6. SQLite

  • SQLite Library (Recommended): A Swift wrapper around the SQLite C API. Use CocoaPods or Swift Package Manager to install it. This library simplifies database interactions significantly.
  • Database Connection: Open a connection to the SQLite database file.
  • SQL Queries: Execute SQL queries using the library's methods.
  • Data Retrieval: Retrieve data from the results of your queries.
Core Data (Alternative): A framework provided by Apple for managing persistent data. It can use SQLite as its underlying storage mechanism, but it provides a higher-level object-oriented interface.
