Tell me how to get rid of the error in my method? has many options tried and still the image does not display on ViewContoller.
func detailObject() {
let query = PFQuery(className: "soccer")
query.findObjectsInBackground { (objects:[PFObject]?, error:Error?) in
if error == nil {
for objects in objects! {
let detailPrognozS = objects["detailPrognozS"] as! String
let detailTitleS = objects["detailTitleS"] as! String
let detailTextS = objects["detailTextS"] as! String
let imageDetail = objects["detailImageS"] as? PFFile
DispatchQueue.main.async { [unowned self] in
self.prognozDetail.text = detailPrognozS
self.textView.text = detailTextS
self.titleDetail.text = detailTitleS
}
imageDetail?.getDataInBackground(block: { (data:Data?, error:Error?) in
if error == nil {
if let imageData = data {
DispatchQueue.main.async { [unowned self] in
self.imageDetail.image = UIImage(data: imageData)
}
}
}
})
}
}
}
The code displays this error:
Fatal error: unexpectedly found nil while unwrapping an Optional value Error be in this line"self.imageDetail.image = UIImage(data: imageData)" and the app crashes...please tell me.I beg you...
