Starting from iOS 11, Apple introduces a new framework called Vision.
The Vision framework performs face and face landmark detection, text detection, barcode recognition, image registration, and general feature tracking. Vision also allows the use of custom Core ML models for tasks like classification or object detection.
Today I want to show you how to use the Apple ReplayKit, to record a full-screen video without a status-bar from your app and save it in your library without using external libraries like GPUImages or something like that.
With the NetworkExtension framework, you can customize and extend the core networking features of iOS and macOS. Specifically, you can:
Change the system’s Wi-Fi configuration
Integrate your app with the hotspot network subsystem (Hotspot Helper)
Create and manage VPN configurations, using the built-in VPN protocols (Personal VPN) or a custom VPN protocol
Implement an on-device content filter
Implement an on-device DNS proxy
The NetworkExtension framework is available in macOS and iOS, but not all features are available on both platforms and some features have specific restrictions (for example, some features only work on supervised iOS devices). The documentation for each feature describes these restrictions.
