​
Camera & Media

PrismCameraClient wraps AVFoundation’s capture pipeline into a clean, Sendable API. Capture photos and video without managing AVCaptureSession, delegates, or output configurations directly.

​
Permissions

Camera Permission
import PrismCapabilities

let permission = PrismCameraClient.permissionStatus
// .notDetermined, .restricted, .denied, .authorized

// Request access
let granted = try await PrismCameraClient.requestAccess()

​
Camera Positions

PositionDescription
.frontFront-facing (selfie) camera
.backRear-facing camera
.externalExternal camera (iPad, Mac)

​
Photo Capture

Capture a Photo
let camera = PrismCameraClient(position: .back)

try await camera.start()

let settings = PrismPhotoSettings(
    flashMode: .auto,
    isHDREnabled: true,
    quality: .high
)

let photo = try await camera.capturePhoto(settings: settings)
// photo.imageData contains the captured JPEG/HEIC data

await camera.stop()

​
Photo Quality Levels

QualityDescription
.lowSmallest file size, reduced resolution
.mediumBalanced quality and size
.highHigh-resolution output
.maximumFull sensor resolution

​
Flash Modes

ModeBehavior
.offFlash disabled
.onFlash always fires
.autoFlash fires when needed

​
Video Capture

Switch to video mode for recording:
Record Video
let camera = PrismCameraClient(
    position: .back,
    mode: .video
)

try await camera.start()

// Start recording
try await camera.startRecording()

// ... record for desired duration ...

// Stop and get the file URL
let videoURL = try await camera.stopRecording()
print("Video saved to: \(videoURL)")

await camera.stop()

​
Switching Cameras

Switch Camera
// Switch from back to front
try await camera.switchPosition(to: .front)
Always call camera.stop() when you’re done. The camera session holds hardware resources and will prevent other apps from accessing the camera.

​
Photo Picker

For selecting existing media from the photo library, use PrismPhotoPicker from PrismUI:
Photo Picker (PrismUI)
import PrismUI

PrismPhotoPicker(
    selection: $selectedImage,
    filter: .images
)
