URL(string: "127.0.0.1:8000/test") doesn't create a valid URL anymore with Xcode 15 Beta 5

With Xcode 15.0 Beta 5 (swift-driver version: 1.87 Apple Swift version 5.9 (swiftlang-5.9.0.124.4 clang-1500.0.38.1)) I can't create a valid URL with the following String:

URL(string: "127.0.0.1:8000/test")

With Xcode 14.3.1 (Apple Swift version 5.8.1 (swiftlang-5.8.0.124.5 clang-1403.0.22.11.100)) this worked without any problems.

Does anyone know if this is a bug or intentional?
