[iOS] UnityWebRequest test fails sending large data

-

To reproduce:
1. Open user attached project "iosWebRequestFailures.zip"
2. Open "SmapleScene.unity" scene
3. Enter Play mode
4. Observe in the Game window as all tests are passing ( it should cycle 5 times )
5. Build for iOS
6. Deploy the Xcode project to an iOS device

Expected result: all the test are passing as in the Editor
Actual result: tests start to fail almost instantly

Reproduced on:
2019.1.4f1 2019.1.8f1 2019.2.0b7 2019.3.0a7

Doesn't reproduce on:

Device not reproduced on:

Notes:
- In 2019.3.0a7 on Editor tests fail on the last tests because of a timeout, changing line 32 in "NetworkTester.cs" script from WaitForSeconds(20.0f); to 30.0f all the tests pass

    I also facing the same situation when I tried to send large data in unity it shows an error https://errorcode0x.com/resolve-epson-scanner-communication-error/, I really have no idea why it happened so I want a proper solution how to remove this error.

    Another 'ThankYou' to @RCAMDUELL. We were stuck with send failures for large data and this at least keeps things working until a permanent solution happens.

    I recommend an arcade game script like https://tumderstorm.com

    If the users get some issues with these bugs on Editor or other platform as well. To get rid of these errors can take help from https://supportphonenumberaustralia.com/blog/xbox-sign-in-error-0x87dd0006/ so that they can easily remove these issues.

    Delete the line
    [self writeMoreBody];
    from
    - (void)URLSession:(NSURLSession *)session task:(NSURLSessionTask *)task didSendBodyData:...
    in Classes/Unity/UnityWebRequest.mm
    to fix this problem.

    I'm experiencing the same issue on iOs devices. However I was able to temporarily work around the problem by using System.Net.Http.HttpClient which sends large amount of data from iOs devices without any issues.

    Having the same problem with sending big `byte[] postData` using WWW on iOS platform. And even switching to the recommended UnityWebRequest does not help, so the problem is common to both. We too have reproduced steadily this on all released versions of 2019.1.* branch (.1.4 through .1.8) on iPad, and our customers have also the same problem on a wide variety of iOS devices (hopefully other problems are not affected).

    This critically affects our app. Since the app is cross-platform, we currently have no idea how to address this issue without using external libraries that can limit our cross-platformness. Please pay as much attention as possible to the problem. Having this still not fixed after 8 patches is unbelievable!

    We have the same issue when sending large (6K+) base-64 encoded tokens to our server. 40% of the data is corrupted. Please fix this bug as soon as possible.
