Integrate the SDK

Set up the development environment

Before integrating the ZEGO Express SDK, make sure the development environment meets the following requirements:

• Xcode 13.0 or later
• An iOS device or iOS Simulator that is running on iOS 9.0 or later and supports audio and video. We recommend you use a real device.
• The iOS device is connected to the internet.

Create a new project

Skip this step if a project already exists.

Create a new project

1. Open Xcode, and in the Welcome to Xcode window, click Create a new Xcode project or select File > New > Project. In the dialog that appears, select the iOS tab, then select App in the Application section.
   

2. Fill in items or choose options for the new project, click Next after configuration is completed.

Product Name and Organization Identifier are required, which will be used for creating the App UID - Bundle Identifier.

3. Choose a particular directory to restore the project to be created, and click Create to create a project.
   

Import the SDK

Choose either of the following methods to integrate the ZEGO Express SDK into your project.

Method 1: Integrate the SDK automatically with CocoaPods

1. Install CocoaPods. For more details, see CocoaPods Installation Guide .

2. Open the Terminal, enter the root directory of the project, and execute the command pod init to create a Podfile.

3. Open Podfile, add pod 'ZegoExpressEngine/Video', and change MyProject to your target name.

target 'MyProject' do
  use_frameworks!
  pod 'ZegoExpressEngine/Video'
end

4. Execute pod repo update to update the local index to make sure the latest version of SDK can be installed. For the latest version number, see ZEGO Express-Video iOS SDK Release History .

5. Execute pod install to install the SDK.

   For common problems you may encounter when using CocoaPods, see CocoaPods FAQ .

Method 2: Manually add the SDK to the project

1. Download the latest version of SDK from SDK downloads . We recommend you use XCFramework, and then extract files from the downloaded SDK package.

2. Copy the SDK dynamic library file ZegoExpressEngine.framework to the project directory.

   • ios-arm64_armv7: A real device that supports the arm64 or armv7 architectures of the iOS platform.
   • ios-arm64_x86_64-maccatalyst: supports the arm64, x86_64 architecture of Mac Catalyst mode.
   • ios-arm64_x86_64-simulator: A simulator that supports the arm64 and x86_64 architectures of the iOS platform.

3. Open Xcode and select File > Add Files to "xxx" (xxx is the project name) to add the SDK dynamic library files to the project.

4. Do the following to add the framework file to the project target.

   a) Select the project target.

   b) Click General, then under Frameworks, Libraries, and Embedded Content, click the Add button (+) below the table.

   c) Add ZegoExpressEngine.framework to the target, and set the Embed field to Embed & Sign.

   

Add permissions

Permissions can be set as needed.

1. Open Xcode, select the target object, and then click Info > Custom iOS Target Properties.

2. Click the Add button (+) to add camera and microphone permissions.

FAQ

1. The error occurs when packaging the app: Failed to verify bitcode in ZegoExpressEngine.framework/ZegoExpressEngine.

   Recommendations:
   a. Check whether the Xcode version is too low. We recommend updating the latest Xcode version.
   b. If you have to use the old version of Xcode for packaging, find the Enable Bitcode option in the project's Build Setting and set it to NO, and open the terminal to execute cd DIRECTORY to go to the directory where ZegoExpressEngine.framework is stored in your project, and then execute the following command to remove the bitcode in the SDK：

   xcrun bitcode_strip ZegoExpressEngine.framework/ZegoExpressEngine -r -o ZegoExpressEngine.framework/ZegoExpressEngine
