What changed from 2.35.0 to 2.36.0? I can't use xcframework binaries from 2.36.0 onwards

[decim92]

Hi, I use in my own framework AWSCore and AWSS3 xcframeworks but they are distributed dynamically, so host apps can install AWS from let's say cocoapods... but after 2.35.0 none of the new frameworks work (2.35.0 OK, 2.36.... Bad), they crash on app start with the following error:

If you're aware of this issue could you please help to solve it? what should I modify in my framework for this to work again?

The only change that we did was bump the minimum supported iOS version to 12.

Thanks for the response, it seems that way based on release notes (and skimming through the changes) but my projects use greater minimum supported version and as I said it happens even for newly created projects in latest Xcode 16.4

Did something change on compilation settings or Swift version? it would seem more plausible but I can't really know on my side
