strongMemory
Use strong write-barriers to backing store; use garbage-collected memory on copy-in.
Declaration
static var strongMemory: NSPointerFunctions.Options { get }Discussion
This is the default memory value.
As a special case, if you do not use garbage collection and specify this value in conjunction with objectPersonality or objectPointerPersonality then the NSPointerFunctions object uses retain and release.
If you do not use garbage collection, and specify this value in conjunction with a valid non-object personality, it is the same as specifying mallocMemory.
