Facebook SDK in Swift (Beta)

Swift-taylored experience to integrate your app with Facebook. Including:

• Facebook Login - Authenticate people with their Facebook credentials.
• Share and Send Dialogs - Enable sharing content from your app to Facebook.
• App Events - Understand your audience and the performance of your app.
• Graph API - Read and write directly to Facebook social graph.

Getting Started

• CocoaPods

  • Make sure you are running the latest version of CocoaPods by running:

    gem install cocoapods
    # (or if the above fails)
    sudo gem install cocoapods

    We support any version of CocoaPods 1.0.1 or later.

  • Update your local specs repo by running:

    pod repo update

    This step is optional, if you updated the specs repo recently.

  • Add the following lines to your Podfile:

    pod 'FacebookCore'
    pod 'FacebookLogin'
    pod 'FacebookShare'

  • Run pod install

  • You are all set!

You may also exclude any of these dependencies, if you do not need the features of those parts of the SDK.

• Carthage

  • Make sure you are running the latest version of Carthage by running:

    brew update
    brew upgrade carthage

    We recommend using Carthage version 0.17.2 or later.

  • Add the following line to your Cartfile:

    github "facebook/Facebook-SDK-Swift"
    

  • Run carthage update.
    This will fetch dependencies into a Carthage/Checkouts folder, then build each one.

  • On your application targets' General settings tab, in the Linked Frameworks and Libraries section:

    • Drag & drop the following frameworks from Carthage/Build folder on disk:
    • At a minimum:
      • FacebookCore.framework
      • FBSDKCoreKit.framework
      • Bolts.framework
    • To use Login with Facebook:
      • FacebookLogin.framework
      • FacebookCore.framework (and it's dependencies)
    • To use Share and Send Dialogs
      • FacebookShare.framework
      • FacebookCore.framework (and it's dependencies)

  • On your application targets' Build Phases tab:

    • Click + icon and choose New Run Script Phase.

    • Create a script with a shell of your choice (e.g. /bin/sh).

    • Add the following to the script area below the shell:

      /usr/local/bin/carthage copy-frameworks
      

    • Add the paths to the frameworks you want to use under Input Files, for example:

      $(SRCROOT)/Carthage/Build/iOS/FacebookCore.framework
      $(SRCROOT)/Carthage/Build/iOS/FBSDKCoreKit.framework
      $(SRCROOT)/Carthage/Build/iOS/Bolts.framework
      

• Using Facebook SDK as a sub-project

  While not recommended, it is entirely possible for you to build the Facebook SDK for Swift outside of any dependency management system.

  Note that you will have to manage updating this solution (as well as the dependencies on the Facebook SDK for iOS) on your own.

  • Clone the repository.
  • Run the following command in the root directory of the repository: git submodule update --init --recursive
  • Add FacebookSwift.xcodeproj as a sub-project to your applications' project.
  • Add the FacebookCore.framework, FacebookLogin.framework, and FacebookShare.framework build products from the sub-project to your applications Link Frameworks and Libraries and Embedded Binaries sections.

  Don't forget to also embed/link FBSDKCoreKit.framework, FBSDKLoginKit.framework, FBSDKShareKit.framework and Bolts.framework too!

Modules

The frameworks for the Facebook SDK in Swift are organized in the same way that the Facebook SDK for iOS is.

They also currently depend upon the Facebook SDK for iOS, although this may change at some point in the future.

FacebookCore

Depends on FBSDKCoreKit.framework and Bolts.framework.

The following types are included, with enhancements for Swift:

• AccessToken
• ApplicationDelegate
• AppEvents

A myriad of improvements, including type-safe built-in AppEvents, an AppEvent struct, and more.

• GraphRequest

You can now implement your own type-safe GraphRequests, including native-typed results.

• SDKSettings

Logging behaviors are now implemented as a type-safe set, based on Swift enums.

• Permission

Are no longer stringly-typed (string-based), but separate types for read and write permissions (also includes a built-in permission list, which includes most common permissions by default).

FacebookLogin

Depends on FacebookCore.framework and FBSDKLoginKit.framework.

The following types are included, with enhancements for Swift:

• LoginManager

Now uses the type-safe permissions from FacebookCore, and has constructors with LoginBehavior and DefaultAudience, instead of requiring manual setting of properties.

• LoginButton

Can no longer change permissions after creation, helping to enforce using a single login button for a given set of permissions. Note that LoginButton is not intended to work with interface builder or storyboards at this time. We may re-address this in the future.

FacebookShare

Depends on FacebookCore.framework and FBSDKShareKit.framework.

The following types are included, with enhancements for Swift:

• LinkShareContent

Now a struct, and has a proper initializer enforcing required properties.

• OpenGraphShareContent

Now a struct, uses type-safe OpenGraphPropertyName and OpenGraphPropertyValue, as well as structs for OpenGraphObject and OpenGraphAction.

• PhotoShareContent

Now a struct, and better type-safety for properties on it.

• VideoShareContent

Now a struct, and better type-safety for properties on it.

• GraphSharer

Now a generic type, that can handle any type of content.

• ShareDialog

Now a generic type, that can handle any type of content.

• MessageDialog

Now a generic type, that can handle any type of content.

• GameRequest

Now a struct, contains proper type-safe enum for Recipient, Result.

• GameRequest.Dialog
• AppGroupRequest.Dialog
• AppInvite

Now a struct, use a type-safe Promotion property, instead of separate promotionCode and promotionText.

• AppInvite.Dialog
