I’m getting really frustrated so I’m just posting it because I’m sure there’s an easy answer but it makes no dang sense.
I have this request to load products from a database
self.fetchFlashDealsWebServiceCall()
That request then sets my products, and only returns 10 at a time due to pagination from the server
What’s frustrating me is I need to know the max pages, and it’s returned in the request, and I set it in the request, and I understand that completions can make it so variables aren’t set properly sometimes but the products load, the variables are set properly, and it’s just this one gosh dang property that won’t set. I have tried a lot of options, and I’m just at the end of my rope with this stupid variable. I’ve verified it IS set properly inside of status but everywhere else (including at the end of the fetchDataFromServer) it is nil. I could set it to not be optional but that means I have to set it inside of the viewDidLoad function and that won’t work either because I have to wait for the request to know.
Set the variable under the ViewController with var maxPages: Int?
Fetch Request
webService_obj.fetchDataFromServer(alertMsg: false, header:headerTxt, withParameter: PostData as NSDictionary, inVC: self, showHud: false){ (response,message,status) in
if status{
let data = response.value(forKey: "data") as! [String: Any]
let totalPages = data["totalPage"]
self.maxPages = totalPages as? Int
self.homeBannerData = data["baner"] as! [[String : String]]
self.imagesbanner = self.homeBannerData.map{ $0["image"]!}
if self.currentPageNumber == 1 {
self.productData = data["product"] as! [[String:String]]
} else {
self.productData.append(contentsOf: data["product"] as! [[String : String]])
}
self.isPageRefresing = false
} else {
self.productData = []
}
if self.productData.count > 0 {
self.lbl_no.isHidden = true
} else {
self.lbl_no.isHidden = false
}
print("maxPages == (self.maxPages) in Fetch Request")
self.collectionview_list.reloadData()
}

If I print totalPages it’s Optional(6)
then if I print self.maxPages after setting it it’s nil

So apparently Swift is just idiotic sometimes and I had to typecast the (clearly) Int value to a String with the following
and that worked to give the
Optional(6)value to my int. Single most frustrating thing that doesn't make any sense to me that I've ever dealt with but hopefully this helps someone.This is a bit more "robust" and safer way to parse that value:
