Last week I finally updated macOS Big Sur (11.4) because the new Xcode requires a minimum version of macOS 11.0 or higher. However, during the development and debugging, I found that it used to be possible to debug the Web in Safari on iPhone, emulator or real iPhone, but now it is not possible.

This is the interface, without the elements, the network, and so on.

After some searching on the Web, I learned from Safari… – Apple Community after MacOS 11.4 update that you need to download safari Technology Preview, which allows you to debug the Web on your iPhone as before. Safari Technology Preview download page

After the installation, open the App, open the development menu, and open the corresponding debugging device

Now you can see the familiar inspector interface

At present, I have not found a way to convert into Chinese, but these English, generally can understand 🤠. If it’s macOS 12 Beta, I’ve heard that you can debug the Web by directly updating the new Version of Safari, but I don’t know if I’ve tested it. Current macOS 11 users can now debug the Web on their iPhone with Safari Technology Preview. Why Safari 14.1.1 doesn’t debug the Web like it used to? I just want to debug the Web😂 on iPhone

Based on this experience, I think 🤔 in the future, macOS and iOS will further merge. I wonder if the Web on iPhone will be changed by using Safari in the future? Wait and see, hahaha.
