Same here. I am still seeing the same issue. Even on beta 5.

For me I'm no longer getting the Block pointer is missing a nullability type specifier (_Nonnull, _Nullable, or _Null_unspecified) I am just getting Multiple declarations of method 'insert siri intent method here' found and ignored. @developer555 did you change anything in your project or did you just upgrade to Xcode 13 RC and it fixed itself?
