Sample text

You can loop the values by checking the return code, which should be 0 or OK. For this app, I am creating an instance of the Db class for each iteration and assigning its name property the value of the returned name column in the query. Converting the C string to a Swift string requires some fancy footwork. To retrieve a column value, you need to use one of the preparedStatements column methods of the corresponding type. Since the name column in the database I will create later has a varchar data type, I need to use the sqlite3_column_text method.

The titleForHeaderInSection returns the Section Title, so, for this app, this would be Databases, Tables, Views, Indexes, and Triggers. The numberOfSectionsinTableView function will how many sections the TableView will contain. For this app, it will be 5, which is the number of elements in the schemaSections array. numberOfRowsInSection configures the number of rows to display. This is usually the count of elements in the array that is serving as the data source. count. The last required function, cellForRowAtIndexPath, defines the cell display.

The map is used to extrapolate only the last part of the returned paths. The filter and map design have been reworked in the latest version of Swift to apply a mapReduce pattern of sorts. The design pattern eliminates the need to iterate through an array, hence it is much more efficient. The filter uses a Boolean expression to test and return the reduced list. The map function is used to extract or perform a transformation on portions of a collection that has been filtered. The executeQuery function The executeQuery, as its name implies, executes SQLite queries.
