Update iOS SDK to 17 or later

Question

Update iOS SDK to 17 or later

Huynh Than 65

Hi, After publishing my app to AppStore, I received this email

User's image

I'm using Visual Studio 2022 Mac version 17.6.9 (build 415) , and Xcode 15.2

After receiving that email, I went to my iOS Xamarin project -> Properties -> iOS->Build and changed my SDK version from "default" to "17.2". However, when I attempted to release a new version via Transferer which is the tool I used to make the build available in the Apple Developer portal, I received the warning message email again.

There is a post about this problem although it is a Flutter-related thing.

https://github.com/FlutterFlow/flutterflow-issues/issues/2334

Any suggestion how to fix this issue?

From the screenshot, it's a warning and it shows that you are using iOS16.2 SDK. The latest Xamarin.iOS version is 16.4. (And it allows Xcode15.2 tool builds). Please try updating Xamarin.iOS. Also, If you don't use new APIs, you could try to approve your app to Apple.

In addition, Xamarin support will end on May 1, 2024 for all Xamarin SDKs including Xamarin.Forms. Android API 34 and Xcode 15 SDKs (iOS and iPadOS 17, macOS 14) will be the final versions Xamarin will target from existing Xamarin SDKs (i.e. no new APIs are planned). See Xamarin Support Policy.

And you could upgrade Xamarin projects to .NET, see the Upgrade from Xamarin to .NET & .NET MAUI documentation.

I'm a bit confused. What do you mean by updating Xamarin.iOS? Is it the same thing as migrating my Xamarin App to .NET MAUI?

No, they are not same. For updating Xamarin.iOS: Open VS for Mc-> click Visual Studio in the top menu bar->Check for Updates

(From the warning you provided, you are using Xamarin.iOS 16.2 SDK, and you can update to 16.4)

Also, if you don't use the new API, you can ignore the warning and submit the app for review.

Answer 1

visual studio Mac with lastest updates, and lastest packages in your project should be IOS 17. going forward you need a migration path. Xamarin.macios is still supported and used by Maui. But you need a tool to sign the code. There are open feature requests for a visual studio code signing tool, but no commitment. You can install parallels and use visual studio windows to sign after converting to Maui project type. while not well documented, you can still use storyboard with Maui projects.https://learn.microsoft.com/en-us/dotnet/maui/migration/apple-projects?view=net-maui-8.0

you can also use Jetbrains Rider. it generates a Xcode project binding, so you can use Xcode to sign.
