[BUG]: Add macOS 26.x (Tahoe) to the pool of MS-hosted agents #5507
Description
What happened?
We use Azure Pipelines to generate our mobile app builds as our company is a service provider that creates and maintains mobile apps for customers. We can no longer build iOS apps using MS-hosted agents that align with minimum security and OS version support requirements because we cannot use Xcode 26 on the MS-hosted MacOS version.
A issue was filed months ago as an Enhancement but at this point our builds are breaking so I'm creating this as a BUG I don't know what else to open the ticket as when it is for a failure to maintain provided services.
Either send a notification that you will no longer support something, or properly maintain it please - this is impacting our business already.
