Generate a list of license information for all Swift packages used in your project. For easy *Acknowledgement* views.

Full Changelog: 0.1.4...0.1.6


Simple Acknowledgements Generator for SPM package license information.


AckGen automatically generates a plist file containing the title and license information for all Swift packages used in your project.
This can be used to feed a SwiftUI List or UITableView dataSource in your app.


  • Xcode 12+ (tested with 12.5)


  1. Add AckGen as a dependency for your project in Xcode.

Warning Leave the checkbox for executable unchecked

  1. Add the following as a Run Script for your target in Xcode
if [ -d "$DIR" ]; then
  cd $DIR
  SDKROOT=(xcrun --sdk macosx --show-sdk-path)
  swift run ackgen
  echo "warning: AckGen not found. Please install the package via SPM ("

If you want the plist file to be saved somewhere other than Acknowledgements.plist at the root of your project ($SRCROOT/Acknowledgements.plist), you can provide a custom path as the first command line argument to ackgen above.

  swift run ackgen $SRCROOT/PackageLicenses.plist
  1. Add the generated plist file to your project if you haven't already.
    Make sure to remove the check for Copy items if needed

  2. You can now simply use the plist file however you like or use the Acknowledgement model for convenience:

import AckGen
// ...
let acknowledgements: [Acknowledgement] = Acknowledgement.all()
acknowledgements.forEach { print($0.title, $0.license) }


Optionally, there's a basic SwiftUI AcknowledgementsList component (see gif above) included in the AckGenUI module that you can use to quickly create a generic list of acknowledgements to embed into a NavigationView.

import AckGenUI
import SwiftUI

struct ContentView: View {
    var body: some View {
        NavigationView {


Until 1.0 is reached, minor versions will be breaking.


This is my first stab at building a Swift package and was mainly intended to be an exercise.
I hope, however, that it can be useful to someone other than me.

If you encounter any problems or have suggestions, additions or possible improvements to share, you are more than welcome to open a PR or issue and I'll get back to you as soon as my time allows it.
