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) { }
}
