In tableview Data is Overwriting

I have two collectionView. One is main and second is sub items when i click both collectionView the data is added in tableView.

My requirement is like when I click on first collectionView it will be added in cart and tableViewCell should display it original price which I retrieve from web service.

Now when I click on second collectionView it should also added to tableview but when I click this it will have to display price as 0. To add into tableview i am using did select method of collectionView:

func collectionView(collectionView: UICollectionView, didSelectItemAtIndexPath indexPath: NSIndexPath) {
    let  dictSub = arr[indexPath.row] as! [String : AnyObject]
    //to insert product to top of tableview
    arrTable(dictSub, atIndex: 0)
    self.tbl.reloadData()
}

At cellForRowAtIndexPath method I am checking that isMainProduct equals to one or zero

code :

if  isFromMain == "1" {
    let Price   = NSString(string: pPrice1).floatValue
    let total   = 1 * Price
    cell.lbl.text = String(format: "%.2f", total)
} else {
    let Price   = 0.00
    let total   = 1 * Price
    cell.lbl.text = String(format: "%.2f", total)
}

When one it will add original price but when it is not from main product it will display zero.

Issue is:

First when i click on main collection view original price is displayed but when i clicked on sub items price of main product also changes to zero.

I want to prevent this data overwriting.

In your didSelectItemAtIndexPathyou are adding Dictionaryto Array, you can use this Dictionary to differentiate that it is coming from main collectionView or not instead of setting instance value of isFromMain to 1.

func collectionView(collectionView: UICollectionView, didSelectItemAtIndexPath indexPath: NSIndexPath) {
    var  dictSub = arr[indexPath.row] as! [String : AnyObject]  
    if collectionView == mainCollectionView {
        dictSub["isFromMain"] = "1"
    }
    else {
        dictSub["isFromMain"] = "0"
    }
    arrTable(dictSub, atIndex: 0)
    self.tbl.reloadData()
}

Now use this key to in cellForRowAtIndexPath to check it is coming from main CollectionView or from second one.

let dic = arrTable[indexPath.row] as! [String : AnyObject]
let isFromMain = dic["isFromMain"] as! String
if  isFromMain == "1" {
    let Price   = NSString(string: pPrice1).floatValue
    let total   = 1 * Price
    cell.lbl.text = String(format: "%.2f", total)
} else {
    let Price   = 0.00
    let total   = 1 * Price
    cell.lbl.text = String(format: "%.2f", total)
}
