Right. In the future we will probably add the ability to put explicit alignment/layout information on structure fields. This would be useful for this, as well as other cases where you’re trying to match a specific layout used in an on-disk file format or memory mapped device. That said, this doesn’t fit in the scope for Swift 4 stage 1. -Chris _______________________________________________ swift-users mailing list swift-users@swift.org https://lists.swift.org/mailman/listinfo/swift-users
