Trying to get devtools frontend to debug websites on iOS Device (using ios_webkit_debug_proxy) - Git clone - Open Workspace in XCode 10.2.1 (10E1001) - File > Workspace Settings >..>... Relative to Workspace - Build - Stop the test after build complete - cd to WebKitBuild⁩ ▸ ⁨WebInspectorUI.build⁩ ▸ ⁨Debug⁩ ▸ ⁨WebInspectorUI.build⁩ ▸ ⁨DerivedSources⁩ - run static file server - go to localhost:8080/Main.html * NOTES Expected to see blank devtools ui Changing to ?ws=websocket_debug_host to get debug site on safari on iPhone Building Blink and using inscpector.html works 1530674 1 hi 2019-04-26 08:16:51 -0700 If you're trying to build/run Web Inspector, please follow these instructions <https://trac.webkit.org/wiki/HackingWebInspector>. You may also find <https://trac.webkit.org/wiki/WebInspectorDebugging> useful. 1531078 2 me.arpitjain09 2019-04-28 14:15:12 -0700 I tried the steps and got it to build from the CLI. But I cant actually use it to debug a Safari tab, I expected - Blank devtools ui - Adding ?ws=websocket_debug_host to get debug site on safari on iPhone (like in chrome) 1546857 3 me.arpitjain09 2019-06-21 05:01:41 -0700 @Devin Rousso any updates 1546884 4 hi 2019-06-21 09:17:46 -0700 Loading Web Inspector from a web page is not currently supported. You need to run your local build of Webkit <https://webkit.org/running-webkit/> and open Web Inspector as you would in Safari (Develop > Show Web Inspector). If you want to inspect an a page in Safari on iOS: 1. enable Web Inspector on iOS (Settings > Safari > Advanced > Web Inspector) 2. connect your iOS device to your Mac 3. open a page in Safari on your iOS device 4. launch Safari on your Mac (follow the steps in the link above) 5. select Develop > [your device] > [your page in Safari] 1570543 5 me.arpitjain09 2019-09-13 03:15:18 -0700 Thee doubts 1. No way to Extract standalone Webkit WebInspector frontend from Webkit sources ? 2. So there is no way to connect to a Safari page on iOS without the step: `Dvelop > [your device] > [your page in Safari]` ? 3. No way to utilise ios_webkit_debug_proxy and get the debuggable pages and then debug them in a standalone Safari Tab ? 1570654 6 joepeck 2019-09-13 11:54:15 -0700 (In reply to Arpit Jain from comment #5) > Thee doubts > 1. No way to Extract standalone Webkit WebInspector frontend from Webkit sources ? You can extract the frontend as you have attempted. But if you are using it, then you must just provide your own "InspectorFrontendHost" global object to fill in the APIs that the Web Inspector frontend uses. In the past we included a Stub, but we don't anymore. You could provide your own stub. This is when we removed it: https://trac.webkit.org/changeset/217924/webkit https://trac.webkit.org/browser/webkit/trunk/Source/WebInspectorUI/UserInterface/Base/InspectorFrontendHostStub.js?rev=216602 > 2. So there is no way to connect to a Safari page on iOS without the step: > `Dvelop > [your device] > [your page in Safari]` ? Correct. That is the only supported way. > 3. No way to utilise ios_webkit_debug_proxy and get the debuggable pages and > then debug them in a standalone Safari Tab ? Correct. That approach has never been a supported way.
