SwiftPackageList

A command-line tool to get all used SPM-dependencies of an Xcode project or workspace.

The output includes all the Package.resolved informations and the license from the checkouts. You can also generate a JSON, PLIST, Settings.bundle or PDF file.

Additionally there is a Swift Package to read the generated package-list file from the application's bundle with a top-level function or pre-build UI.

Command-Line Tool

Installation

Using Homebrew

brew tap FelixHerrmann/tap
brew install swift-package-list

Using Mint:

mint install FelixHerrmann/swift-package-list

Installing from source:

Clone or download this repository and run make install, make update or make uninstall.

Usage

Scan Command

Open the terminal and run swift-package-list scan <project-path> with the path to the .xcodeproj or .xcworkspace file you want to get the JSON output from.

In addition to that you can specify the following options:

Option	Description
-d, --derived-data-path <derived-data-path>	The path to your DerivedData-folder. (default: ~/Library/Developer/Xcode/DerivedData)
-s, --source-packages-path <source-packages-path>	The path to a custom SourcePackages-folder.
--requires-license	Will skip the packages without a license-file.
--version	Show the version.
-h, --help	Show help information.

Generate Command

Open the terminal and run swift-package-list generate <project-path> with the path to the .xcodeproj or .xcworkspace file you want to generate the list from.

In addition to that you can specify the following options:

Option	Description
-d, --derived-data-path <derived-data-path>	The path to your DerivedData-folder. (default: ~/Library/Developer/Xcode/DerivedData)
-s, --source-packages-path <source-packages-path>	The path to a custom SourcePackages-folder.
-o, --output-path <output-path>	The path where the package-list file will be stored. (default: ~/Desktop)
-f, --file-type <file-type>	The file type of the generated package-list file. Available options are json, plist, settings-bundle and pdf. (default: json)
-c, --custom-file-name <custom-file-name>	A custom filename to be used instead of the default ones.
--requires-license	Will skip the packages without a license-file.
--version	Show the version.
-h, --help	Show help information.

Build Tool Plugins

For each file type there is a dedicated plugin available which you can add to your targets.

Simply add them under the Run Build Tool Plug-ins section in the Target's Build Phases tab after you have added this package to the project's Package Dependencies.

Once added the file(s) will get generated during every build process and are available in the App's bundle. You can then open them manually or use the various options in the included Swift Package.

Note

When using Xcode Cloud add defaults write com.apple.dt.Xcode IDESkipPackagePluginFingerprintValidatation -bool YES to ci_post_clone.sh which disables the plugin validation.

Run Script Phase

You can easily set up a Run Script Phase in your target of your Xcode project to keep the package-list file up to date automatically:

1. open the corresponding target and click on the plus under the Build Phases section
2. select New Run Script Phase and add the following script into the code box:

if command -v swift-package-list &> /dev/null; then
    OUTPUT_PATH=$SOURCE_ROOT/$TARGETNAME
    swift-package-list generate "$PROJECT_FILE_PATH" --output-path "$OUTPUT_PATH" --requires-license
else
    echo "warning: swift-package-list not installed"
fi

3. move the Phase above the Copy Bundle Resources-phase
4. optionally you can rename the Phase by double-clicking on the title
5. build your project (cmd + b)
6. right-click on the targets-folder in the sidebar and select Add Files to "<project-name>"
7. select package-list.json in the Finder-window

The package-list file will be updated now on every build and can be opened from the bundle in your app. You can do that manually or use the Swift Package for that.

