It’s hard to answer that without knowing how you’re intended to use these techniques. If you can explain more about where you’re going with this, I should be able to make some specific recommendations. For example, if you’re goal were to pass a Swift object to a C API that takes a callback function pointer and a ‘cookie’ value, and hen calls that function with that cookie (like the `qsort_r` function), the to/from opaque mechanism provider by `Unmanaged` is the recommended way to pass a Swift object through such a cookie value. > 3. Is it possible to get the memory address of immutable value type (declared > as let) No, because such values don’t necessarily exist in memory.
