Objective-C Reading File

Question

I am learning how to write simple Objective-C programs (without a GUI). I created a new xcode project and have the following files in the top level directory:

main.m
data.txt

How can I get the contents of data.txt as an NSString for use in main.m?

I tried:

+ (NSString *)loadTextFileToString:(NSString*)fileDest {
    NSString *filePath = [[NSBundle mainBundle] pathForResource:fileDest
                                                     ofType:@"txt"];
    NSError *error = nil;
    NSString *fileContent = [NSString stringWithContentsOfFile:filePath
                                                  encoding:NSUTF8StringEncoding
                                                     error:&error];
    if(error) {
        NSLog(@"ERROR while loading from file: %@", error);
    }
    return fileContent;
}

And passing @ "data" as an argument, but it gives me an error:

ERROR while loading from file: Error Domain=NSCocoaErrorDomain Code=258 "The file name is invalid."

What is the right way to do this?
