The stride of an Array<T> is the width of a pointer, since Arrays are stored indirectly. Also, the allocated capacity may be greater than the number of elements actually contained in the Array. If you want a fixed-size group of elements, with a stride equal to the number of elements multiplied by the per-element stride, use a tuple. - Karl _______________________________________________ swift-evolution mailing list [email protected] https://lists.swift.org/mailman/listinfo/swift-evolution
