Minimum Deployment target being ignored for SwiftPM packages in Xcode 26?

In XCode 26 Beta 5, SPM packages seem to be ignoring my minimum deployment target.

I see warnings like:

SKProductsRequestDelegate' is deprecated: first deprecated in iOS 18.0 - Get products using Product.products(for:) 

but my deployment target is iOS 17. This warning doesn’t show up in Xcode 16. If i turn on warnings as errors, it’s an error and halts compilation.

It seems like maybe this is specific to StoreKit and StoreKit 1 is no longer supported, even on older deployment targets, even though it’s a warning ?
