I’m trying to make my iPhone apps (targeting iOS 15 and above) fully compatible with iOS 16 without success!
I don’t know how to have NavigationView
for iOS 15 and NavigationStack
for iOS 16 in the same piece of code.
The code above isn’t accepted by Xcode:
if #available(iOS 16, *) {
NavigationStack {
} else {
NavigationView {
}
From: SwiftUI NavigationView/Stack if available iOS 15/16
I guess that creating a custom container, as suggested by @timmy, will be the only solution. But I don’t know how to proceed.
What’s the solution then?

Personally I wouldn’t use
NavigationStack
unless I would target iOS 16+ but if you want to do that you could make your own Navigation Wrapperand then just use it, like you would
NavigationStack
orNavigationView
and on iOS 15 or older it would useNavigationView
and on iOS 16 or newer it would useNavigationStack
Your code isn’t accepted by Xcode because it isn’t valid. You cannot have a
{
without a}
in the same block.I have found that using
NavigationView
can present problems on both iPhone and iPad apps running under iOS 16, even thoughNavigationView
is only deprecated for now. On an iPhone, views reached from aNavigationLink
often close themselves as soon as they are opened. On an iPad, the same problem occurs and the generation of Back arrows appears to be a bit random, especially in document apps. I have found it well worth making the effort to useNavigationSplitView
andNavigationStack
, even though this has involved me writing quite a lot of extra code to achieve pleasing results, particularly in apps designed to run at their best on both iPhone and iPad. That said, Apple do provide some clear advice on how to adopt the new Views here.I have come across another oddity with iOS 16. Pickers in modal sheets, which have their list arrays populated
.onAppear
, no longer work as intended and the Picker selection can no longer be set programmatically. You have to populate the Picker’s list before activating the modal sheet and pass it to the Sheet as aBinding
.Thanks halo for a top tip on how to use
if #available()
