CameraView by Mijick is a powerful, open-source library that simplifies the camera presentation process, making it super fast and totally customisable, allowing you to focus on the important elements of your project while hiding the technical complexities.

  • Customise your UI completely. Use a clean and modern UI we designed or change it completely within minutes!
  • Covers the entire process. Our library both presents the camera controller, asks for permissions, displays an error view if permissions are not granted, and shows the result of the capture in a separate view (if you wish, of course).
  • Improves code quality. Allows you to focus on the most important things, hiding implementation details inside this powerful library.
  • Designed for SwiftUI. As we developed the library, we utilized SwiftUI's capabilities to offer you a powerful tool for streamlining your implementation process.

Getting Started

✋ Requirements

Platforms Minimum Swift Version
iOS 14+ 5.10

⏳ Installation

Swift Package Manager is a tool for automating the distribution of Swift code and is integrated into the Swift compiler.

Once you have your Swift package set up, adding PopupView as a dependency is as easy as adding it to the dependencies value of your Package.swift.

dependencies: [
    .package(url: "https://github.com/Mijick/CameraView.git", branch(“main”))
]

Cocoapods is a dependency manager for Swift and Objective-C Cocoa projects that helps to scale them elegantly.

Installation steps:

    pod init
  • Add CocoaPods dependency into your Podfile
    pod 'MijickCameraView'
  • Install dependency and generate .xcworkspace file
    pod install
  • Use new XCode project file .xcworkspace

Usage

1. Modify the info.plist file

Open the info.plist file of your project. Add two new keys: Privacy - Microphone Usage Description and Privacy - Camera Usage Description. Value will be displayed by default in the error screen when the user denies access to one of the above permissions.

2. Insert MCameraController into the selected view

MCameraController contains three screens - CameraView, CameraPreview (which can be turned off) and CameraErrorView. Therefore, we advise that there should be no other elements in the view where you declare MCameraController. We’ve designed this system around the experience and needs of ourselves and the developers we know. However, if your preferences are different, we are happy to meet your expectations and adapt our library. Share them with us by creating an issue for this project.

struct CameraView: View {

    (...)
   
    var body: some View {
        MCameraController()
    }

    (...)
}

3. Declare onImageCaptured, onVideoCaptured, afterMediaCaptured and onCloseController

The above functions define what happens after a given action and are optional; for example, if your application only captures images, you don't need to declare onVideoCaptured and so on.

struct CameraView: View {

    (...)
   
    var body: some View {
        MCameraController()
            .onImageCaptured { data in
                print("IMAGE CAPTURED")
            }
            .onVideoCaptured { url in
                print("VIDEO CAPTURED")
            }
            .afterMediaCaptured {
                print("IMAGE OR VIDEO WAS PROCESSED. WHAT'S NEXT?")
            }
            .onCloseController {
                print("CLOSE THE CONTROLLER")
            }
    }

    (...)
}

4. (Optional) Block screen rotation for MCameraController

CameraView library by Mijick, allows you to lock the screen rotation for MCameraController, even if a device rotation is unlocked. To achieve it, create an AppDelegate class conforming to MApplicationDelegate, declare @UIApplicationDelegateAdaptor in @main struct and set lockOrientation(AppDelegate.self) for MCameraController.

class AppDelegate: NSObject, MApplicationDelegate {
    static var orientationLock = UIInterfaceOrientationMask.all

    func application(_ application: UIApplication, supportedInterfaceOrientationsFor window: UIWindow?) -> UIInterfaceOrientationMask { AppDelegate.orientationLock }
}
@main struct CameraView_DemoApp: App {
    @UIApplicationDelegateAdaptor(AppDelegate.self) var appDelegate

    var body: some Scene {
        WindowGroup(content: CameraView.init)
    }
}
struct CameraView: View {

    (...)
   
    var body: some View {
        MCameraController()
            .lockOrientation(AppDelegate.self)
    }

    (...)
}

5. (Optional) Change the initial camera settings

You can change the initial camera settings using the modifiers from the list below:

struct CameraView: View {

    (...)
   
    var body: some View {
        MCameraController()
            .outputType(.video)
            .cameraPosition(.front)
            .flashMode(.auto)
            .gridVisible(false)
            .focusImage(.init(named: "icon-focus")!)
            .focusImageColor(.blue)
            .focusImageSize(120)
    }

    (...)
}

6. (Optional) Change CameraView UI

You can change the appearance of the CameraView by creating a new structure, conforming to MCameraView and using the cameraScreen modifier.

struct CustomCameraView: MCameraView {
    @ObservedObject var cameraManager: MijickCameraView.CameraManager
    let namespace: Namespace.ID
    let closeControllerAction: () -> ()


    var body: some View {
        VStack(spacing: 0) {
            createNavigationBar()
            createCameraView()
            createCaptureButton()
        }
    }
}
private extension CustomCameraView {
    func createNavigationBar() -> some View {
        Text("This is a Custom Camera View")
            .padding(.top, 12)
            .padding(.bottom, 12)
    }
    func createCaptureButton() -> some View {
        Button(action: captureOutput) { Text("Click to capture") }
            .padding(.top, 12)
            .padding(.bottom, 12)
    }
}
struct CameraView: View {

    (...)
   
    var body: some View {
        MCameraController()
            .cameraScreen(CustomCameraView.init)
    }

    (...)
}

7. (Optional) Change (or disable) CameraPreview UI

You can change the appearance of the CameraPreview by creating a new structure, conforming to MCameraPreview and using the mediaPreviewScreen modifier.
Note: To disable the preview of captured media, use the mediaPreviewScreen modifier with nil as the argument.

struct CustomCameraPreview: MCameraPreview {
    let capturedMedia: MijickCameraView.MCameraMedia
    let namespace: Namespace.ID
    let retakeAction: () -> ()
    let acceptMediaAction: () -> ()


    var body: some View {
        VStack(spacing: 0) {
            Spacer()
            createContentView()
            Spacer()
            createButtons()
        }
    }
}
private extension CustomCameraPreview {
    func createContentView() -> some View { ZStack {
        if let image = capturedMedia.image { createImageView(image) }
        else { EmptyView() }
    }}
    func createButtons() -> some View {
        HStack(spacing: 24) {
            createRetakeButton()
            createSaveButton()
        }
    }
}
private extension CustomCameraPreview {
    func createImageView(_ image: Data) -> some View {
        Image(uiImage: .init(data: image) ?? .init())
            .resizable()
            .aspectRatio(contentMode: .fit)
            .ignoresSafeArea()
    }
    func createRetakeButton() -> some View {
        Button(action: retakeAction) { Text("Retake") }
    }
    func createSaveButton() -> some View {
        Button(action: acceptMediaAction) { Text("Save") }
    }
}
struct CameraView: View {

    (...)
   
    var body: some View {
        MCameraController()
            .mediaPreviewScreen(CustomCameraPreview.init)
    }

    (...)
}

8. (Optional) Change CameraErrorView UI

You can change the appearance of the CameraErrorView by creating a new structure, conforming to MCameraErrorView and using the errorScreen modifier.

struct CustomCameraErrorView: MCameraErrorView {
    let error: CameraManager.Error
    let closeControllerAction: () -> ()


    var body: some View {
        Button(action: openAppSettings) { Text("Open Settings") }
    }
}
struct CameraView: View {

    (...)
   
    var body: some View {
        MCameraController()
            .errorScreen(CustomCameraErrorView.init)
    }

    (...)
}
