SPFKMetadata wraps TagLib (v2.0.2), libsndfile (v1.2.2) and Core Audio metadata C/C++ frameworks for Swift compatibility. This library is currently macOS only, though will updated to include iOS soon.
The current state of metadata parsing via Swift means that no one single framework is a do-it-all solution, so this framework covers some missing functionalities from AVFoundation such as RIFF Audio Markers, Chaptering, Broadcast Wave and writing tags to file. SPFKMetadata embeds arm64/x86_64 xcframeworks for the needed dylibs and uses an intuitive Swift API to access metadata functions from each. While Apple's C++ → Swift interoperability looks promising, it doesn't yet seem ready for integration in which you don't control both sides of the integration. For this reason, open source frameworks like TagLib and libsndfile seem better bridged via Objective C++. I'm sure this will eventually change as Swift moves closer to C++ interoperability.
There are two targets in the package: SPFKMetadata and SPFKMetadataC. The first is pure Swift whereas the second is C++ bridged by Objective C++. For full functionality both imports are required.
- Add SPFKMetadata as a dependency in the usual ways.
- In a project or framework, in Xcode:
- Select the menu: File → Swift Packages → Add Package Dependency...
- Enter this URL:
https://github.com/ryanfrancesconi/SPFKMetadata
- In a Swift Package, add it to the Package.swift dependencies:
.package(url: "https://github.com/ryanfrancesconi/SPFKMetadata", branch: "main")
- In a project or framework, in Xcode:
- Import the libraries:
import SPFKMetadata import SPFKMetadataC
