Branch plugin

Use this Fastlane plugin to set up your Xcode project configuration correctly to use the Branch SDK. It can also validate the Universal Link configuration in any Xcode project, for Branch domains as well as non-Branch domains. Unlike web-based Universal Link validators, the validate_universal_links action operates directly on your project. There is no need to look up your team identifier or any other information. The validator requires no input at all for simple projects. It supports both signed and unsigned apple-app-site-association files.

Also see the Branch CLI, which supports the same operations without Fastlane.

Preliminary release

This is a preliminary release of this plugin. Please report any problems by opening issues in this repo.

Getting Started

This project is a fastlane plugin. To get started with fastlane-plugin-branch, add it to your project by running:

fastlane add_plugin branch

setup_branch action

setup_branch

Integrates the Branch SDK into a native app project. This currently supports iOS only. It will infer the project location if there is exactly one .xcodeproj anywhere under the current directory, excluding any in a Pods or Carthage folder. Otherwise, specify the project location using the xcodeproj option, or the CLI will prompt you for the location.

If a Podfile or Cartfile is detected, the Branch SDK will be added to the relevant configuration file and the dependencies updated to include the Branch framework. This behavior may be suppressed using no_add_sdk. If no Podfile or Cartfile is found, and Branch.framework is not already among the project's dependencies, you will be prompted for a number of choices, including setting up CocoaPods or Carthage for the project or directly installing the Branch.framework.

By default, all supplied Universal Link domains are validated. If validation passes, the setup continues. If validation fails, no further action is taken. Suppress validation using no_validate or force changes when validation fails using force.

By default, this command will look for the first app target in the project. Test targets are not supported. To set up an extension target, supply the target option.

All relevant target settings are modified. The Branch keys are added to the Info.plist, along with the branch_universal_link_domains key for custom domains (when domains is used). For app targets, all domains are added to the project's Associated Domains entitlement. An entitlements file is also added for app targets if none is found. Optionally, if frameworks is specified, this command can add a list of system frameworks to the target's dependencies (e.g., AdSupport, CoreSpotlight, SafariServices).

A language-specific patch is applied to the AppDelegate (Swift or Objective-C). This can be suppressed using no_patch_source.

Prerequisites

Before using this command, make sure to set up your app in the Branch Dashboard (https://dashboard.branch.io). See https://docs.branch.io/pages/dashboard/integrate/ for details. To use the setup command, you need:

• Branch key(s), either live, test or both
• Domain name(s) used for Branch links
• Location of your Xcode project (may be inferred in simple projects)

If using the commit option, git is required. If not using no_add_sdk, the pod or carthage command may be required. If not found, the CLI will offer to install and set up these command-line tools for you. Alternately, you can arrange that the relevant commands are available in your PATH.

All parameters are optional. A live key or test key, or both is required, as well as at least one domain. Specify live_key, test_key or both and app_link_subdomain, domains or both. If these are not specified, this command will prompt you for this information.

See https://github.com/BranchMetrics/branch_io_cli#setup-command for more information.

  uri_scheme: "myscheme",
  xcodeproj: "MyIOSApp.xcodeproj"
)

validate_universal_links action

validate_universal_links

This command validates all Universal Link domains configured in a project without making any modification. It validates both Branch and non-Branch domains. Unlike web-based Universal Link validators, this command operates directly on the project. It finds the bundle and signing team identifiers in the project as well as the app's Associated Domains. It requests the apple-app-site-association file for each domain and validates the file against the project's settings.

Only app targets are supported for this command. By default, it will validate the first. If your project has multiple app targets, specify the target option to validate other targets.

All parameters are optional. If domains is specified, the list of Universal Link domains in the Associated Domains entitlement must exactly match this list, without regard to order. If no domains are provided, validation passes if at least one Universal Link domain is configured and passes validation, and no Universal Link domain is present that does not pass validation.

See https://github.com/BranchMetrics/branch_io_cli#validate-command for more information.
