Finish to create features for a native iPhone app in swift

The project is being half done, I need to add some features to the current code. The application if a finance tracker, at the moment it has wallets and categories and allows the user to add transactions. It users core data to store the user data as local database. The feature you need to currently add would be the following: Budget feature This is also an extra feature for the expenses tracker, the user can set up budgets on different categories. For example: A user usually spends a lot of money in restaurants and eating out, they decided that they want to control this. They choose the category and set up an allowance of how much money would be expend in that category during the month. The system would keep track and deducted the expenses of that category. The user would be able to see all the time how much money he has spent on this category, but also how much he has left from the budget allocated. And received notification when the budget limit is about to be reached, and when the budget is being exceeded and for how long is being exceeded. Debs/Loans Mode The users would be able to use this feature to track the money they borrowed form someone or to someone. This would allow them to add the person who borrow to/from, the amount, date must be returned or received back. Would be useful for the them, in case they have something important to pay, the application would remind them previously when it must be pay back that debt. The system would also notify of the loans they have made to other people, and when they should expect that money back. In both cases the system would confirm with the user if the debt has been paid or the loan has been returned, the user must confirm it so they system would complete this transaction or add an extended date. The application would create automatic transactions added to the main system, as well as allow the user to input small payments received or done towards this deb or loan. I need this features to be completed in a week. thanks
