The problem is you are depending on the phone's time and date. For your purpose, you might have to connect to some server to get date time. There is another problem which you might come across, that is if the user doesn't open the app then, your app might not run any code hence won't show any notification.

1.So the solution will be setting up a push notification server. So here is what you can do :

Setup a push notification to the server and iDevice(Tutorial).
Make a logic for in the server such that first time the app registers and sends the device token id, save the date time also.
And run a Cronjob(what is it?) application in a server which will take the date and time and send messages based on the device token.

2.And in case you want to do it in the phone itself without depending upon server then. Here are the things you have to concern :

Make a logic, to save the date and time in database or user preferences.
Add any of the background services to awake the app from the suspended mode once every day.
Calculate the date and show push notification.

Ok then you might have to use database to save the date time first time it runs and check every day if from saved date 6 days have passed or not. Use CLVisit and locaiton service to awake the app every day once. — MD Aslam Ansari, Aug 18 '16 at 07:51
