SwiftUI changes in Xcode 11 Beta 3

Today release of Xcode 11 Beta 3 brings some change to SwiftUI components. I will highlight some obvious one, you can check the rest here.

NavigationButton -> NavigationLink #

NavigationView {

List {

Text ( "Hello World" )

NavigationLink ( destination : Text ( "Detail" ) ) {

Text ( "Detail" )

}

}

. navigationBarTitle ( Text ( "Navigation Title" ) )

}

Reference

PresentationButton -> PresentationLink #

PresentationLink ( destination : Text ( "Present" ) , label : { Text ( "Popup" ) } )

Reference

We can finally use SF Symbol here and we can init .tabItem with Image and Text directly without VStack .

TabbedView {

Text ( "First" )

. font ( . title )

. tabItem { Text ( "First" ) }

. tag ( 0 )

Text ( "Second" )

. font ( . title )

. tabItem {

Image ( systemName : "circle" )

Text ( "Second" )

}

. tag ( 1 )

}

Reference

New initializer for most views with label #

Most SwiftUI views got a initializer accepting @ViewBuilder as a label which quite verbose for most case where we just need simple Text .

In this beta 3 those views get a new initializer which accept LocalizedStringKey .

Instead of.

Button ( action : {

print ( "Button tapped" )

} ) {

Text ( "Button" )

}

We can shorten it with.

Button ( "Button" ) {

print ( "Button tapped" )

}
