Unexpectedly found nil while initialising the VisionReplayManager

let documentsPath =
NSSearchPathForDirectoriesInDomains(.documentDirectory,
.userDomainMask,
true).first!
let path = documentsPath.appending("/safety-alerts-drawing")

    // create VisionReplayManager with a path to recorded session
    visionManager = try? VisionReplayManager.create(recordPath: path)

Hey @cisnayan. Were you able to download the session and put it in the right place as described in the tutorial?

Yes @chezzdev I just follow the same code and try to run the same but when i debug i got to know that the visionManager is nil and crashed when we try to assign the delegate of it.
As the VisionReplayManager returning the nil object.

You need to download the recorded session and put it on the device. Please follow the instructions at https://docs.mapbox.com/help/tutorials/ios-vision-safety-alerts/#getting-started.
