如何在Swift中使用SQLite中的一行填充字典？

Question

{'col1'：value1，'col2'：value2，'col3'：value3等}

在下面的代码中，如何存储整行值并将其存储在字典中？

    let queryStatementString = "SELECT * FROM TABLE WHERE val = ?;" 
    var queryStatement: OpaquePointer? = nil

    if sqlite3_prepare_v2(db, queryStatementString, -1, &queryStatement, nil) == SQLITE_OK {
        sqlite3_bind_text(queryStatement, 1, variable, -1, nil)

        while (sqlite3_step(queryStatement) == SQLITE_ROW) {
            let id = sqlite3_column_int(queryStatement, 0)
            let queryResultCol1 = sqlite3_column_text(queryStatement, 1)
            let queryResultCol2 = sqlite3_column_text(queryStatement, 0)

            let name = String(cString: queryResultCol1!            }
    }
    else {
        print("SELECT statement could not be prepared")
    }

    sqlite3_finalize(queryStatement)
