Harmony provides CloudKit sync for GRDB and only GRDB.
Note: As this is in active development, documentation and tests are lacking, if not missing altogether, at this stage.
After installing via Swift Package Manager and enabling CloudKit for your app, add the following to your App.swift or equivalent to initialize Harmony.
@Harmony(
records: [Model1.self, Model2.self],
configuration: Harmony.Configuration(
cloudKitContainerIdentifier: "xxx" \\ Or leave nil for your default container.
),
migrator: // Your GRDB DatabaseMigrator
) var harmony
You can then access your Harmony instance from anywhere for writing or reading by simply using:
@Harmony var harmony
Harmony provides access to write methods that will automatically sync to CloudKit and hides direct database writing access for this purpose. If you write via another means to your GRDB database, Harmony will not see those changes.
Harmony also provides direct access to your DatabaseReader if you wish to read directly. I highly suggest seeing if GRDBQuery will fit your needs first.
