Aperture
Swift library for high‑fidelity macOS screen and audio capture
A native Swift API that records macOS screens, windows, audio, or connected iOS devices with configurable video codecs, frame rates, and audio options.
Overview
Highlights
Record full screen, specific window, or custom region
Capture system audio, microphone, or both with lossless ALAC option
Choose from H.264, HEVC, ProRes 422, and ProRes 4444 codecs
Support for external iOS device capture
Pros
- Native Swift implementation leverages AVFoundation for performance
- Fine‑grained control over video and audio parameters
- Simple async API integrates with modern Swift concurrency
- Supports macOS 13+ and recent hardware
Considerations
- Limited to macOS; no Windows or Linux support
- Requires Xcode 15+ and Swift 5.7+
- Click‑highlighting only available on macOS 15+
- No built‑in UI; developers must create their own interface

Fit guide
Great for
- Developers building macOS utilities that need screen capture
- Automation scripts that generate screencasts programmatically
- Testing frameworks that record UI interactions
- Apps that bundle video tutorials or demos
Not ideal when
- Cross‑platform projects requiring Windows or Linux recording
- Users needing a ready‑made graphical recorder
- Environments without Xcode or Swift toolchain
- Real‑time streaming where ultra‑low latency is critical
How teams use it
Automated tutorial generation
Create high‑quality video guides directly from code without manual recording.
UI test documentation
Record test runs to review UI behavior and debug failures.
Live demo capture for product releases
Capture screen and system audio in a single step for marketing videos.
iOS device screen mirroring
Record the display of a connected iPhone or iPad for app demos.
