 <?php
$uploaddir = 'uploads/';
$file = basename($_FILES['uploadedfile']['name']);
$uploadfile = $uploaddir . $file;

echo "file=".$file; //is empty, but shouldn't

if (move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $uploadfile)) {
    echo $file;
}
else {
    echo "error";
}
?>

<key>NSAppTransportSecurity</key>  
 <dict>  
      <key>NSAllowsArbitraryLoads</key><true/>  
 </dict>

It seems you change the format of image to .png by manually. Please try to upload the image with original format.
