The issue was that NSLocalNetworkUsageDescription in Info.plist seems to be mandatory on iOS 18.1 now, which it was not in iOS 17.
As far as I remember my tests on the released iOS 18.0 and its late betas, it was not mandatory. Since I don't have an iOS 18.0 device anymore and simulators don't check, I cannot reproduce it there.
Thanks for the link to TN3179 which is not clear about NSLocalNetworkUsageDescription being mandatory on iOS apps, but gave me the right hint.
