Ref 1. In WWDC2016, Apple announced about web inspector entitlement.
"To protect the integrity of your app, we don't let just anyone download your app and use Web Inspector to poke around your app.
So you'll need to add this entitlement to your app's Entitlements File for local development.
... you add this while you're developing and then you take it back out when you ship your app. Then once you have this entitlement, your device and app will show up in the Develop menu and you can attach to it. And it's easy — just that easy to connect Web Inspector to your JSContext and WebViews."
Ref 2. The Guide of Webkit.org.
Once Web Inspector is enabled, connecting the iOS device to any macOS machine, either via a physical cable or after configuring wireless debugging in Xcode, the name of the iOS device will appear as a submenu in the Develop menu of Safari (and Safari Technology Preview) on the connected macOS machine, allowing for remote inspection of:
- any page in Safari
- websites added to the home screen
- web content in developer provisioned apps
- SFSafariViewController
- WKWebView
- UIWebView
- JSContext
Following these references, I created an entitlement file with 'com.apple.webinspector.allow = 1' and added it on my project.
Wrote the path of entitlements down on Code signing Entitlements - Debug.
After that, a build error has found "Provisioning profile doesn't include webinspector allow entitlement." and it's gone when I put "Any SDK" underneath of Debug path.
Changed build configuration to "Debug" and Archive.
Finally downloaded and install my app via FTP server but still can't debug WKWebView on mac safari. I still see grayed "No inspectable Applications." sentence.
I tried Xcode 12.4, the latest version of safari, safari technology preview also.
Did I miss something or it's not possible to inspect downloaded iOS application?
