I just installed Xcode 26.4 RC (17E192) yesterday and found that the documentation window now omits Foundation for me. Searching for "Date" finds the date property from GameKit, Core Data, ... but no Date type.
I was previously using 26.4 beta and this was not the case.
Is anyone else seeing the same thing?
Yep, seeing the same thing.
There's a lot of other stuff broken with Xcode 26.4. For example, the Swift symbol NSTextAttachment.character is gone and we have to use NSAttachmentCharacter which in turn produces an error when compiling with Xcode 26.3 and earlier. (FB22341879). And then there's the broken Claude Agent support which forces you to re-login every few hours.
Paired with the fact that macOS 26.4 cannot run Address Sanitizer builds from Xcode 26.3 and earlier, and you thus HAVE to use Xcode 26.4, I'm very frustrated with Apple's software quality right now.
