Do you have a counter benchmark? The burden is on you here to disprove the data presented. What that benchmark shows is that you spend A TON of time counting references, much more than tracing GC, unless you enter Swifts C++ networking code. I would think games don’t spend most of their time calling into networking code.
> In reality, a lot of Swift apps are delegating to C code. My own app (in development) does a lot of processing, almost none of which happens in Swift, despite the fact I spend the vast majority of my time writing Swift.
So what you’re saying is that any language will be good for gaming since they all can delegate to C?
> Swift an excellent C glue language, which Java isn't. This is why Swift will probably become an excellent game language eventually.
What makes swift better at calling C than Java? AFAIK Java has a perfectly good and brand new foreign function interface.
> This is why Swift will probably become an excellent game language eventually.
I would take this bet that it won’t. Purely on the sheer fact that gaming occurs on Windows and Swift is barely capable there.
> I would think games don’t spend most of their time calling into networking code.
Exactly. That is why the out-of-date networking example being touted as evidence is irrelevant here.
What it boils down to is that Java and C have fundamentally incompatible memory models. Direct access to C memory is impossible because of the managed heap and GC.

This is a very odd comment - gaming occurs in a lot of places. Quite a lot happens on mobile these days. Turns out a lot of mobile devices run Swift, on which it appears to be reasonably capable.
