You're trying to write to the resource directory which you probably don't have permission to do. Try changing the first line of your code to point to the document directory:

NSArray *savePaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSMutableString *savePath = [NSMutableString stringWithString:[savePaths objectAtIndex:0]];
[savePath appendString:@"/myFile.txt"];

Also, you don't need to worry about file handles. NSData is capable of writing itself to disk:

BOOL result = [data writeToFile:savePath atomically:YES];
