Failed to load image to Firebase (unrecognized selector)

(BTW, I've read all similar questions on SO, please don't blame me, if my mistake is stupid)

I'm trying to upload image, that I get from imagePicker and resized then

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : AnyObject]) {
    if let pickedImage = info[UIImagePickerControllerOriginalImage] as? UIImage {
        process(pickedImage)
    }
    dismiss(animated: true, completion: nil)
}

func process(_ image:UIImage) {
    print("start processing")
    let resized = resize(image, size: 256)
    photo.image = resized
    let ref = FIRStorage.storage().reference().child("path/to/file")
    let data = UIImageJPEGRepresentation(resized, 1.0)
    let md = ref.put(data!)
    md.observe(.success, handler: { (snap) in
        //Something onSuccess
    })
}

func resize(_ image:UIImage, size w:CGFloat) -> UIImage {
    let scale = CGFloat(w)/image.size.width
    let newHeight = image.size.height * scale
    UIGraphicsBeginImageContext(CGSize(width: w, height: newHeight))
    image.draw(in: CGRect(x: 0, y: 0, width: w, height: newHeight))
    let newImage = UIGraphicsGetImageFromCurrentImageContext()
    UIGraphicsEndImageContext()
    return newImage!
}

This throwing error on ref.put(data!)

*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSConcreteURLComponents queryItems]: unrecognized selector sent to instance 0x1b093740'

Issue here is that queryItems isn't supported on iOS 7 (which I assume you're targeting). The next client version will support iOS 7 by using the query property instead.

In the mean time, you can target 8+, and it will work, while waiting for a fix for 7.
