Tree in Swift programming language -

-

i tried make tree swift using fonctionnal way

here code: 

//this code works struct testarbre {     var racine: int? }  let a0 = testarbre(racine:nil)    //this code stuck on error struct arbre {     var racine: int?         var feuillegauche: arbre?         var feuilledroite : arbre? }  let a1 = arbre(racine: 10, feuillegauche: nil, feuilledroite: nil)  let a2 = arbre(racine:5, feuillegauche:nil, feuilledroite:nil)  let a3 = arbre(racine:1, feuillegauche: a1, feuilledroite: a2);

and here error when running code:

<unknown>:0: error: unable execute command: segmentation fault: 11 <unknown>:0: error: swift frontend command failed due signal (use -v see invocation) command /applications/xcode6-beta.app/contents/developer/toolchains/xcodedefault.xctoolchain/usr/bin/swift failed exit code 254

structs value types. imagine how struct initialized: have struct arbre, system allocate memory members, int , struct arbre, system allocate memory members (an int , struct arbre), system allocate memory members (an int , struct arbre) . . . -> crash

you need make class.

if want struct containing reference same type done pointers in c.

why "typdef struct { struct s *s; } s;" containing pointer same type compile?
