How to delete .sqlite3 file i.e. the database file in SWIFT?

Question

I'm using SQLite.swift library in my iOS app for database needs. I'm using more than one database with different names. I'm doing it fine no problems. At one point I need to delete the .sqlite3 file i.e., the whole database file when it's no longer needed. I'm a newbie to Swift3. So I don't know how to delete the database. My app has a database called AccountsDB to store the number of profiles. Each profile has a database with it's name. When user deletes one profile I need to delete the database with that name too. This is my scenario. Please guide me to achieve my task. Thanks.

Use FileManager to delete the physical file from your device. I assume you know (or can retrieve) the path to the SQLite DB file, right? In that case, if url is the file URL to your file:

let fm = FileManager.default
do {
    try fm.removeItem(at:url)
} catch {
    NSLog("Error deleting file: \(url)")
}
