🐞 Segfault when using asset catalog colors

Comienza con ContentView.swift en el EditorThemeReproduction.zip enlazado y reproduce el segfault al iniciar usando los valores de NSColor del catálogo de assets, especialmente NSColor.editorBackground. Compara la construcción fallida de EditorTheme con el caso funcional usingColorSpace(.sRGB). Se considera terminado cuando los colores del catálogo de assets pueden definir un EditorTheme sin una conversión explícita del espacio de color y la aplicación de reproducción se inicia sin un segfault.

Description

When creating an EditorTheme from asset catalog colours, a segfault occurs at launch unless the background colour is explicitly cast to sRGB (NSColor.editorBackground.usingColorSpace(.sRGB)!).

To Reproduce

1. Create a new SwiftUI macOS app
2. Add CodeEditSourceEditor as a dependency
3. Add sRGB colors sets to the Asset catalog
4. Use those colors through NSColor to define an EditorTheme (e.g. NSColor.editorBackground)
5. Launch the app
6. Something segfaults
7. If you set the background to NSColor.editorBackground.usingColorSpace(.sRGB)!, it doesn't

Expected Behavior

It should be possible to use colours from the asset catalog to define the theme colours without additional hijinks.

Version Information

CodeEditSourceEditor: 0.15.2
macOS: 15.7.4
Xcode: 26.3

Additional Context

Minimal reproduction project: EditorThemeReproduction.zip (ContentView.swift contains all the relevant code.)

How I'm creating the theme (the asset catalog is included with the above project):

extension EditorTheme {
    /// Creates an ``EditorTheme`` from colors defined in the asset catalog.
    static func fromAssetCatalog() -> Self {
        EditorTheme(
            text: EditorTheme.Attribute(color: NSColor.editorText),
            insertionPoint: NSColor.editorInsertionPoint,
            invisibles: EditorTheme.Attribute(color: NSColor.editorInvisibles),

            // This segfaults:
            background: NSColor.editorBackground,

            // This does not, despite the asset catalog color sets being defined as sRGB
            // background: NSColor.editorBackground.usingColorSpace(.sRGB)!,

            lineHighlight: NSColor.editorLineHighlight,
            selection: NSColor.editorSelection,
            keywords: EditorTheme.Attribute(
                color: NSColor.editorKeywords,
                bold: true
            ),
            commands: EditorTheme.Attribute(color: NSColor.editorCommands),
            types: EditorTheme.Attribute(color: NSColor.editorTypes),
            attributes: EditorTheme.Attribute(color: NSColor.editorAttributes),
            variables: EditorTheme.Attribute(color: NSColor.editorVariables),
            values: EditorTheme.Attribute(color: NSColor.editorValues),
            numbers: EditorTheme.Attribute(color: NSColor.editorNumbers),
            strings: EditorTheme.Attribute(color: NSColor.editorStrings),
            characters: EditorTheme.Attribute(color: NSColor.editorCharacters),
            comments: EditorTheme.Attribute(color: NSColor.editorComments)
        )
    }
}
