Bad File Descriptor crash SelectorEventLoop Xcode 14

[danielbowden]

Hi, v4.1.4 resolved the memoryRebound fatal error on Xcode 14 / iOS 16 that we were seeing but there is also another issue in SelectorEventLoop.

Embassy/SelectorEventLoop.swift:88: Fatal error: 'try!' expression unexpectedly raised an error: Embassy.OSError.ioError(number: 9, message: "Bad file descriptor")
2022-10-28 01:08:39.731236+1100 XYZUITests-Runner[81238:5120563] Embassy/SelectorEventLoop.swift:88: Fatal error: 'try!' expression unexpectedly raised an error: Embassy.OSError.ioError(number: 9, message: "Bad file descriptor")

This looks like it was also raised in envoy/Ambassador#67 but I thought I'd add it here for more visibility.

We've tried cleaning up the event loop vars between tests, sharing a single instance of the server, and various other tweaks but no luck. Our use of Embassy is an almost identical setup to described here: https://envoy.engineering/embedded-web-server-for-ios-ui-testing-8ff3cef513df#.c2i5tx380

Any help or ideas would be appreciated.

Xcode 4.0.1
Embassy 4.1.4
macOS 12.6
Simulator iOS 16.0

Where you able to find a workaround?

We are seeing this crash in our projects after upgrading to Xcode 14, no workaround found yet.

We're seeing a similar exception in line 80
If it's known those methods can throw why not make the containing func throwing and pass the exception up to the user of the lib?

Our issue seems to have been fixed with #105
