  • v0.75.1 Changes

    🚀 Released July 8, 2016

    🛠 Fixed

    • 🛠 Fixed a crash that would happen when performing a full text search in a DatabasePool (fixes #80)

  • v0.75.0 Changes

    🚀 Released July 8, 2016

    💥 Breaking change

    • 📚 Row adapters have been refactored (documentation).

       // Row "variants" have been renamed row "scopes":
 struct Row {
-    func variant(named name: String) -> Row?
+    func scoped(on name: String) -> Row?
 }

 // Scope definition: VariantRowAdapter has been renamed ScopeAdapter:
-struct VariantRowAdapter : RowAdapter {
-    init(variants: [String: RowAdapter])
-}
+struct ScopeAdapter : RowAdapter {
+    init(_ scopes: [String: RowAdapter])
+}

 // Adding scopes to an existing adapter:
 extension RowAdapter {
-    func adapterWithVariants(variants: [String: RowAdapter]) -> RowAdapter
+    func addingScopes(scopes: [String: RowAdapter]) -> RowAdapter
 }

 // Implementing custom adapters
 protocol ConcreteRowAdapter {
-    var variants: [String: ConcreteRowAdapter] { get }
+    var scopes: [String: ConcreteRowAdapter] { get }
 }

  • v0.74.0 Changes

    🚀 Released July 6, 2016

    🆕 New

    • 📚 TableMapping protocol lets you delete rows identified by their primary keys, or any columns involved in a unique index (closes #56, documentation):

      try Person.deleteOne(db, key: 1)
try Person.deleteOne(db, key: ["email": "[email protected]"])
try Citizenship.deleteOne(db, key: ["personID": 1, "countryCode": "FR"])
try Country.deleteAll(db, keys: ["FR", "US"])

    💥 Breaking change

    • The fetch(_:keys:), fetchAll(_:keys:) and fetchOne(_:key:) methods used to accept any dictionary of column/value pairs to identify rows. Now these methods raise a fatal error if the columns are not guaranteed, at the database level, to uniquely identify rows: columns must be the primary key, or involved in a unique index:

      // CREATE TABLE persons (
//   id INTEGER PRIMARY KEY, -- can fetch and delete by id
//   email TEXT UNIQUE,      -- can fetch and delete by email
//   name TEXT               -- nope
// )
Person.fetchOne(db, key: ["id": 1])                       // Person?
Person.fetchOne(db, key: ["email": "[email protected]"]) // Person?
Person.fetchOne(db, key: ["name": "Arthur"]) // fatal error: table persons has no unique index on column name.

      This change harmonizes the behavior of those fetching methods with the new deleteOne(_:key:) and deleteAll(_:keys:).

  • v0.73.0 Changes

    🚀 Released June 20, 2016

    👌 Improved

    • FetchedRecordsController doesn't check for changes when a database transaction modifies columns that are not present in the request it tracks.

    🆕 New

    • 📚 The query interface lets you provide arguments to your sql snippets (documentation):

      let wines = Wine.filter(sql: "origin = ?", arguments: ["Burgundy"]).fetchAll(db)

    • 📚 Transaction observers can efficiently filter the database changes they are interested in (documentation).

    • 👌 Support for NSUUID (documentation)

  • v0.72.0 Changes

    🚀 Released June 9, 2016

    👌 Improved

    • NSDecimalNumber used to store as a double in the database, for all values. Now decimal numbers that contain integers fitting Int64 attempt to store integers in the database.

    💥 Breaking Changes

  • v0.71.0 Changes

    🚀 Released June 5, 2016

    🛠 Fixed

    • 🛠 Fix a crash that would sometimes happen when a FetchedRecordsController's callbacks avoid retain cycles by capturing unowned references.
    • 👌 Improved handling of numeric overflows. Fixes #68.

    🆕 New

    • 📚 GRDB can now use a custom SQLite build (documentation). Merged #62 by @swiftlyfalling.
    • 📚 With a custom SQLite build, transaction observers can observe individual column values in the rows modified by a transaction (documentation). Merged #63 by @swiftlyfalling.
    • 📚 FetchedRecordsController can now fetch other values alongside the fetched records. This grants you the ability to fetch values that are consistent with the notified changes. (documentation)

    💥 Breaking Changes

    • 👍 iOS7 is no longer supported.

  • v0.70.1 Changes

    🚀 Released May 30, 2016

    🛠 Fixed

    • ⚡️ Database.cachedUpdateStatement(sql) no longer returns a statement that can not be reused because it has already failed.

  • v0.70.0 Changes

    🚀 Released May 28, 2016

    🆕 New

    • 📚 Database.inSavepoint() allows fine-grained committing and rollbacking of database statements (documentation). Closes #61.

  • v0.69.0 Changes

    🚀 Released May 28, 2016

    🛠 Fixed

    • 🚀 Database changes that are on hold because of a savepoint are only notified to transaction observers after the savepoint has been released. In previous versions of GRDB, savepoints had the opportunity to rollback a subset of database events, and mislead transaction observers about the actual content of a transaction. Related issue: #61.

    🆕 New

    • 📚 DatabaseEvent.copy() lets you store a database event notified to a transaction observer (documentation).

  • v0.68.0 Changes

    🚀 Released May 28, 2016

    🆕 New

    🚀 This release provides tools for your custom persistence mechanisms that don't use the built-in Persistable protocol, and addresses issue #60.

    • 📚 Database.primaryKey(tableName) lets you introspect a table's primary key (documentation).
    • 📚 Database.cachedSelectStatement(sql) and Database.cachedUpdateStatement(sql) provide robust caching of prepared statements (documentation)
