Error: The version of the Package.resolved is not supported

[JulesMoorhouse]

I'm using Xcode 15.3 and the build phase for swift-package-list creates this error

Error: The version of the Package.resolved is not supported

I have the following

.package(url: "https://github.com/FelixHerrmann/swift-package-list.git", from: "4.1.0"),
.product(name: "SwiftPackageListUI", package: "swift-package-list"),

Earlier I had the old version 3.0.10, which had the same issue, upgrading didn't help.

Any suggestions please ?

Thanks,

Jules

Xcode 15.3 introduces the 3rd version of the Package.resolved format. 3.1.0 added support for that in #73 and also changed the error message to indicate the (unsupported) version it received. Your error indicates that you still use 3.0.10 so please make sure you have it correctly installed. You can also give the SPM plugin a shot instead of the manual run script phase, this eliminates any local installation issue automatically, see #build-tool-plugin. Let me know if that helped!

Hmmm, I'm a bit confused as to whats going on.

I reverted back to Xcode 15.2 after I posted earlier and things seemed to be working. However, I didn't go into to acknowledgements screen to see what was being shown.

Before I posted the issue above, I was using Xcode 15.3, and was seeing swift-package-list 4.1.0 in my pacakges, and was getting the error I posted. So what you say confuses me.

Now, I've switched back to 15.3, I'm no longer getting the error, which puzzles me. I haven't added the build-tool-plugin to my spm, where I'm using swift-package-list, as I'm a bit confused about what I should add to my package file. I know you have a link the swift forums, but I'm not sure what to add.

Anyways, here's my build phase scripting... which was working previously.

if test -d "/opt/homebrew/bin/"; then
  PATH="/opt/homebrew/bin/:${PATH}"
fi

export PATH

if command -v swift-package-list &> /dev/null; then
    OUTPUT_PATH=$SOURCE_ROOT/$TARGETNAME
    #swift-package-list $PROJECT_FILE_PATH --output-path "$OUTPUT_PATH" --requires-license --file-type plist
    #mv "$OUTPUT_PATH/package-list.plist" "$OUTPUT_PATH/../Acknowledgements.plist"
    swift-package-list generate "$PROJECT_FILE_PATH" --output-path "$OUTPUT_PATH" --requires-license --file-type plist
else
    echo "warning: swift-package-list not installed, https://github.com/FelixHerrmann/swift-package-list"
    echo "use brew tap FelixHerrmann/tap"
    echo "use brew install swift-package-list"
fi

I've created the file... swift-package-list-config.json

{
    "projectPath" : "myapp.xcworkspace",
    "project" : {
        "outputType" : "plist",
        "requiresLicense" : false
    },
    "targets" : {
        "myapp" : {
            "outputType" : "plist",
            "requiresLicense" : true
        }
    }
}

I can also see that my package-list.plist is being updated, but not being changed, git isn't picking up changes, but the file is being modified.

Also, I can't see any of the licenses in my acknowledgements screen.

But I don't have a build error.

As I say I'm a bit confused.

Edit: Now, I've switched back to 15.3, I'm no longer getting the error, which puzzles me. -> Because I have 4.10

It could be the case Xcode 15.2 reverted the Package.resolved format back to v2 and after going to 15.3 it remained like that (I think it only gets upgraded when you trigger an SPM update). Anyways let me clarify the 2 main options you have for you project so you don't mix up things that shouldn't be:

Homebrew installation + Run Script

• install and update the swift-package-list tool on your machine, e.g. via Homebrew
• set up the Run Script Phase which invokes this tool
• on new projects you have to disable the User Script Sandboxing build setting
• the file will be generated into your project's directory and needs to be manually added to the project and target
• optionally add the SwiftPackageList package to your project to interact with the generated file conveniently

SPM Plugin

• add the SwiftPackageList package to your project
• in your target's build settings add the SwiftPackageListPlugin to the Run Build Tool Plug-ins
• if you don't want to use the JSON output format or you have a workspace you can create an optional swift-package-list-config.json in your project's root to configure the plugin
• the files will get generated into a directory in Derived Data and loaded into the bundle as part of the build process (all managed by Xcode)
• interact with the files on runtime as you are used to

I haven't added the build-tool-plugin to my spm, where I'm using swift-package-list, as I'm a bit confused about what I should add to my package file. I know you have a link the swift forums, but I'm not sure what to add.

If you have a normal Xcode project (or workspace) you have to add the plugins via UI:

Thanks for your help. I've got everything working.

There were some changes I wasn't aware of, which weren't immediately apparent.

AcknowledgmentsList(packageProvider: .propertyList())

Also more obvious file-type to output-type.
