  Looks like you need to change the bluish part to:

             // or just a category 
             cat:( LPAREN! tCat:ID RPAREN! )
             { 
                  ## = #( #[ObjcCATEGORY, "categorie"], #tCat ); 
             }

  What you had:

                  #cat = #( #[ObjcCATEGORY, "categorie"], #tCat ); 
                  ##.addChild(#cat);

  ... first sets #cat to
      ObjCATEGORY
      + ID
  ... but ## is still ID, so "##.addChild(#cat)" then gives you:
      ID
      + ObjCATEGORY
         + ID

  Hope this helps,

      { ## = #( #[ObjcCLASS_DEF, "@interface"], ##); }
     ;

    but doesn't work exactly as intended...
    I have a tree like
    ObjcCLASS_DECLARATION
        + ID /* tName */
        + ID /* my cat name */
            + ObjcCategory
                + ID /* my cat name */

    instead of
    ObjcCLASS_DECLARATION
        + ID /* tName */
        + ObjcCategory
            + ID /* my cat name */


    ?? quite puzzling ...

      here (in red) I tried to edit a portion of my tree, but that didn't work.. any idea?

      objcClassDefinition
       : AT_INTERFACE! tName:ID
        (
                 // 1st declaration
                (COLON! ID)? /* super class */
                (objcProtocolList)? /* protocols */
                 // instance variable
                (
                      LCURLY
                      ( declaration ) *
                      RCURLY
                 )?
            |
                 // or just a category 
                 LPAREN! tCat:ID RPAREN!
                 { #tCat = #( #[ObjcCATEGORY, "categorie"], #tCat); }
        )
        ( objcMethodName SEMI!  ) *
        AT_END!
        { ## = #( #[ObjcCLASS_DEF, "@interface"], ##); }
       ;
      protected objcProtocolList
       : LT! ID (COMMA! ID) * GT!
        { ## = #( #[ObjcPROTOCOL, "@protocol"], ##); }
       ;
