struct GenerativeView: View {
private var model = SystemLanguageModel.default
var body: some View {
switch model.availability {
case .available:
ContentView()
case .unavailable(.deviceNotEligible):
Text("设备不符合 Apple Intelligence 的使用条件")
case .unavailable(.appleIntelligenceNotEnabled):
Text("请在设置中启用 Apple Intelligence")
case .unavailable(.modelNotReady):
Text("模型正在下载或尚未就绪")
case .unavailable(let other):
Text("模型不可用：\(other)")
}
}
}
