SQLite.swift

Build Status CocoaPods Version Swift5 compatible Platform Carthage compatible Join the chat at https://gitter.im/stephencelis/SQLite.swift

A type-safe, Swift-language layer over SQLite3.

SQLite.swift provides compile-time confidence in SQL statement syntax and intent.

Features

  • A pure-Swift interface
  • A type-safe, optional-aware SQL expression builder
  • A flexible, chainable, lazy-executing query layer
  • Automatically-typed data access
  • A lightweight, uncomplicated query and parameter binding interface
  • Developer-friendly error handling and debugging
  • Full-text search support
  • Well-documented
  • Extensively tested
  • SQLCipher support via CocoaPods
  • Schema query/migration
  • Works on Linux (with some limitations)
  • Active support at StackOverflow, and Gitter Chat Room (experimental)

Usage

import SQLite

// Wrap everything in a do...catch to handle errors
do {
    let db = try Connection("path/to/db.sqlite3")

    let users = Table("users")
    let id = Expression<Int64>("id")
    let name = Expression<String?>("name")
    let email = Expression<String>("email")

    try db.run(users.create { t in
        t.column(id, primaryKey: true)
        t.column(name)
        t.column(email, unique: true)
    })
    // CREATE TABLE "users" (
    //     "id" INTEGER PRIMARY KEY NOT NULL,
    //     "name" TEXT,
    //     "email" TEXT NOT NULL UNIQUE
    // )

    let insert = users.insert(name <- "Alice", email <- "[email protected]")
    let rowid = try db.run(insert)
    // INSERT INTO "users" ("name", "email") VALUES ('Alice', '[email protected]')

    for user in try db.prepare(users) {
        print("id: \(user[id]), name: \(user[name]), email: \(user[email])")
        // id: 1, name: Optional("Alice"), email: [email protected]
    }
    // SELECT * FROM "users"

    let alice = users.filter(id == rowid)

    try db.run(alice.update(email <- email.replace("mac.com", with: "me.com")))
    // UPDATE "users" SET "email" = replace("email", 'mac.com', 'me.com')
    // WHERE ("id" = 1)

    try db.run(alice.delete())
    // DELETE FROM "users" WHERE ("id" = 1)

    try db.scalar(users.count) // 0
    // SELECT count(*) FROM "users"
} catch {
    print (error)
}

SQLite.swift also works as a lightweight, Swift-friendly wrapper over the C API.

// Wrap everything in a do...catch to handle errors
do {
    // ...
    
    let stmt = try db.prepare("INSERT INTO users (email) VALUES (?)")
    for email in ["[email protected]", "[email protected]"] {
        try stmt.run(email)
    }

    db.totalChanges    // 3
    db.changes         // 1
    db.lastInsertRowid // 3

    for row in try db.prepare("SELECT id, email FROM users") {
        print("id: \(row[0]), email: \(row[1])")
        // id: Optional(2), email: Optional("[email protected]")
        // id: Optional(3), email: Optional("[email protected]")
    }

    try db.scalar("SELECT count(*) FROM users") // 2
} catch {
    print (error)
}

Installation

Note: Version 0.11.6 and later requires Swift 5 (and Xcode 10.2) or greater. Version 0.11.5 requires Swift 4.2 (and Xcode 10.1) or greater.

Swift Package Manager

The Swift Package Manager is a tool for managing the distribution of Swift code.

  1. Add the following to your Package.swift file:
dependencies: [
    .package(url: "https://github.com/stephencelis/SQLite.swift.git", from: "0.14.1")
]
  1. Build your project:
$ swift build

See the Tests/SPM folder for a small demo project which uses SPM.

Carthage

Carthage is a simple, decentralized dependency manager for Cocoa. To install SQLite.swift with Carthage:

  1. Make sure Carthage is installed.

  2. Update your Cartfile to include the following:

    github "stephencelis/SQLite.swift" ~> 0.14.1
  3. Run carthage update and add the appropriate framework.

CocoaPods

CocoaPods is a dependency manager for Cocoa projects. To install SQLite.swift with CocoaPods:

  1. Make sure CocoaPods is installed.

    # Using the default Ruby install will require you to use sudo when
    # installing and updating gems.
    [sudo] gem install cocoapods
  2. Update your Podfile to include the following:

    use_frameworks!
    
    target 'YourAppTargetName' do
        pod 'SQLite.swift', '~> 0.14.0'
    end
  3. Run pod install --repo-update.

Manual

To install SQLite.swift as an Xcode sub-project:

  1. Drag the SQLite.xcodeproj file into your own project. (Submodule, clone, or download the project first.)

    Installation Screen Shot

  2. In your target’s General tab, click the + button under Linked Frameworks and Libraries.

  3. Select the appropriate SQLite.framework for your platform.

  4. Add.

Some additional steps are required to install the application on an actual device:

  1. In the General tab, click the + button under Embedded Binaries.

  2. Select the appropriate SQLite.framework for your platform.

  3. Add.
