I have a visionOS 2 project created on Xcode 16, when I updated to Xcode 26 beta5, I can't build it any more, every time it stuck in process like the picture shows below:
Already tried many methods to fix this issue, such as clear build folders, but don't work.

I ran into something like this in Beta 1 back in June. At first I thought it was something related to RealityKitContent as that is where Xcode seemed to be stuck. It ended up not having anything to do with RealityKit. One of my example code files demonstrated how to use every ornament anchor. This worked well on previous versions, but Xcode 26 could not compile it.
Can you look at your SwiftUI code and see if there is anything with lots of ornaments, toolbars, that sort of thing? You may want to start commenting out sections of the view hierarchy and see if you can get it to build. Once it builds, start re-activating views until you can cause the issue again. That may help you find the view that Xcode is getting stuck on.
