FilterCam is a simple iOS camera framework for recording videos with custom CIFilters applied. Also FilterCam is made very inspired by SwiftyCam.

FilterCam is available through CocoaPods. To install it, simply add the following line to your Podfile:
pod "FilterCam"
Simply copy the contents of the FilterCam folder into your project.
Using FilterCam 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 record video</string>
<key>NSMicrophoneUsageDescription</key>
<string>To record audio with video</string>If you install FilterCam from Cocoapods, be sure to import the module into your View Controller:
import FilterCamFilterCam is a drop-in convenience framework. To create a Camera instance, create a new UIViewController subclass. Replace the UIViewController subclass declaration with FilterCamViewController:
class MyCameraViewController : FilterCamViewControllerThat is all that is required to setup the AVSession for photo and video capture. FilterCam will prompt the user for permission to use the camera/microphone, and configure both the device inputs and outputs.
Capturing Video is just as easy. To begin recording video, call the startRecording function:
startRecording()To end the capture of a video, call the stopRecording function:
stopRecording()You must implement the FilterCamViewControllerDelegate and set the cameraDelegate to your view controller instance:
class MyCameraViewController : FilterCamViewController, FilterCamViewControllerDelegate {
override func viewDidLoad() {
super.viewDidLoad()
cameraDelegate = self
}
...
}func filterCamDidStartRecording(_ filterCam: FilterCamViewController) {
// Called when startRecording() is called
}
func filterCamDidFinishRecording(_ filterCame: FilterCamViewController) {
// Called when stopRecording() is called
}
func filterCam(_ filterCam: FilterCamViewController, didFinishWriting outputURL: URL) {
// Called when stopRecording() is called and the video is finished processing
// Returns a URL in the temporary directory where video is stored
}
func filterCam(_ filterCam: FilterCamViewController, didFocusAtPoint tapPoint: CGPoint) {
// Called when a user initiates a tap gesture on the preview layer
// Returns a CGPoint of the tap location on the preview layer
}
func filterCam(_ filterCam: FilterCamViewController, didFailToRecord error: Error) {
// Called when recorder fail to record
}The torch can be enabled by changing the torchLevel property:
torchLevel = 1Torch level specifies the value between 0.0 and 1.0.
By default, FilterCam will launch to the rear facing camera. This can be changed by changing the defaultCamera property in viewDidLoad:
devicePosition = .frontYou can apply custom filters by specifying an array of filters in the filters property:
filters = [CIFilter(name: "CIPhotoEffectInstant")!, CIFilter(name: "CIPhotoEffectNoir")!]filters property type is an array of CIFilter. It is applied sequentially from the first filter.
If you want to specify the preview frame, you can use custom initializer:
MyCameraViewController(previewViewRect: CGRect)Video quality can be set by the videoQuality property of FilterCamViewController. The choices available AVCaptureSessionPreset.
