Code completion is more or less defunct in 13.2.1 on my system. Almost all functions from Apple frameworks have "everything" as a suggestion for code completion. Xcode does not prioritize the actual method fingerprint up top.
E.g. HKSampleQuery from HealthKit does not list the available overloads.
Further, jumping to declaration does not work most of the times as well as looking up documentation.
At least SwiftUI previews are working again which failed in 13.2.
Does anybody have a hint if there is a command line parameter to advise Xcode to rebuild its code completion index?
