You have to organize your data by section first. I don't see that happening since you simply add all received items into one array.

Based on the screenshot you have provided and the project, it looks as if you are trying to display todo items by date where each section is for a different date. And as far as I can tell, your date value is in the dateLabel property.

If all of the above is correct, then you would need to convert the dateLabel property, which is a String, to an actual Date value so that you can work with the individual dates. Or, depending on how the date string is set up, you might be able to do the same thing by getting just the date component of the string. For example, if your date strings are like "2017-03-31 10:55am" or something, just getting the "2017-03-31" part should allow you to organize the todo items so that all items for the same date can be easily identified.

Once you do that, you have to set up some sort of a structure - if you go with date strings, then a dictionary might work - where you can identify all todo items for a given date. For example, if you have just the date extracted as a string (like "2017-03-31") then you could set up something like this:
