Swift 4.2 To remove database:

func remove(realmURL: URL) {
        let realmURLs = [
            realmURL,
            realmURL.appendingPathExtension("lock"),
            realmURL.appendingPathExtension("note"),
            realmURL.appendingPathExtension("management"),
            ]
        for URL in realmURLs {
            try? FileManager.default.removeItem(at: URL)
        }
let url = Realm.Configuration.defaultConfiguration.fileURL!
remove(realmURL: url)

To clear database:

try? realm.write {
    realm.deleteAll()
}
