Create a project

Create a project to get started: Sendbird for iOS supports both Objective-C and Swift.

Install SDK via CocoaPods or Carthage

Installing the Chat SDK is a simple process if you’re familiar with using external libraries or SDK’s in your projects. You can install the Chat SDK using CocoaPods or Carthage like the following.

- CocoaPod

Open a terminal window. Navigate to the project directory, and then open the Podfile by running the following command:

$ pod init

On Podfile, add the following lines:

platform :ios, '9.0'
use_frameworks!

target YOUR_PROJECT_TARGET do
    pod 'SendBirdSDK', '~> 3.1.0'
end

Install the SendBird framework through CocoaPods.

$ pod install

Now you can run your project with the SendBird framework by opening *YOUR_PROJECT*.xcworkspace. If you don't want to use CocoaPods, check out the manual installation guide.

- Carthage

Add github "sendbird/sendbird-ios-framework" to your Cartfile.
Run carthage update.
Go to your Xcode project's General settings tab. Open the <YOUR_XCODE_PROJECT_DIRECTORY>/Carthage/Build/iOS in the Finder window and drag SendBirdSDK.framework to the Embedded Binaries section in Xcode. Make sure the Copy items if needed option is selected and click Finish.
On your application targets’ Build Phases settings tab, click the + icon and choose New Run Script Phase. Create a Run Script in which you specify your shell (ex: /bin/sh), add the following contents 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/SendBirdSDK.framework
