SwiftyCam: A Snapchat inspired iOS Camera Framework Written In Swift

Overview

SwiftyCam is a a simple, Snapchat-style iOS Camera framework for easy photo and video capture. SwiftyCam allows users to capture both photos and videos from the same session with very little configuration.

Configuring a Camera View Controller in AVFoundation can be tedious and time consuming. SwiftyCam is a drop in View Controller which gives complete control of the AVSession.

For Swift 4 support, see Swift4 branch

License

SwiftyCam is available under the BSD license. See the LICENSE file for more info.

Installation

Cocoapods:

SwiftyCam is available through CocoaPods. To install it, simply add the following line to your Podfile:

pod "SwiftyCam"

Carthage

Add this to Cartfile

github "Awalz/SwiftyCam" ~> 2.2.1

$ carthage update SwiftyCam

Manual Installation:

Simply copy the contents of the Source folder into your project.

Usage

Using SwiftyCam is very simple.

Prerequisites:

As of iOS 10, Apple requires the additon of the NSCameraUsageDescription and NSMicrophoneUsageDescription strings to the info.plist of your application. Example:

<key>NSCameraUsageDescription</key>
    <string>To Take Photos and Video</string>
<key>NSMicrophoneUsageDescription</key>
    <string>To Record Audio With Video</string>

Getting Started:

If you install SwiftyCam from Cocoapods, be sure to import the module into your View Controller:

import SwiftyCam

SwiftyCam is a drop-in convenience framework. To create a Camera instance, create a new UIViewController subclass. Replace the UIViewController subclass declaration with SwiftyCamViewController:

class MyCameraViewController : SwiftyCamViewController

That is all that is required to setup the AVSession for photo and video capture. SwiftyCam will prompt the user for permission to use the camera/microphone, and configure both the device inputs and outputs.

Capture

SwiftyCamButton:

SwiftyCam comes with a very convenient method of capturing media. SwiftyCamButton captures photos with a UITapGestureRecognizer and captures video with a UILongPressGestureRecognizer

To use a SwiftyCamButton, simply create one and assign the delegate to your SwiftyCamViewController:

let captureButton = SwiftyCamButton(frame: buttonFrame)
captureButton.delegate = self

Manual:

Capturing media with SwiftyCam is very simple. To capture a photo, simply call the takePhoto function:

takePhoto()

Capturing Video is just as easy. To begin recording video, call the startVideoRecording function:

startVideoRecording()

To end the capture of a video, call the stopVideoRecording function:

stopVideoRecording()

Delegate

In order to acquire the photos and videos taken by either the SwiftyCamButton or manually, you must implement the SwiftyCamViewControllerDelegate and set the cameraDelegate to your view controller instance:

class MyCameraViewController : SwiftyCamViewController, SwiftyCamViewControllerDelegate {

    override func viewDidLoad() {
        super.viewDidLoad()
        cameraDelegate = self
    }
    ...
}

Delegate methods:

func swiftyCam(_ swiftyCam: SwiftyCamViewController, didTake photo: UIImage) {
     // Called when takePhoto() is called or if a SwiftyCamButton initiates a tap gesture
     // Returns a UIImage captured from the current session
}

func swiftyCam(_ swiftyCam: SwiftyCamViewController, didBeginRecordingVideo camera: SwiftyCamViewController.CameraSelection) {
     // Called when startVideoRecording() is called
     // Called if a SwiftyCamButton begins a long press gesture
}

func swiftyCam(_ swiftyCam: SwiftyCamViewController, didFinishRecordingVideo camera: SwiftyCamViewController.CameraSelection) {
     // Called when stopVideoRecording() is called
     // Called if a SwiftyCamButton ends a long press gesture
}

func swiftyCam(_ swiftyCam: SwiftyCamViewController, didFinishProcessVideoAt url: URL) {
     // Called when stopVideoRecording() is called and the video is finished processing
     // Returns a URL in the temporary directory where video is stored
}

