SwiftUI SQLite Database Storage Tutorial Collection (2022 Edition)

I. What is SQLite

SQLite is a C library that implements a small, fast, self-contained, highly reliable, full-featured SQL database engine.SQLite is an in-process library that implements a self-contained, serverless, zero-configuration, transactional SQL database engine.

SQLite is an embedded SQL database engine.Unlike most other SQL databases, SQLite does not have a separate server process.SQLite reads and writes ordinary disk files directly.A complete SQL database with multiple tables, indexes, triggers, and views contained in a single disk file.The database file format is cross-platform - we can freely copy the database between 32-bit and 64-bit systems.These features make SQLite a popular choice for application file formats.It is the most used database engine in the world.SQLite is built into all phones and most computers, and bundled with countless other applications that people use every day.
