appName:"My App", selectedTab: selectedTab
){MyFirstTab()MySecondTab()MyThirdTab()} defaultContent:{MyDefaultContentView()} defaultDetail:{MyDefaultDetailView()} sidebarExtraContent:{Section{ForEach(folders){(folder)inFolderSidebarCell(folder)}}}.selectedTabTransformer(transformer)}}lettransformer=SelectedTabTransformer{(kind, tabIdentifier)inswitch kind {case.tabView:letsharedTabViewIdentifiers=[MyFirstTab.identifier,MySecondTab.identifier,MyThirdTab.identifier
]if !sharedTabViewIdentifiers.contains(tabIdentifier){returnMyFirstTab.identifier
}case.sidebarView:break}return tabIdentifier
}}

extensionMyFirstTab{staticletidentifier=TabIdentifier("MyFirstTab")}structMyFirstTab:View,TitleImageProviding{lettitle="My First Tab"letsystemImageName="1.square"letid=MyFirstTab.identifier