func swiftyCam(_ swiftyCam: SwiftyCamViewController, didFocusAtPoint point: CGPoint) {
     // Called when a user initiates a tap gesture on the preview layer
     // Will only be called if tapToFocus = true
     // Returns a CGPoint of the tap location on the preview layer
}

func swiftyCam(_ swiftyCam: SwiftyCamViewController, didChangeZoomLevel zoom: CGFloat) {
      // Called when a user initiates a pinch gesture on the preview layer
      // Will only be called if pinchToZoomn = true
      // Returns a CGFloat of the current zoom level
}

func swiftyCam(_ swiftyCam: SwiftyCamViewController, didSwitchCameras camera: SwiftyCamViewController.CameraSelection) {
     // Called when user switches between cameras
     // Returns current camera selection   
}

Flash

The flash(torch) can be enabled by changing the flashEnabled property:

flashEnabled = true

Flash is now supported for front and rear facing cameras.

Rear Camera

For photos, the camera will flash much like the stock iOS camera. For video, the torch(flash) will enable for the duration of the video capture.

Front Camera

For models that support Retina Flash, the front camera will use the default flash for image capture. If Retina Flash is not supported, a faux Retina Flash is used similar to Snapchat.

For front facing videos, a white, 85% opaque view will be placed over the video feed for the duration of the video capture.

Switching Camera

By default, SwiftyCam will launch to the rear facing camera. This can be changed by changing the defaultCamera property in viewDidLoad:

override func viewDidLoad() {
    super.viewDidLoad()
    defaultCamera = .front
    ...
}

SwiftyCam supports capture from both the front and back cameras. To switch cameras, call the function:

switchCamera()

Tap-to-focus, pinch-to-zoom and camera flash are not supported when the front facing camera is selected. Switching video while video is being recorded is not currently supported

SwiftyCam also enables switching between cameras with a double tap gesture. To disable this feature, use the doubleTapCameraSwitch property:

doubleTapCameraSwitch = false

Configuration

SwiftyCam has several options for configurating the functionality of the capture:

Video Quality

Video quality can be set by the videoQuality property of SwiftyCamViewController. The choices available correspond to the matching AVCaptureSessionPreset:

VideoQualityAVCaptureSessionPreset
.highAVCapturePresetHigh
.mediumAVCapturePresetMedium
.lowAVCapturePresetLow
.resolution352x288AVCaptureSessionPreset352x288
.resolution640x480AVCaptureSessionPreset640x480
.resolution1280x720AVCaptureSessionPreset1280x720
.resolution1920x1080AVCaptureSessionPreset1920x1080
.resolution3840x2160AVCaptureSessionPreset3840x2160
.iframe960x540AVCaptureSessionPresetiFrame960x540
.iframe1280x720AVCaptureSessionPresetiFrame1280x720

The default value is .high. For use with the front-facing camera, .high will always be used.

Maximum Video Duration

If using a SwiftyCamButton, you can set a maximum video duration for the length of video. The video recording will me automatically stopped once the time limit has been reached and the delegate method SwiftyCamDidFinishRecordingVideo will be called. To set this value, simply change the maximumVideoDuration value:

maximumVideoDuration = 10.0

A value of 0.0 will allow for unlimited video recording via the SwiftyCamButton. The default value is 0.0.

Camera Zoom

SwiftyCam supports digital zoom of the camera session via pinch and pan gestures. The gestures work similar to the default iOS app and will zoom to the maximum supported zoom level. Camera zoom is only supported on the rear facing camera. AVFoundation does not currently support front facing camera zoom. To disable this feature, change the pinchToZoom property:

pinchToZoom = false

By default, pinchToZoom is enabled.

SwiftyCam also supports the ability to zoom the rear facing camera with vertical pan gestures. To disable this feature, change the swipeToZoom property:

swipeToZoom = false

By default, swipeToZoom is enabled. The default gestures zoom in the capture session with a downward swipe, and zoom out with an upward swipe. This can be reversed by changing the swipeToZoomInverted property:

swipeToZoomInverted = true

You can also restrict the amount that the rear facing camera can zoom. To do this, use the maxZoomScale property:

maxZoomScale = 2.0

By default, maxZoomScale is set to infinite. The actual maximum zoom level is determined by the device's videoMaxZoomFactor.

