How has code signing changed in the migration?

Key properties have been renamed; for example, 'CodeSigningKey' must be changed to 'CodesignKey' or it will be silently ignored by the new build system.

What is the recommended way to migrate the project file?

The strategy recommended by this skill is to create a new .NET for iOS project and copy your code into it, rather than attempting to manually edit the legacy project file.

Why are my existing iOS NuGet packages not working?

Unlike Android, Apple-platform Xamarin packages (monotouch, xamarinios) are not backward compatible with .NET TFMs and must be recompiled for net8.0-ios.

Can I use this for Xamarin.Forms applications?

No, this skill is specifically designed for native Xamarin.iOS, macOS, and tvOS projects. For Xamarin.Forms, use the xamarin-forms-migration skill.

Does .NET support watchOS migration from Xamarin?

No, Xamarin.watchOS has no .NET equivalent. This skill provides guidance on bundling Swift extensions with .NET for iOS apps as an alternative.

Mobile Development

Guides the migration of legacy Xamarin.iOS, macOS, and tvOS applications to modern .NET SDK-style projects.

This skill provides a structured workflow and technical reference for upgrading Xamarin native Apple platform projects to .NET 8 and beyond. It assists developers in converting project files to the modern SDK style, mapping MSBuild properties, resolving NuGet incompatibilities—specifically addressing the lack of backward compatibility for iOS packages—and correctly configuring code signing. It is an essential tool for developers transitioning legacy Apple-platform codebases to the unified .NET ecosystem while avoiding common pitfalls like silent signing failures and unsupported frameworks.
