Answer 1

In iOS 9, SSL connections will fail for all invalid or self-signed certificates. This is the default behavior of the new App Transport Security feature in iOS 9.0 or later, and on OS X 10.11 and later.

You can override this behavior in the Info.plist, by setting NSAllowsArbitraryLoads to YES in the NSAppTransportSecurity dictionary. However, I recommend overriding this setting for testing purposes only.

For information see App Transport Technote here.
