🐞 Segfault when using asset catalog colors

Commencez par ContentView.swift dans l’archive EditorThemeReproduction.zip liée et reproduisez le segfault au lancement en utilisant les valeurs NSColor du catalogue d’assets, en particulier NSColor.editorBackground. Comparez la construction défaillante de EditorTheme avec le cas fonctionnel usingColorSpace(.sRGB). C’est terminé lorsque les couleurs du catalogue d’assets peuvent définir un EditorTheme sans conversion explicite de l’espace colorimétrique et que l’application de reproduction se lance sans 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)
        )
    }
}
