    else
    {
        NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];
        AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:configuration];

        NSURL *URL = [NSURL URLWithString:url];
        NSURLRequest *request = [NSURLRequest requestWithURL:URL];

        NSURLSessionDataTask *dataTask = [manager uploadTaskWithRequest:request fromData:data progress:nil

         completionHandler:^(NSURLResponse * _Nonnull response, id  _Nullable responseObject, NSError * _Nullable error) {
             if (error)

Answer 1

since iOS9 initially you need to populate your info.plist file by the following values:

the query schemes

which schemes you intent to open in your app, you can extend to this list with your custom URL schemes, if necessary:

<key>LSApplicationQueriesSchemes</key>
<array>
    <string>http</string>
    <string>https</string>
</array>

the transport security

which defines excuses for the app to receive response from any type of back-end:

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

---

NOTE: I personally would not recommend to bypass the official app transport security protocols for you and for your end-users safety, but obviously if you have no control of the back-end, you might not have too many other choices. if you can control the back-end I highly recommend to read this documentation from Apple and make your server side secure enough for iOS9+.

Creating an Upload Task

NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];
AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:configuration];

NSURL *URL = [NSURL URLWithString:@"http://example.com/upload"];
NSURLRequest *request = [NSURLRequest requestWithURL:URL];
NSURL *filePath = [NSURL fileURLWithPath:@"file://path/to/image.png"];
NSURLSessionUploadTask *uploadTask = [manager uploadTaskWithRequest:request fromFile:filePath progress:nil completionHandler:^(NSURLResponse *response, id responseObject, NSError *error) {
if (error) {
    NSLog(@"Error: %@", error);
} else {
  //enter code here 
    NSLog(@"Success: %@ %@", response, responseObject);
}
}];
[uploadTask resume];
