Using Swift Package Manager to install CouchbaseLiteSwift requires XCode 12+

This tab explains how to include the CouchbaseLiteSwift package within your app
See: Use Case 1. Include in Existing Swift Package | Use Case 2. Include in Your App Project

Use Case 1. Include in Existing Swift Package

Here we will add the CouchbaseLiteSwift dependency to your Parent Swift package — see: Example 1 for the sample manifest.

Add the CouchbaseLiteSwift package as dependency by including the following in the parent package manifest:

dependencies: [
  .package(name: "CouchbaseLiteSwift",
    url: "insert Couchbase Lite URL", (1)
    from: "3.2.2"), (2)
  ],

1	Insert appropriate Couchbase Lite URL: For Community Edition use: https://github.com/couchbase/couchbase-lite-ios.git For Enterprise Edition use: https://github.com/couchbase/couchbase-lite-swift-ee.git
2	Include the required version number here, for example the latest version is 3.2.2

Add the dependent package product name, to the target:

targets: [
  .target(name: "ParentPackage",
    dependencies: ["CouchbaseLiteSwift"]),
  ]

Import CouchbaseLiteSwift, and use it:

import CouchbaseLiteSwift

class ParentPackageSomeClass {
  func someFunction() {
    let db = try! Database(name: "testdb")
    print(">> opening the db: \(db.name)")
  }
}

Example 1. Simple Manifest

// swift-tools-version:5.3
import PackageDescription
let package = Package(
name: "ParentPackage",
products: [
  .library(
    name: "ParentPackage",
    targets: ["ParentPackage"]),
  ],
dependencies: [
  .package(name: "CouchbaseLiteSwift",
    url: "https://github.com/couchbase/couchbase-lite-swift-ee.git", from: "3.2.2"),
  ],
targets: [
  .target(
    name: "ParentPackage",
    dependencies: ["CouchbaseLiteSwift"]),
  .testTarget(
    name: "ParentPackageTests",
    dependencies: ["ParentPackage"]),
  ]
)

Use Case 2. Include in Your App Project

Here we will add CouchbaseLiteSwift directly into your app

Open the project to which you are going to add CouchbaseLiteSwift
Open the Project Editor to add a dependency
1. In Project Navigator:
  Select your Xcode project file (for example, HostApp in the example)
  Xcode opens the Project Editor pane
2. In the Project Editor pane:
  Select Project Swift Packages and + to add the dependency
  Xcode opens the Choose Package Repository dialog
In the Choose Package Repository dialog:
Enter the appropriate Couchbase Lite URL, Next to continue
For example: https://github.com/couchbase/couchbase-lite-swift-ee.git
Enter the required Version (the latest is 3.2.2) and Next to continue
Finish to close the Choose Package Repository dialog

Xcode displays the name, version and URL of the added CouchbaseLiteSwift Package
You can now import CouchbaseLiteSwift, and use it in your app

Install Vector Search Extension

The Vector Search extension is an Enterprise-only feature.

You can get set up with the Vector Search Extension for iOS (Swift) by following these instructions.

To use Vector Search, you must have Couchbase Lite installed and add the Vector Search extension to your Couchbase Lite application. There is no Carthage support for the beta release of Vector Search. Vector Search is available only for 64-bit architectures and Intel processors that support the Advanced Vector Extensions 2 (AVX2) instruction set. To verify whether your device supports the AVX2 instructions set, follow these instructions.

Direct Download

  ],

Add the dependent package product name to the target:

targets: [
  .target(name: "ParentPackage",
     dependencies: ["CouchbaseLiteVectorSearch"]),
]

CouchbaseliteVectorSearch will be automatically detected and loaded in when creating a CouchbaseLite database object.

Use Case 2. Include in Your App Project

Here we will add CouchbaseLiteVectorSearch directly into your app.

Open the project to which you are going to add CouchbaseLiteVectorSearch
Open the Project Editor to add a dependency
1. In Project Navigator:
  Select your XCode project file (for example, HostApp in the example)
  XCode opens the Project Editor pane
2. In the Project Editor pane:

In the Choose Package Repository dialog:
Enter the appropriate Couchbase Lite URL, Next to continue
For Vector Search: https://github.com/couchbase/couchbase-lite-vector-search-spm.git
Enter the required Version (1.0.0) and Next to continue
Finish to close the Choose Package Repository dialog

XCode displays the name, version and URL of the added CouchbaseLiteVectorSearch Package

Finally, you can enable the vector search extension using the following snippet:

        try Extension.enableVectorSearch()

You must enable the extension before you open your database.
