Xcode 8 • Swift 3
use this to download the image if you want
func downloadImage(url: URL) {
print("Download Started")
getDataFromUrl(url: url) { data, response, error in
guard let data = data, error == nil else { return }
print(response?.suggestedFilename ?? url.lastPathComponent)
print("Download Finished")
DispatchQueue.main.async() {
self.imageView.image = UIImage(data: data)
}
}
}
Usage:
if let url = URL(string: "http://www.apple.com/euro/ios/ios8/a/generic/images/og.png") {
downloadImage(url: url)
}

hello thank you for replay now we fixed the error and the app still workin when we press in the profile tab but the profile image give me no a empty image {func setupProfile(){
if Auth.auth().currentUser?.uid == nil{
logout()
}else{
let changeRequest = Auth.auth().currentUser?.createProfileChangeRequest()
//userName.text = changeRequest?.displayName
usrnNameButton.isHidden = false
let uid = Auth.auth().currentUser?.uid
databaseRef.child("Users").child(uid!).observeSingleEvent(of: .value,
with: { snapshot in
if let dict = snapshot.value as? [String: AnyObject]
{
if let profileImageuRL = dict["pic"] as? String
{
//let url = URL(string: profileImageuRL)
//self.downloadImage(url: url!)
//self.PP.image = UIImage(data: data!)
//let resource = ImageResource(downloadURL: profileImageuRL, cacheKey: profileImageuRL)
self.PP.kf.setImage(with: profileImageuRL as? Resource)
}
if let coverImageuRL = dict["CoverPic"] as? String
{
self.coverPic.kf.setImage(with: coverImageuRL as? Resource)
}
}
})
}
}
}
