GLTFQuickLook Modern App Extension

This folder contains the modern macOS App Extension implementation of GLTFQuickLook for macOS 10.15 (Catalina) and newer, including full support for Apple Silicon (M1/M2/M3) and upcoming macOS versions like Sequoia and Tahoe.

Apple deprecated .qlgenerator plugins and requires QuickLook extensions to be embedded inside a macOS application bag (.app).

Installation

1. Download the latest GLTFQuickLook.app release.
2. Drag and drop GLTFQuickLook.app into your /Applications folder.
3. Open the app once (it will launch and exit immediately, registering the QuickLook extensions with macOS).
4. Select any .gltf or .glb file in Finder and press Space to preview.

Build Setup

To build this modern extension from source, you need XcodeGen and macOS 12.0+ with Xcode.

# Install XcodeGen
brew install xcodegen

# Generate the Xcode Project
xcodegen

# Open the project
open GLTFQuickLook.xcodeproj

You can then build the GLTFQuickLook scheme directly from Xcode. Swift Package Manager will automatically fetch GLTFSceneKit.
