Ok, I checked the clang support for the "parenthesized initialization of aggregates" feature and it shows as supported in clang16.
I'm guessing xcode is just too outdated here and doesn't actually support c++20

[kd-11]

Also, you may want to try -std=c++20 instead of gnu++20

[shinra-electric]

Xcode supports up to C++23, though I don't know if it supports every feature.

Here is a list for your reference.

As far as I remember, the CI uses Xcode 14.0.

From that list it seems to not support the feature. But the CI version would also not work in that case. I hate that apple only shows what they support instead of a feature matrix including what they don't support. Clang however has this at https://clang.llvm.org/cxx_status.html
The section that is making the build fail is "parenthesized initialization of aggregates". We can work around it by replacing the construction with an initializer list.

I'm not able to install Xcode 14.3.1 to test, since I'm on macOS 14 and it won't run.

If you'd like I'll close this issue for now, and will re-open if it's still a problem once Xcode 15 gets out of beta. (Or if someone else on Xcode 14 can confirm it's not working there either).

#14070 should fix this
