NSAllowsArbitraryLoadsInWebContent
A Boolean value indicating whether all App Transport Security restrictions are disabled for requests made from web views.
Discussion
Set this key’s value to YES to exempt your app’s WKWebView instances from App Transport Security restrictions without affecting your URLSession connections. Domains you specify in the NSExceptionDomains dictionary aren’t affected by this key’s value.
In iOS 10 and later and in macOS 10.12 and later, if you include this key with any value, then App Transport Security ignores the value of the NSAllowsArbitraryLoads key, instead using that key’s default value of NO. For more information about how the OS version affects ATS behavior, see the NSAppTransportSecurity key’s Versioning section.
