Photo picking in SwiftUI uses the `PhotosPicker` view to enable seamless image and video selection from a user's library. You configure it for single or multiple selections, then asynchronously load and display the returned image data.

Managing media permissions requires explicitly requesting photo library and camera access before capture or selection. You must add specific usage description strings to your Info.plist and handle all permission states gracefully to ensure a smooth user experience.

Camera capture and video recording use `AVCaptureSession` to coordinate data flow from device inputs to file outputs. You configure session inputs, add photo or video outputs, and display a preview layer to enable real-time media recording within your Swift application.

Efficient image loading requires downsampling large photo assets during the data loading process. By configuring loading options to request a specific target size, you reduce memory overhead and ensure images display smoothly without exceeding application memory limits.

You can build a profile picture feature in SwiftUI by combining `PhotosPicker` for library selection and `AVCaptureSession` for camera capture. This approach handles both selecting existing photos and taking new ones while managing the necessary privacy permissions and loading states.
