Go to ZEGOCLOUD Admin Console, get the appID and appSign of your project.
Specify the userID and userName for connecting the Live Streaming Kit service.
liveID Represents the live streaming you want to start or watch (only supports single-host live streaming for now).

// YourViewController.swift
class MainViewController: UIViewController {
    // Other code...
    var userID: String = <#UserID#>
    var userName: String = <#UserName#>
    var liveID: String = <#liveID#>
 
func startLive() {
        let config: ZegoUIKitPrebuiltLiveStreamingConfig = ZegoUIKitPrebuiltLiveStreamingConfig(kPresetRoleHost)
        let liveVC: ZegoUIKitPrebuiltLiveStreamingVC = ZegoUIKitPrebuiltLiveStreamingVC(yourAppID, appSign: yourAppSign, userID: self.userID, userName: self.userName, liveID: self.liveID, config: config)
        liveVC.modalPresentationStyle = .fullScreen
        self.present(liveVC, animated: true, completion: nil)
}
 
func watchLive() {
      let config: ZegoUIKitPrebuiltLiveStreamingConfig = ZegoUIKitPrebuiltLiveStreamingConfig(kPresetRoleAudience)
      let liveVC: ZegoUIKitPrebuiltLiveStreamingVC = ZegoUIKitPrebuiltLiveStreamingVC(yourAppID, appSign: yourAppSign, userID: self.userID, userName: self.userName, liveID: self.liveID, config: config)
      liveVC.modalPresentationStyle = .fullScreen
      self.present(liveVC, animated: true, completion: nil)
}
 
}

Then, you can begin to live streaming by presenting the liveVC.
