[swift-dev] Questions about ARC

Hi, I am new to Swift, and I have several questions about how ARC works in Swift. 1. I read from one of the previous discussions in the swift-evolution list ( https://lists.swift.org/pipermail/swift-evolution/Week-of-Mon-20160208/009422.html) that ARC operations are currently not atomic as Swift

Re: [swift-dev] High-level SIL Optimization: How do I get a FuncRef from the stdlib?

What is the generic signature of the method you’re generating the call to? if it’s always something like func foo(a: Array) ie, single generic parameter, without any constraints, then you can manually create a single-element substitution list with no conformances. Slava > On Nov 29, 2016, at

Re: [swift-dev] Questions about ARC

Thanks for clarifications. I have a couple of follow-up questions. 1. Could you please provide more information (e.g. source code location) about the optimization applying non-atomic reference counting? What's the scope of the optimization? Is it method-based? 2. Looking at the source code, I

Re: [swift-dev] Questions about ARC

Thanks for providing the pointer. Do you have any preliminary result or goal (e.g. the replacement ratio) of the optimization? Is it going to replace all ARC operations with non-atomic ones for single-threaded applications? On Wed, Nov 30, 2016 at 8:50 PM Roman Levenstein wrote: > On Nov 30, 20
