That's odd. I've written plenty of macOS networking code and not seen this problem. What is the errno value? The only thing I can guess is that the Xcode test-runner process is being sandboxed to prevent outgoing networking, but I've definitely run TCP connections from XCTests without problems. Are you connecting to "localhost" / 127.0.0.1, or using an explicit IP address? —Jens _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
