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.

SwiftyCam is available under the BSD license. See the LICENSE file for more info.
SwiftyCam is available through CocoaPods. To install it, simply add the following line to your Podfile:
pod "SwiftyCam"Simply copy the contents of the Source folder into your project.
Using SwiftyCam is very simple.
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>If you install SwiftyCam from Cocoapods, be sure to import the module into your View Controller:
import SwiftyCamSwiftyCam 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 : SwiftyCamViewControllerThat 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.
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 = selfCapturing 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
}The flash(torch) can be enabled by changing the flashEnabled property:
flashEnabled = trueFlash is now supported for front and rear facing cameras.
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.
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.
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 can be set by the videoQuality property of SwiftyCamViewController. The choices available correspond to the matching AVCaptureSessionPreset:
| VideoQuality | AVCaptureSessionPreset |
|---|---|
.high |
AVCapturePresetHigh |
.medium |
AVCapturePresetMedium |
.low |
AVCapturePresetLow |
.resolution352x288 |
AVCaptureSessionPreset352x288 |
.resolution640x480 |
AVCaptureSessionPreset640x480 |
.resolution1280x720 |
AVCaptureSessionPreset1280x720 |
.resolution1920x1080 |
AVCaptureSessionPreset1920x1080 |
.resolution3840x2160 |
AVCaptureSessionPreset3840x2160 |
.iframe960x540 |
AVCaptureSessionPresetiFrame960x540 |
.iframe1280x720 |
AVCaptureSessionPresetiFrame1280x720 |
The default value is .high. For use with the front-facing camera, .high will always be used.
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 = 10.0A value of 0.0 will allow for unlimited video recording via the SwiftyCamButton. The default value is 0.0.
SwiftyCam supports digital zoom of the camera session via pinch 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 = falseBy default, pinchToZoom is enabled.
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 = falseBy 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
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 = falseFor 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 = falseWhen 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.
