I am developing a camera app by using Xcode ver.1.12.5 and SwiftUI (for iPhone8). The functions of the app are capturing a photo with front camera and saving the photos to Camera Roll. I’d like to add functions to realize (1) delayed shooting with (2) displaying remaining time. Could you tell me the code for above (1) and (2)?Thank you for your kindly support in advance.

We apologize for asking questions using Google Translate. I'm currently developing a photography app with XCode, what code should I write to add the ability to automatically release the shutter over time? If anyone knows, wouldn't you like to ask for a professor?
