IWDP does not detect webviews anymore on iOS 11.3 Simulator (Xcode 9.3-beta3)

[mykola-mokhnach]

Mac OS 10.13.3, Xcode 9.3-beta3

1. Install IWDP with brew
2. Start iPhoneX 11.3 Simulator and open Safari in it
3. Start ios_webkit_debug_proxy in terminal

Actual result:
No devices are shown in the list

Expected device:
The simulator should be shown in the list.
On the same system with Xcode 9.2 the output is

Listing devices on :9221
Connected :9222 to SIMULATOR (SIMULATOR)

It might be that Apple has deprecated debugging via TCP port in the recent Xcode SDK and it is only available via Unix socket (probably, because this is the only thing I can se in lsof output of launchd_sim process so far: /private/tmp/com.apple.launchd.r4UKA9gcsI/com.apple.webinspectord_sim.socket

hi @mykola-mokhnach thanks for the report, I'll take a look. the bad pard is I need to update OS to install new Xcode, it would take some time

xcode 9.3 is released, experiencing the same issue.

Upgraded to IOS on the device 11.03 and xocde 9.2 and facing below issue.

Unable to connect to iPhone (00000000000000blah)
Please verify that Settings > Safari > Advanced > Web Inspector = ON

ios_webkit_debug_proxy -V
ios_webkit_debug_proxy 1.8
Built with libimobiledevice v1.2.1, libplist v2.0.0

tried to reinstall libimobiledevice does not seem to work

hi @skansar the issue is not related to this thread please open another one, what does ios_webkit_debug_proxy -d show, any output? do you see webviews in Safari browser under Developer tab?

[artygus]

I confirm the issue is there. Looks like since XCode 9.3.3 there's a unix socket connection for each webinsepctord of simulator. The question is how to detect unix socket locations. One way is lsof (somewhat like appium/appium-ios-simulator#145), but I hope there's a better a way

Has there been any progress made on this?

[artygus]

all the updates will be posted in this thread, also everybody is welcome to contribute

I did manage to get it working once, but haven't been able to since. One thing to note is that I can't see the app in Safari Inspector, is this an indication that it's not an issue with IWDP? If not where is the issue?

[artygus]

Simulators from Xcode 9.3-beta3 and up are only inspectable in safari technology preview for now AFAIK. Just to clarify the issue is only about simulators and Xcode 9.3-beta3 (and up)

The same issue:
Xcode 9.3
ios_webkit_debug_proxy 1.8
Built with libimobiledevice v1.2.0, libplist v2.0.0

I've had some success in finding the unix socket via the method described in appium/appium-ios-simulator#145, then piping that socket over TCP to port 27753, which is where the proxy expects to find a connection. Once I've done that the proxy finds the simulator fine and I can open the debugger. (I'm not able to send commands over the console, but I just tested with iOS 10 and it doesn't work there either, so there must be some other issue going on)

I don't have any good suggestions on avoiding lsof, though.
