Wyler

Wyler is a lightweight Swift library that simplifies screen recording on iOS. You can record your app screen, access the recorded video file, and optionally save it to the Photo Library.

Features

• App screen recording with ReplayKit
• Optional microphone and app audio capture
• Configurable output URL and video size
• Optional save to the Photo Library
• CocoaPods, Carthage, Swift Package Manager, or manual integration

Requirements

• iOS 11.0+
• Swift 5.9+

Installation

Since Wyler is implemented in a single source file, the simplest setup is to drag ScreenRecorder.swift into your Xcode project. If you prefer a package manager:

Swift Package Manager

Add Wyler to your package dependencies:

.package(url: "https://github.com/toupper/Wyler.git", from: "1.0.1")

CocoaPods

platform :ios, '11.0'
use_frameworks!

target 'MyApp' do
  pod 'Wyler', '~> 1.0'
end

Carthage

github "toupper/Wyler" ~> 1.0

Usage

Import Wyler where you want to start recording:

import Wyler

let screenRecorder = ScreenRecorder()

Start a recording with the default output URL:

screenRecorder.startRecording(saveToCameraRoll: true) { error in
    debugPrint("Error when recording: \(error)")
}

Customize the output URL, size, and audio capture:

screenRecorder.startRecording(
    to: yourInternalURL,
    size: yourSize,
    saveToCameraRoll: true,
    recordAudio: shouldRecordAudio
) { error in
    debugPrint("Error when recording: \(error)")
}

Stop recording:

screenRecorder.stopRecording { error in
    debugPrint("Error when stopping recording: \(String(describing: error))")
}

If you save to the Photo Library, add NSPhotoLibraryAddUsageDescription to your app's Info.plist.

Notes

• Wyler uses ReplayKit, so recording availability depends on Apple platform restrictions.
• Saving to the Photo Library is skipped unless saveToCameraRoll is true.
