It's a little trickier than that. We only support Swift refcounting object headers on non-Darwin platforms, since there's no universal objc_retain implementation to fall back to. Blocks don't use Swift-compatible refcounting with the current runtime. -Joe _______________________________________________ swift-dev mailing list swift-dev@swift.org https://lists.swift.org/mailman/listinfo/swift-dev
