How to pass value from collection view to table view

I am displaying below data in collection view.

And my JSON data is like:

data {

type : max
id  : 1234

type : vete
id : 3445

type : tomoe
id : 2220

type : matye
id : 9087

}

Same like each type have some data like for example:

Type: max id: 1234

This above type have:

[
{
name : max 1
description : masncj

name : max 1
description : masncj


name : max 2
description : masncj


name : max 3
description : masncj


name : max 4
description : masncj


}
]

And I am displaying the above data name, description in table view.

Now what I need is, when ever I click any data type name like max, vete, tomoe, etc. In collection view.

I need to redirect to table view as push segue and in that table view I need to display the respective data.

Like if I press max type name cell in collection view - then it have to redirect to table view and there I need to populate max1, description.

I need to use one collection view and one table view controller for this.

How can I pass the type id and how can I see the respective data - when I press any data in collection view - I need to shoe that respective data names, description in table view?

    func tableView(_ tableView: UITableView, heightForHeaderInSection section: Int) -> CGFloat {

Firstly create a segue from CollectionViewVC to TableViewVC using Storyboard and give it a identifier name something like "collection_to_table".

Create a variable name typeId in both the View controller as

var typeId = ""

Now in CollectionViewVC On click on type , perform this

typeId = <actualTypeId> //This is dynamic value from your json   
performSegueWithIdentifier("collection_to_table", sender: self)

Now override a method in CollectionViewVC 

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject!) {
         if segue.identifier == "collection_to_table"
        {
            let secondVC : TableViewVC = segue.destinationViewController as! TableViewVC
            secondVC.typeId = typeId
        }
    }

Now You have typeId value in TableView Which you can use to fetch info.

Hope this help you . Let me know if you find it hard to understand .
