So I am making an application that i want to populate a huge array, I want the information in my array to be objects, with information from my file. So if there is a way to read/write to a file, does not have to be a excel file, how would I go about doing this, or is NSCoding the only way?
You can read/write files. Check out NSFileManager. There is no reason why you can’t read from an excel file, but for the sake of efficiency and simplicity it would be much better if you read from a CSV or JSON file.
