Compiler Directives

  • constants for Apple Platforms OS
 iOS , tvOS, macOS, watchOS, iPadOS (should be this for iPad)
  • directive model
 #if os(iOS) || os(tvOS)
     ...
 #elseif (os(macOS)
    ...
 #endif
  • In #if compiler directive in Swift, you need to enclosed valid statements.


You may need to write something like this: 

 #if os(iOS)
     var body: some View {
         NavigationView{
              ...
         }
         .navigationViewStyle(StackNavigationViewStyle())
     }
 #else
      var body: some View {
          NavigationView{
                ...
         }
        .navigationViewStyle(DoubleColumnNavigationViewStyle())
      }
 #endif

Or this: 

 var body: some View {
      let navView = NavigationView{
      ...
  }
  #if os(iOS)
      return navView
      .navigationViewStyle(StackNavigationViewStyle())
  #else
      return navView
      .navigationViewStyle(DoubleColumnNavigationViewStyle())
  #endif
  }

but not this: As you can see, .navigationViewStyle(StackNavigationViewStyle()) is not a valid statement. 

     NavigationView {
         ...
     }
 #if os(iOS)			
     .navigationViewStyle(StackNavigationViewStyle())
 #endif

  • mostly on a simulator to access a http://localhost:portnum/service hosted on the same host
  • IOS reinforce the access to HTTPS only since ioS 7
  • for sometime it was possible to grant htpp access in the info plist but now we have to grant more things