Xcode Workspace (CocoaPods)

If you have an Xcode workspace instead of a standard Xcode project everything works exactly the same, you just need a slightly modified script for the Run Script Phase:

if command -v swift-package-list &> /dev/null; then
    OUTPUT_PATH=$SOURCE_ROOT/$TARGETNAME
    WORKSPACE_FILE_PATH=${PROJECT_FILE_PATH%.xcodeproj}.xcworkspace
    swift-package-list generate "$WORKSPACE_FILE_PATH" --output-path "$OUTPUT_PATH" --requires-license
else
    echo "warning: swift-package-list not installed"
fi

Homebrew Troubleshooting on Apple Silicon

If you used Homebrew to install the Command-Line Tool on an Apple Silicon Mac, Xcode will not recognize the swift-package-list command. This is because Homebrew uses it's own /bin directory and Xcode's PATH environment variable is not aware of that. There are 2 easy ways to fix this issue:

• add export PATH="$PATH:/opt/homebrew/bin" as the first line to your build script
• execute ln -s /opt/homebrew/bin/swift-package-list /usr/local/bin/swift-package-list in your Terminal

Mint Troubleshooting

If you used Mint to install the Command-Line Tool, Xcode will not recognize the swift-package-list command. This is because Mint uses it's own /bin directory and Xcode's PATH environment variable is not aware of that. There are 2 easy ways to fix this issue:

• add export PATH="$PATH:$HOME/.mint/bin/" as the first line to your build script
• execute ln -s $HOME/.mint/bin/swift-package-list /usr/local/bin/swift-package-list in your Terminal

Settings Bundle

You can also generate a Settings.bundle file to show the acknowledgements in the Settings app. This works slightly different than the other file types, because a Settings Bundle is a collection of several files and might already exist in your app. Just specify --file-type settings-bundle on the command execution.

Important: The Root.plist and Root.strings files will (unlike the other files) only be created if they not already exists, otherwise it would remove existing configurations. Make sure you set up the Acknowledgements.plist correctly as a Child Pane as shown below:

<dict>
    <key>Type</key>
    <string>PSChildPaneSpecifier</string>
    <key>Title</key>
    <string>Acknowledgements</string>
    <key>File</key>
    <string>Acknowledgements</string>
</dict>

For more information on how to set up and use a Settings Bundle, take a look at Apple's documentation.

PDF

On macOS it is more common to show a Acknowledgments.pdf file. Therefore you have the option to generate a PDF with all licenses. Just specify --file-type pdf on the command execution.

It uses the project's file name (without extension) as the product name and, if present, the organization-name from the project file. You can set that in your project's file inspector as shown here.

Once created and added to the project, it can be easily accessed from the application's bundle like the following:

let url = Bundle.main.url(forResource: "Acknowledgements", withExtension: "pdf")

You can then use QuickLook, NSWorkspace.open(_:) or any other method to display the PDF.

Swift Package

Load package-list.json or package-list.plist from the bundle with a single function call or use the pre-build UI components.

Requirements

• macOS 10.10+
• iOS 9.0+
• tvOS 9.0+
• watchOS 2.0+

Usage

Add the package to your project as shown here.

It contains 3 libraries; SwiftPackageList/SwiftPackageListObjc for loading the Data in Swift and Objective-C and SwiftPackageListUI to get an iOS Settings-like user interface.

SwiftPackageList

import SwiftPackageList

do {
    let packages = try packageList()
    // use packages
} catch PackageListError.noPackageList {
    print("There is no package-list file")
} catch {
    print(error)
}

SwiftPackageListObjc

@import SwiftPackageListObjc;

NSError *error;
NSArray<SPLPackage *> *packages = SPLPackageList(&error);
if (packages) {
    // use packages
} else {
    if (error.code == SPLErrorNoPackageList) {
        NSLog(@"There is no package-list file");
    } else {
        NSLog(@"%@", error);
    }
}

SwiftPackageListUI

import SwiftPackageListUI

let acknowledgmentsViewController = SPLAcknowledgmentsTableViewController()
acknowledgmentsViewController.canOpenRepositoryLink = true
navigationController.pushViewController(acknowledgmentsViewController, animated: true)

import SwiftPackageListUI

var body: some View {
    NavigationView {
        AcknowledgmentsList()
    }
}
