Swift: didSelectItemAtIndexpath function not work of json

Question

i have three Controller. in first CategoryCollectionViewController, next listTableViewController and finally has DescriptionCollectionViewController. in Controllers passed json data perfectly. but i got no idea what code i should write in didSelectRowAt_indexPath function of ListTableViewController.

The first CategoryCollectionViewController

override func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) {

    let controller1 = ListTableView()
    controller1.product_id = arrCategory[indexPath.item].id!
    navigationController?.pushViewController(controller1, animated: true)
}

** CategoryCollectionViewController Json web file**

The second ListTableViewController

override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {

tell me please what code i have to write here for push ViewController

ListTableController and DescriptionCollectionViewController's json web file is same

just different is product_image value have to load in ListTableViewController's cell and all_images value have to load in DescriptionCollectionViewController's cell.

What exactly are you trying to achieve on `didSelectRow`? Please format your question and ask specific problem. The question, in it's current state, is very broad and unlikely to receive any relevant answers — Malik, Sep 11 '17 at 07:03

You have to write this code for pushing view-controller after setting the Storyboard Id:

override func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) {
    let controller1 = self.storyboard?.instantiateViewController(withIdentifier:"ListTableView") as! ListTableView
    navigationController?.pushViewController(controller1, animated: true)
}

I am assuming that the StoryBoard Id will be same as your controller class name so you can set StoryBoard Id in StoryBoard -> identity inspector.

NOTE:- Replace the identifier in case of push another view controller Just like that:

let controller1 = self.storyboard?.instantiateViewController(withIdentifier:"DescriptionCollectionViewController") as! DescriptionCollectionViewController

i am coding programmatically. next i want to push from ListTableController to DescriptionCollectionViewController. in there your code is not working. – Quiet Islet Sep 11 '17 at 07:18
Okay, whats error you are facing? Also, you can replace the name of view-controller. – Salman Ghumsani Sep 11 '17 at 07:21
after write this code `func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) { let layout = UICollectionViewFlowLayout() let controller1 = DescriptionCollectionView(collectionViewLayout: layout) controller1.product_id = arrProduct[indexPath.item].id! navigationController?.pushViewController(controller1, animated: true) }` i got message `DescriptionViewController `Value of type 'DescriptionCollectionView' has no member 'product_id'` – Quiet Islet Sep 11 '17 at 07:26
i am working without storyboard, it is programmatically everything. – Quiet Islet Sep 11 '17 at 07:32
Basically, you have to set the storyboard-id in order to access the view-controller.. – Salman Ghumsani Sep 11 '17 at 07:34

You function will be something like that.

override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
let controller1 = NextViewControoler()
    controller1.data = dataSource["products"]["data"][indexPath.row]
    navigationController?.pushViewController(controller1, animated: true)
}

Description

dataSource will be that variable who store the JSON data.
dataSource["products"] will give you the key-value dictionary. dataSource["products"]["data"] will give you another key-value dictionary which contains the array of data.
dataSource["products"]["data"][indexPath.row] will give you the selected item dictionary.

Please note that you might need to do some casting to get your required data.

What value you want to pass to DescriptionCollectionView? – Usman Javed Sep 11 '17 at 07:46
It says that you have not declared any variable names data. – Usman Javed Sep 11 '17 at 07:47
please verify what value will return this arrProduct["products"]["data"][indexPath.row] statement. – Usman Javed Sep 11 '17 at 07:47
