How to use Tagged<Self, UUID> as id?

• Package.swift

// swift-tools-version: 6.2
// The swift-tools-version declares the minimum version of Swift required to build this package.

import PackageDescription

let package = Package(
    // ...
    dependencies: [
        // ...
        .package(url: "https://github.com/pointfreeco/sqlite-data",
                 .upToNextMajor(from: "1.3.0"),
                 traits: ["SQLiteDataTagged"]),
        .package(url: "https://github.com/pointfreeco/swift-structured-queries",
                 .upToNextMajor(from: "0.25.2"),
                 traits: ["StructuredQueriesTagged"]),
        .package(url: "https://github.com/pointfreeco/swift-tagged.git", from: "0.10.0"),
    ],
    targets: [
        .target(
            // ...
            dependencies: [
                // ...
                .product(name: "SQLiteData", package: "sqlite-data"),
                .product(name: "StructuredQueries", package: "swift-structured-queries"),
                .product(name: "Tagged", package: "swift-tagged"),
                .product(name: "Dependencies", package: "swift-dependencies"),
            ]
        ),
        // ...
    ]
)

• MyModel.swift

import Foundation
import SQLiteData
import Tagged

@Table
public struct MyModel: Hashable, Identifiable {    
    public typealias ID = Tagged<Self, UUID>

    // Cannot convert value of type 'Tagged<MyModel, UUID.UppercasedRepresentation>.Type' 
    // to expected argument type 'any QueryRepresentable.Type'
    @Column(as: Tagged<Self, UUID.UppercasedRepresentation>.self)
    public let id: ID
}

It looks like UUID.UppercasedRepresentation and Tagged have already provided implementations of QueryRepresentable in StructuredQueries, but I don't know why the compiler complains.

I found the solution myself:

...
        .target(
            // ...
            dependencies: [
                // ...
                .product(name: "Tagged", package: "swift-tagged"),
                // This package is not really needed
                // .product(name: "StructuredQueries", package: "swift-structured-queries"), 
                .product(name: "Dependencies", package: "swift-dependencies"),
                .product(name: "SQLiteData", package: "sqlite-data"),
            ],

The key is to adjust the order of dependencies, placing the basic packages at the front.

The order of dependencies specified in the Package.swift should not actually matter. Perhaps your project was just in a bad state previously?

This is indeed possible. Since I upgraded to Xcode 26.1, SwiftPM has been having issues.
