ios - how do you append tableview cells to correct headers? -


i have 2 viewcontrollers. in viewcontroller1, can select items. when item selected stored in core data. in viewcontroller2 want present items selected tableview headers.

some pictures (can't embed because of reputation):

as can see on these photos, alright when same item selected. when select new item gets duplicated. because of row code:

func tableview(_ tableview: uitableview, numberofrowsinsection section: int) -> int {    return cartarray.count }

so counts 2 items , both sections 2 items. wondering how append item under correct section.

my coredata array this:

[<cart: 0x6180004810e0> (entity: cart; id: 0xd000000002940000 <x-coredata://e4d1962c-c414-4c3a-a3bd-b300be78c00b/cart/p165> ; data: {     selectedcategory = shirts;     selectedid = 101;     selectedname = "white shirt";     selectedprice = 110;     selectedquantity = 2; }), <cart: 0x6180004828a0> (entity: cart; id: 0xd000000002980000 <x-coredata://e4d1962c-c414-4c3a-a3bd-b300be78c00b/cart/p166> ; data: {     selectedcategory = dresses;     selectedid = 103;     selectedname = "blue dress";     selectedprice = 125;     selectedquantity = 1; })]

and sections:

public func numberofsections(in tableview: uitableview) -> int {      return cartarray.count   }

and title:

func tableview(_ tableview: uitableview, titleforheaderinsection section: int) -> string?{      let sections = cartarray     let currentsection = sections?[section]      return currentsection?.selectedcategory  }

thanks!!
