.NET MAUI iOS – Azure Pipelines error: ‘x’ is not available in iOS 16
This content has 9 months. Some of the information in this post may be out of date or no longer work.

This discrepancy indicates a version misalignment in the development environment, specifically with the iOS SDK and Xcode. Root cause The root cause of this error lies in the version of the macOS image used in the Azure Pipelines configuration. By default, the ‘macOS-latest’ image is pulled, which corresponds to macOS 12 (at the time of the blog post).

Step-by-Step -Open your Azure Pipelines configuration file (typically named azure-pipelines.yml).-Locate the section where the macOS image is specified. It might look something like this: -Update the image reference to ‘macOS-13’: -Save the changes to the configuration file.-Commit the updated configuration file to your version control system (e.g., Git).-Trigger a new build in Azure Pipelines,…
