Complete 3 views in the SwiftUI App

Hello. I would like to help with my current project. Attachments are 4 Views.

1- CalendarView, I want the calendar to expand when I drag it down or up and it is on the current day or the day that was pressed, and when I press the button it takes me back to the current day like video 1.

2- FullCalendarView, I want the calendar to be displayed on a week or month, or a full screen display of the month. When clicking on the specific date, it zooms out to a month (not full scrren), and the bottom list expands according to the calendar, such as Video 2.

3- LocationView, When entering the view, it takes about 8 seconds for the current site to be displayed. I want the site to be displayed directly.

4- BookView, I want the total pages and the current page to be displayed, and when clicking or dragging for the thumbnails at the bottom, the transfer will take place to the specified page and the pages will be flipped like picture 3.

Thanks..
