I set it up in iOS13 using private methods.
This is code:
[self.webView.configuration.processPool performSelector:@selector(_setCookieAcceptPolicy:) withObject:NSHTTPCookieAcceptPolicyAlways afterDelay:0];

On iOS13.It's working and policy is always.But on iOS14.It's failure and policy is never.Even though I set it NSHTTPCookieAcceptPolicyAlways.
So I think it is failure in iOS14 and I change my code，This code has been deleted.But when I updated my App，It‘s not working on iOS14!!!
I should uninstall my App and install,It can be works.
So is there any way to change it in iOS14？ In addition to uninstall.

We do not recommend using SPIs. If you can describe the overall goal, there may be a supported way that we can recommend.

webkit-help mailing list or Slack would be a better venue for this question, as changing an SPI behavior is not a WebKit bug.
