AFAIK there’s no iOS/iPadOS browsers offering dev tools. For me, as a web developer, it’s one of the biggest obstacles for developing as a digital nomad. I’m able to use GitHub Codespaces to run a server (it would be awesome to run a local one offline - but it’s a good work around).
The workaround for getting client side logs is having to install a client-to-backend logging service like Sentry and console.log lots - a better experience would be the Safari/Chromium Dev Tools on iOS.
