Question Regarding Swift Package Resolution on 1.18.0

[rig-0]

I'm encountering the following error when attempting to update to 1.18.0 and I'm not yet clear on whether this is an issue caused by 1.18.0 or whether this is a user error:

multiple similar targets 'IssueReporting', 'IssueReportingTestSupport', 'XCTestDynamicOverlay' appear in package 'swift-issue-reporting' and 'xctest-dynamic-overlay', this may indicate that the two packages are the same and can be de-duplicated by using mirrors. if they are not duplicate consider using the moduleAliases parameter in manifest to provide unique names

We have a rather complex project setup with many swift packages (many of which are self-managed dependencies), and so my workflow to resolve packages is the following:

1. From root directory, call swift package update in terminal. This updates the root-level Package.resolved file.
2. I copy this resolved file into /zzz.xcodeproj/project.xcworkspace/xcshareddata/swiftpm/Package.resolved.

It's only after the second stop (copying over the resolved file) that Xcode throws the error. If I only update the root level resolved file, everything is fine.

Do you have any thoughts about how I can resolve this? In the meantime, I am staying on 1.17.7. Thanks for your help, and please let me know if you need any more information about my setup.

@rig-0 Are you depending on swift-issue-reporting directly? Can you share your package file?

So, I hope this is enough information to go off, but yes, in a way, we are depending on swift-issue-reporting directly, through an internally managed package.

The top section is a preview of our main app's swift package. It has a reference to our internally managed foundation package, as well as snapshot testing. The following section is a preview of our foundation package, which has dependencies on swift-issue-reporting as well as a the swift-tagged package.

name: "ZZZApp",
dependencies: [
	.package(url: "https://github.com/ZZZ/zzz-foundation", exact: .init(1, 0, 0)),
	.package(url: "https://github.com/pointfreeco/swift-snapshot-testing", from: .init(1, 14, 2)),
],
targets: [
	...
	.testTarget(
		name: "SnapshotTests",
		dependencies: [
			...
			.product(name: "SnapshotTesting", package: "swift-snapshot-testing", condition: .when(platforms: [.tvOS])),
		]
	),
]

name: "ZZZFoundation",
dependencies: [
	...
	.package(url: "https://github.com/pointfreeco/swift-issue-reporting", from: .init(1, 4, 0)),
],
targets: [
	...
	.target(
		name: "ZZZTarget",
		dependencies: [
			...
			.product(name: "IssueReporting", package: "swift-issue-reporting"),
		]
	),
]

I have a similar setup like @rig-0 and have the same issue. I also had this in the past. Have to revert the upste because of that!

I thought we had this documented, but currently you should not be depending on pointfreeco/swift-issue-reporting. You should be depending on: http://github.com/pointfreeco/xctest-dynamic-overlay

I know that is confusing, but unfortunately doesn't support redirects for repo renames, and so this is necessary until we can fully rename and archive the old repo.

Ok sorry I missed the docs on that will change the dependency. This indeed solved my issue. Thanks @mbrandonw and @stephencelis for the quick response and awesome package!
