I imagine there’s a direct way, but I can’t find it in a program. You can do something like this: strideofValue (foo [0]) // but this requires foo.count != 0, or: strideof (foo [0].dynamicType) // which seems to work in a playground even for empty arrays Note that I’m not sure there’s an API guarantee that the Array<> elements are stored contiguously in memory. If you want that, you should probably use ContiguousArray<> instead. (That also gives you API to directly/unsafely access the memory too, IIRTGHF** correctly.) Do be careful, though. If you’re accessing Ints raw-ly, and (say) saving them or transmitting them to another application or platform, you might also have to worry about element size and endianness differences, theoretically. ** "If I Read The Generated Header File" _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
