SQLite packaged for the Swift Package Manager.
The package contains the SQLite amalgamation built using the recommended compile-time options.
The default build configuration includes the FTS5 extension, built-in SQL math functions, the R*Tree index extension, database snapshots, sqlite_stmt table, and the sqlite_stat4 table.
Additionally, the carray, decimal, ieee754, percentile, series, sha3, and uuid extensions are statically linked.
The package also includes shims for various C functions not easily accessible from Swift.
For Swift 6.1 and later the build configuration and features may be customized using package traits.
The following traits are used to specify the build configuration and the defaults reflect the SQLite recommended compile-time options:
| Package Trait | Default | SQLite Compile-Time Option |
|---|---|---|
| DQS_0 | Y | SQLITE_DQS=0 |
| DQS_1 | SQLITE_DQS=1 | |
| DQS_2 | SQLITE_DQS=2 | |
| DQS_3 | SQLITE_DQS=3 | |
| THREADSAFE_0 | Y | SQLITE_THREADSAFE=0 |
| THREADSAFE_1 | SQLITE_THREADSAFE=1 | |
| THREADSAFE_2 | SQLITE_THREADSAFE=2 | |
| DEFAULT_MEMSTATUS_0 | Y | SQLITE_DEFAULT_MEMSTATUS=0 |
| DEFAULT_WAL_SYNCHRONOUS_1 | Y | SQLITE_DEFAULT_WAL_SYNCHRONOUS=1 |
| LIKE_DOESNT_MATCH_BLOBS | Y | SQLITE_LIKE_DOESNT_MATCH_BLOBS |
| MAX_EXPR_DEPTH_0 | Y | SQLITE_MAX_EXPR_DEPTH=0 |
| OMIT_DECLTYPE | Y | SQLITE_OMIT_DECLTYPE |
| OMIT_DEPRECATED | Y | SQLITE_OMIT_DEPRECATED |
| OMIT_PROGRESS_CALLBACK | Y | SQLITE_OMIT_PROGRESS_CALLBACK |
| OMIT_SHARED_CACHE | Y | SQLITE_OMIT_SHARED_CACHE |
| USE_ALLOCA | Y | SQLITE_USE_ALLOCA |
| OMIT_AUTOINIT | Y | SQLITE_OMIT_AUTOINIT |
| STRICT_SUBTYPE_1 | Y | SQLITE_STRICT_SUBTYPE=1 |
Important
The DQS_ traits are mutually exclusive and only one should be specified.
The SQLite default is SQLITE_DQS=3 but the SQLite recommended value is SQLITE_DQS=0.
Important
The THREADSAFE_ traits are mutually exclusive and only one should be specified.
The SQLite default is SQLITE_THREADSAFE=1 but the SQLite recommended value is SQLITE_THREADSAFE=0.
The following traits enable commonly-used SQLite features:
| Package Trait | Default | SQLite Feature |
|---|---|---|
| ENABLE_BYTECODE_VTAB | SQLITE_ENABLE_BYTECODE_VTAB | |
| ENABLE_COLUMN_METADATA | SQLITE_ENABLE_COLUMN_METADATA | |
| ENABLE_DBPAGE_VTAB | SQLITE_ENABLE_DBPAGE_VTAB | |
| ENABLE_DBSTAT_VTAB | SQLITE_ENABLE_DBSTAT_VTAB | |
| ENABLE_FTS4 | SQLITE_ENABLE_FTS4 | |
| ENABLE_FTS5 | Y | SQLITE_ENABLE_FTS5 |
| ENABLE_GEOPOLY | SQLITE_ENABLE_GEOPOLY | |
| ENABLE_MATH_FUNCTIONS | Y | SQLITE_ENABLE_MATH_FUNCTIONS |
| ENABLE_NORMALIZE | SQLITE_ENABLE_NORMALIZE | |
| ENABLE_PREUPDATE_HOOK | SQLITE_ENABLE_PREUPDATE_HOOK | |
| ENABLE_RTREE | Y | SQLITE_ENABLE_RTREE |
| ENABLE_SESSION | SQLITE_ENABLE_SESSION | |
| ENABLE_SNAPSHOT | Y | SQLITE_ENABLE_SNAPSHOT |
| ENABLE_STMTVTAB | Y | SQLITE_ENABLE_STMTVTAB |
| ENABLE_STAT4 | Y | SQLITE_ENABLE_STAT4 |
Note
The ENABLE_SESSION trait also sets the ENABLE_PREUPDATE_HOOK trait.
SQLite is in the public domain.
