How to Save ReplayKit Video to Camera Roll with In-App Button

Question

I am relatively new to iOS development and Swift but I have an app I\'m working on which is supposed to record the activity on the screen and save the resulting video to the cam

Answer 1

I am running into an error, when it hits:

self.videoWriterInput.markAsFinished();

It is giving me :

-[AVAssetWriterInput markAsFinished] Cannot call method when status is 0