Camera Focus

SwiftyCam, by default, support tap to focus on the video preview. SwiftyCam will set the focus and exposure levels of the session to the tapped point. While tap to set exposure is supported on both cameras, tap to focus is only supported on rear facing cameras. Autofocus and autoexposure will be resumed once SwiftyCam detects significant movement from the tapped point. To disable this feature, change the tapToFocus property:

tapToFocus = false

By default, tapToFocus is enabled. If you wish to show a on screen animation when a tap to focus is initiated, you can use the SwiftyCamDidFocusAtPoint(focusPoint:) to get the coordinates of tap and provide your own tap animation

Device Orientation

By default, SwiftyCam will set the photo orientation to be portrait. If you wish to preserve the orientation of the capture photos to allow support for landscape images, use the shouldUseDeviceOrientation property:

shouldUseDeviceOrientation = true

Background Audio

SwiftyCam has the ability to allow background audio to continue playing within the session, and to be captured by the video recording. By default, this is enabled. If you wish to disable this feature, change the allowBackgroundAudio property:

allowBackgroundAudio = false

Low Light Boost

For supported models (iPhone 5 and 5C), AVCaptureDevice supports a low light boost when it is detected that the capture session is in a low light area. By default, this is set to true. It can be modified with the lowLightBoost variable:

lowLightBoost = false

Privacy

When a user firsts launch SwiftyCamViewController, they will be prompted for permission for access to the cameras and microphones. By default, if a user declines access to the hardware, SwiftyCam will provide a prompt to the App privacy settings inside the iOS settings application.

Miscellaneous

Other properties:

  • isCameraFlashOn - Boolean
  • isVideoRecording - Boolean
  • isSessionRunning - Boolean
  • currentCamera - CameraSelection

Images

First App Store screenshot Second App Store screenshot Third App Store screenshot Fourth App Store screenshot Fifth App Store screenshot

Building

Automatic setup

The easiest way to setup the dependencies of the project and generate the Xcode project is to run sh scripts/setup.sh from the top of the repository.

Manual setup

If you prefer to not use the sh scripts/setup.sh script and install the dependencies yourself, follow the instructions below.

We use Carthage for dependency management.

Run carthage bootstrap --platform iOS --cache-builds before opening the project in Xcode.

You can install Carthage with Homebrew:

brew install carthage

To generate the Xcode project run sh scripts/create-project.sh. In order to generate the Xcode project we use XcodeGen.

Carthage resources

New to Carthage? Others have found the following resources helpful:

Fastlane

Currently there are two lanes, one for running the tests (fastlane test) and one for uploading a new beta to TestFlight (fastlane beta).

You can install Fastlane with Homebrew:

brew cask install fastlane

Generating screenshots

fastlane snapshot

Roadmap on automatic screenshot generation:

  •  fixing the non translatable scan product button so that the screenshot and the app are fully translated
  •  fixing the Scan screenshot generation, and adding a way to set the background of the barcode scanner with an arbitrary image, per country
  •  fixing History screenshot population with products
  •  Adding the proposed fix to clean the top bar with 100% battery, and a fixed time
  •  Adding fastlane frameit to the Fastlane file, so that we can get versions wrapped in physical devices
  •  fixing Chinese screenshot generation
  •  Ensure we can generate for 1 of (iPhone 11 Pro Max, iPhone 11, iPhone XS Max, iPhone XR), 1 of (iPhone 6s Plus, iPhone 7 Plus, iPhone 8 Plus), 1 of (3rd generation iPad Pro)
  •  Extra: For debugging purposes, it would be great to have other screen resolutions (iPhone 11 Pro, iPhone X, iPhone XS) (iPhone 6, iPhone 6s, iPhone 7, iPhone 8) (iPhone SE) (iPhone 4s)

SwiftLint

We have a script that runs when building the app, it executes SwiftLint to enforce a style and conventions to the code.

You can install SwiftLint with Homebrew:

brew install swiftlint
