Swift Package Manager

The Swift Package Manager is a tool for automating the distribution of Swift code and is integrated into the swift compiler. It is in early development, but Alamofire does support its use on supported platforms.

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

dependencies: [
  .package(url: "https://github.com/Kofktu/PIPKit.git", .upToNextMajor(from: "1.0.0"))
]

Usage

PIPUsable

public protocol PIPUsable {
    var initialState: PIPState { get }
    var initialPosition: PIPPosition { get }
    var insetsPIPFromSafeArea: Bool { get }
    var pipEdgeInsets: UIEdgeInsets { get }
    var pipSize: CGSize { get }
    var pipShadow: PIPShadow? { get }
    var pipCorner: PIPCorner? { get }
    func didChangedState(_ state: PIPState)
    func didChangePosition(_ position: PIPPosition)
}

PIPKit

class PIPKit {
    var isPIP: Bool
    var isActive: Bool
    var visibleViewController: PIPKitViewController?

    class func show(with viewController: PIPKitViewController, completion: (() -> Void)? = nil)
    class func dismiss(animated: Bool, completion: (() -> Void)? = nil)
}

PIPKitViewController (UIViewController & PIPUsable)

func setNeedsUpdatePIPFrame()
func startPIPMode()
func stopPIPMode()

At a Glance

Show & Dismiss

class PIPViewController: UIViewController, PIPUsable {}

let viewController = PIPViewController()
PIPKit.show(with: viewController)
PIPKit.dismiss(animated: true)

Update PIPSize

class PIPViewController: UIViewController, PIPUsable {
    func updatePIPSize() {
        pipSize = CGSize()
        pipEdgeInsets = UIEdgeInsets()
        setNeedsUpdatePIPFrame()
    }
}

FullScreen <-> PIP Mode

class PIPViewController: UIViewController, PIPUsable {
    func fullScreenAndPIPMode() {
        if PIPKit.isPIP {
            stopPIPMode()    
        } else {
            startPIPMode()
        }
    }

    func didChangedState(_ state: PIPState) {}
}

AVPIPKitUsable

UIView that is capable of Picture-in-Picture in iOS (AVKit.framework)

Requirements

• iOS 15 or higher
• Info.plist - Audio, AirPlay and Picture in Picture in Background Modes. For more information, see Apple Documentation

var PIPKit.isAVPIPKitSupported: Bool

AVPIPKitRenderer

protocol AVPIPKitRenderer {
    
    var policy: AVPIPKitRenderPolicy { get }
    var renderPublisher: AnyPublisher<UIImage, Never> { get }
    
    func start()
    func stop()
    
}

AVPIPUIKitUsable

class View: UIView, AVPIPUIKitUsable {

    var pipTargetView: UIView { self } // Return the subview that you want to show.
    var renderPolicy: AVPIPKitRenderPolicy {
        // .once - only once render
        // .preferredFramesPerSecond - render in frames-per-second
    }
}

view.startPictureInPicture()
view.stopPictureInPicture()

class ViewController: UIViewController, AVPIPUIKitUsable {
    var pipTargetView: UIView { view } // Return the subview that you want to show.

    func start() {
        startPictureInPicture()
    }

    func stop() {
        stopPictureInPicture()
    }
}
