Usage

Using the Module

Object Initialization

import SwiftUICam

let camera = CameraWrapper()

Setting the view

To set the view, first create a structure that inhertits UIViewRepresentable.
This protocol states that you must implement two functions - MakeUIView & UpdateUIView.
MakeUIView - Sets the view (basically ViewDidLoad)
UpdateUIView - Updates after user input (viewDidChange)
To make these functions work with this framework, we will need to pass an instance of CameraWrapper and a view of type UIView.
We also want to declare the a UIView variable that will be used to specify the frame in which this view will sit.
Upon declaring these protocol functions and variables we can use the CameraWrapper to call the public preview setup functions as shown below.

import SwiftUICam

struct SwiftUICamPreview: UIViewRepresentable {
    
    @ObservedObject var camera: CameraWrapper
    var view: UIView

    func makeUIView(context: Context) ->  UIView {
        return camera.makeUIView(view)
    }

    func updateUIView(_ uiView: UIView, context: Context) { }
}
