i faced a such issue and i made this: create CIContext in SampleHandler.init()      if let metalDevice = MTLCreateSystemDefaultDevice() {       coreImageContext = CIContext(mtlDevice: metalDevice)     } else {       coreImageContext = CIContext(options: nil)     } 2. add rotate method private func rotate(_ sampleBuffer: CMSampleBuffer) -> CVPixelBuffer? {     guard let pixelBuffer = CMSampleBufferGetImageBuffer(sampleBuffer) else {       return nil     }     var newPixelBuffer: CVPixelBuffer?     let error = CVPixelBufferCreate(kCFAllocatorDefault,                     CVPixelBufferGetHeight(pixelBuffer),                     CVPixelBufferGetWidth(pixelBuffer),                     kCVPixelFormatType_420YpCbCr8BiPlanarFullRange,                     nil,                     &newPixelBuffer)     guard error == kCVReturnSuccess,        let buffer = newPixelBuffer else {       return nil     }     let ciImage = CIImage(cvPixelBuffer: pixelBuffer).oriented(.left)     coreImageContext.render(ciImage, to: buffer)     return buffer   } 3. use the rotate() method in processSampleBuffer and send rotated buffer to a streaming-service

I met that situation. So i understood that broadcast-extension terminated earlier than system alert will be appeared. please check my solution: 1 - create property of SampleHandler private var startedWithError: BroadcastError? = nil 2 - set this error in streamStarted method override func broadcastStarted(withSetupInfo setupInfo: [String : NSObject]?) {     guard let streamingSession = streamingSession else {       startedWithError = .failedInitStreamingService       return     } 		// some success code here } 3 - check error in processSampleBuffer    override func processSampleBuffer(_ sampleBuffer: CMSampleBuffer, with sampleBufferType: RPSampleBufferType) {           if let error = startedWithError {       finishBroadcastWithError(error.nsError)     } P.S. Also you can use DispatchQueue.global.asyncAfter(.now()+0.5){ self.finishBroadcastWithError(error.nsError) } in broadcastStarted
