iOS Swift insert into sqlite FMDB

here is my issue : I have this wine app, that shows the content of my database to the user in a nice tableview. I can get data from it quite easily, using the FMDB executeQuery function, but whenever I try to add something to the SQLite table, it just fails.

Here is the code I use.

do { try sharedInstance.database!.executeUpdate("INSERT INTO wine VALUES (?, ?, ?)", values: [id, name, wineType]) } catch { print("error \(error)") }

I've tried putting everything in one string, and then send it as the first parameter, and putting nil as a second parameter, and that also fails. This syntax comes from the Data Sanitisation section in the FMDB README from github

I've found a few similar cases, but the answers were Objective-C. Please note that I am completely new to iOS, I don't know anything about Objective-C, and this is my first Swift app.

What am I doing wrong ?
