How to using Like with Text in FMDB query iOS Swift 4?

I wanna get query with like and try like this:

let name = "pp" //apple

let db = openDB()
  do {
      var queryString = "select * from products where name like '%?%' and deleted = 0 order by id desc"
      let rs = try db.executeQuery(queryString, values:[name])
      var arr:Array<Product> = []
      while rs.next() {
      arr.append(parseProductDB(rs))
      }
      closeDB(db)
} catch {
      print("failed: \(error.localizedDescription)")
      closeDB(db)
}

but it does not work.

Just try this:

let db = openDB()
do {
    var queryString =
    queryString = String(format:"select * from products where name like '%%%@%%' and deleted = 0 order by id desc",name)
    let rs = try db.executeQuery(queryString, values:nil)
    var arr:Array<Product> = []
    while rs.next() {
    arr.append(parseProductDB(rs))
    }
    closeDB(db)

} catch {
            print("failed: \(error.localizedDescription)")
            closeDB(db)
}
