… in interfaces. The `convenience` keyword is not accepted on actor initializers because the compiler infers this status automatically and actors cannot be subclassed. However, internally the compiler still computes whether an actor init is a convenience init and this implicit status has been leaking through accidentally in printed `.swiftinterface` files. This was noticed because in Swift 6 the presence of the keyword is diagnosed as an error, making `.swiftinterface` files unparseable for modules containing actors with convenience inits. For Swift 6, I'm just going to suppress the error in `.swiftinterface` files regardless of language mode. In future releases of the compiler, though, it can stop printing the `convenience` keyword on these inits altogether, though. Resolves rdar://130857256.
