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.
