Alamofire returns nil always in request - ios

Usually Alamofire working nice with simple urls like:
"http://somesite.com/folder/file.json"
But when I use:
"http://somesite.com/folder/(jsonName.text).json
it always give me a nil... jsonName is a TextField as well...
That's the whole Controller:

How to pass data in a View Controller to a Collection View in another View Controller? [duplicate]

This question already has answers here:
Passing data between view controllers
(45 answers)
Closed 5 years ago.
I am trying to pass data in a UITextField that the user will input to go into a cell in a Collection View in another View Controller.
I want to create new 'posts' to be added to my feed every single time someone presses the 'upload' button, so the Collection View cell needs to somehow upload the given information and then clear the cell.
I don't know how to approach passing the data to the Collection View.
Here is my View Controller and my Cell code.
import UIKit
import Firebase
class UploadViewController: UIViewController, UIImagePickerControllerDelegate, UINavigationControllerDelegate {
#IBOutlet weak var previewImage: UIImageView!
#IBOutlet weak var postBtn: UIButton!
#IBOutlet weak var selectBtn: UIButton!
#IBOutlet weak var thisTextField: UITextField!
#IBOutlet weak var thatTextField: UITextField!
var picker = UIImagePickerController()
#IBAction func thisPhotoUpload(_ sender: Any) {
if thisTextField.text != "" || thatTextField.text != ""
{
performSegue(withIdentifier: "segue", sender: self)
}
}
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
var postCell = segue.destination as! PostCell
postCell.thisString = thisTextField.text!
postCell.thatString = thatTextField.text!
}
override func viewDidLoad() {
super.viewDidLoad()
picker.delegate = self
}
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
if let image = info[UIImagePickerControllerEditedImage] as? UIImage {
self.previewImage.image = image
selectBtn.isHidden = true
postBtn.isHidden = false
}
self.dismiss(animated: true, completion: nil)
}
#IBAction func selectPressed(_ sender: Any) {
picker.allowsEditing = true
picker.sourceType = .photoLibrary
self.present(picker, animated: true, completion: nil)
}
#IBAction func postPressed(_ sender: Any) {
AppDelegate.instance().showActivityIndicator()
let uid = FIRAuth.auth()!.currentUser!.uid
let ref = FIRDatabase.database().reference()
let storage = FIRStorage.storage().reference(forURL: "gs://instagram-f3f20.appspot.com")
let key = ref.child("posts").childByAutoId().key
let imageRef = storage.child("posts").child(uid).child("\(key).jpg")
let data = UIImageJPEGRepresentation(self.previewImage.image!, 0.6)
let uploadTask = imageRef.put(data!, metadata: nil) { (metadata, error) in
if error != nil {
print(error!.localizedDescription)
AppDelegate.instance().dismissActivityIndicatos()
return
}
imageRef.downloadURL(completion: { (url, error) in
if let url = url {
let feed = ["userID" : uid,
"pathToImage" : url.absoluteString,
"likes" : 0,

Right now I'm getting the error in my View Controller on the 'var postCell = segue.destination as! PostCell' line. The error says 'Bad Execution'
Any and all help would be great.
Segue.destination returns a UIViewController not a UICollectionViewCell
You should create a variable in the next viewcontroller and assign to it the text then show it there.
let vc = segue.destination as! NextViewController
vc.thisText = thisTextField.text!
vc.thatText = thatTextField.text!
And then in the NextViewController you will have the inputs in thisText and thatText

startCall func not working
You need to define delegate in viewcontroller' ViewDidLoad
let objOardView = CardView() // this is only test purpose
objOardView.socketdelegate = self

Send array by segue to new view controller swift iOS 9

// Do any additional setup after loading the view, typically from a nib.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
}
Do it like this instead
In your didSelectRowAtIndexPath pass the array
self.performSegueWithIdentifier("drinkSegue", sender: TableData[indexPath.row])
Here you need to pass the array to your DrinkViewController
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
if (segue.identifier == "DrinkSegue") {
// initialize new view controller and cast it as your view controller
let drinkViewController = segue.destinationViewController as! DrinkViewController
// your new view controller should have property that will store passed value
drinkViewController.passedValue = valueToPass
// declare myArray in your drinkViewController and then assign it here
// now your array that you passed will be available through myArray
drinkViewController.myArray = sender
}
}
Update
After I got your project I noticed that the issue you had was that you did drag a segue from the tableView to the drinksController directly - what happened is that didSelectRowAtIndexPath will not be called and your sender will always be nil drinkViewController.myArray = sender as! Drinks.
I changed that by dragging the segue from the viewController to the drinksController instead.
