### Environment

- OS: MacOS Sequoia 15.5
- .NET MAUI: 9.0.100
- Target platforms: iOS 18.1

Commencez par le groupe de propriétés de `MaulSample.csproj` et la reproduction `newBinding.sln` sous `template/sample` ; exécutez `dotnet publish -f net9.0-ios -c Release` et examinez le rapport d’erreur joint. Le travail est terminé lorsque l’IPA résultante se déploie sur un appareil iOS physique et se lance sans le crash signalé lié à un symbole manquant.
