Thanks for the quick reply. Sure, I'm aware that this is not the best place to place bug reports. I post here in hope to hear a confirmation from other developers before filing a bug report.

Apple engineer confirmed that this is the expected behaviour: According to RFC 2732 Section 2, IPv6 addresses must be enclosed in [ and ] when it’s part of an URL. In this particular case, the host should be ipv6URLComponents.host = “[2001:0000:3238:dfe1:0063:0000:0000:fefb]”. I can confirm that the suggested solution works in iOS 16. However, the problem is that it is only a workaround, since enclosing IPv6 address in [] does not work in iOS 15 and older. So I still need to use if #available(iOS 16.0, *) {} syntax if I want my code to work in both iOS 15 and 16. I don't expect any updates regarding the issue. Just posting this in case someone with the same problem lands here.

Thanks for the response. Yes, the problem persists on iOS 16.0b4 as well. I submitted a bug - FB11287912

Hi! From what I can see, the issue is still not fixed. Is there any info about this one? Tested in iOS & iPadOS 15.2 Beta 4.
