Recent Files Database

[iswiftshek]

I made recent files database using CoreData. When a file is opened, we check if it already exists in the database. If it does, that entry is deleted and a new one is saved.

The following attributes are stored:

• day, month, year
• fileName, fileURL, fileSize
• mimeType, mtime
• serverName
• authToken

A getRecentFiles() function returns an array of recentFiles, where each element is a struct containing the attributes stored. A fileDisplayText is also returned which is a calculated string that could be one of these: "Today", "Yesterday", "This Week", "This Month", "July 2019" (example), "2018" (example).
Based on these strings, we will group the cells and divide them into sections. We could also divide them based on serverName. @Marton-Zeisler will make the RecentFilesViewController and give it a nice UI.

For now, I have added a button on the top left of the servers screen that presents a VC containing the recent files record. This is just a temporary screen to only view the files and test the working of the database. The database stores 50 recent files and deletes the older records as the new ones are added.

This is how it looks:-
