It's more issues with "3rd party" cookies. "app.hostname.tld" doesn't need to actually access the cookies at all, it just needs to make requests to "api.hostname.tld" which sets the cookies and then later validates them. Unfortunately safari blocks this use case unless you have also been to "api.hostname.tld" directly and there doesn't seen to be any easy way around it (outside of allowing all 3rd party cookies...) And while iOS safari now handles this (i think they allow *.hostname.tld to use 3rd party cookies for any other subdomains as long as hostname isn't a common provider or something?) it doesn't seem to work consistently for UIWebView or WKWebView hybrid applications. And the "allow 3rd party cookies" setting doesn't seem to apply to the web views either.
