Hi,

I recently updated Xcode to latest version - 27. However, the current .NET iOS workload does not appear to support this version yet. While building my project, I received the following error -

"This version of .NET for iOS (26.5.10318) requires Xcode 26.6. The current version of Xcode is 27.0. Either install Xcode 26.6, or use a different version of .NET for iOS."

I would like to know:

  • Is there an expected timeline for when .NET iOS will support Xcode 27?

For context:

  • .NET SDK version: 10.0.401
  • iOS workload: 26.5.10318
  • Development environment: Rider on macOS

Any guidance or updates would be appreciated.

Thank you.

Each release of the Maui build tools are tied to a version of Xcode. You will need to wait for another release of Maui to get Xcode 27. In the mean time you need to reinstall Xcode 26 (Google for instructions for side by side if you want). Probably the Maui 11 release next month will support Xcode 27 and the iOS 27 sdk.
