Oh so the problem is variant thinks it should try to manage memory for you? I 
tried doing:

  v: variant;
begin
  v := GetMem(100);

And that crashed also. I thought it would be ok to just hold the reference but 
not claim ownership over it.

I would be pleased to know where I can find the latest iOS parsed headers and possibly a hello 
program. Also, the cross compilers for iOS don't seem to be available at 
 on any of the listed mirrors.

Variants count as managed types and they can contain interface references
and strings. If you use a custom type you can do as you please, but the
internal types that can be assigned to a Variant *are* managed accordingly
(if the types themselves are managed).

The last ones I did are ancient now at iOS 8 (where at 13 now!).

Not sure if anyone else has bothered to update since then.

Looks like I made a little template project to get started with since I always 
forget this stuff myself.

(IIRC in case of native types there is another pointer in the variant 
which is an interface for something that manages the record.  But it has 
been a while)

I indeed somehow forgot to upload that installer. I've uploaded it now 
to Sourceforge and to the main FPC download mirror.

Never mind, I deleted them again. They contained FPC 3.2.0 installers, 
not 3.2.2 ones. I remember again that FPC 3.2.2 didn't build for iOS, 
and somehow I had accidentally packaged the 3.2.0 files in the 3.2.2 
installers. The building has been fixed on main IIRC, but I don't know 
if all necessary changes were merged back to the fixes branch.


Unless you need FPC 3.2.2-specific fixes, you can probably just use FPC 
3.2.0 instead for iOS.
