Xcode 26.5 is running insanely slow and throwing up errors on code that has no errors. The code will finally compile but it takes forever. It's almost unusable.

Using Xcode 26.3 on a MacBookPro with M3 Max chip and 36 GB memory, my system is running very slow in loading programs and in compiling, compared to older Xcode versions.

How do you add support?
