:defaultStorePath toPath:@"/Users/andreabollini/Library/Developer/Xcode/DerivedData/Preventivi-euqsrtroavapbwfjvljrxamywbvf/Build/Products/Debug/" error:NULL];
            [tabella1 reloadData];
            [tabella2 reloadData];
return self;}

There are no errors, but it does not work. When I open the application, the tableview remains empty and nothing happens. What's wrong?
