I can, however, launch MobileMiniBrowser.app from Xcode. As far as I can tell, it's loading the locally built WebKit although I can't attach lldb to a WebContent process launched this way for whatever reason. 2027353 6 rniwa 2024-04-09 23:04:27 -0700 This appears to be caused by setupIOSWebKitEnvironment not setting __XPC_* environmental variables. Applying the following diff seems to solve this issue although trunk WebKit immediately hits a debug assertion trying to load any real web page. It can successfully load about:blank and some basic data URLs however. diff --git a/Tools/Scripts/webkitdirs.pm b/Tools/Scripts/webkitdirs.pm index abff7ad462a6..0042c11f70b8 100755 --- a/Tools/Scripts/webkitdirs.pm +++ b/Tools/Scripts/webkitdirs.pm @@ -2999,6 +2999,8 @@ sub setupIOSWebKitEnvironment($) prependToEnvironmentVariableList("DYLD_FRAMEWORK_PATH", $dyldFrameworkPath); prependToEnvironmentVariableList("DYLD_LIBRARY_PATH", $dyldFrameworkPath); + prependToEnvironmentVariableList("__XPC_DYLD_FRAMEWORK_PATH", $dyldFrameworkPath); + prependToEnvironmentVariableList("__XPC_DYLD_LIBRARY_PATH", $dyldFrameworkPath); prependToEnvironmentVariableList("METAL_DEVICE_WRAPPER_TYPE", "1"); setUpGuardMallocIfNeeded(); 2027354 7 rniwa 2024-04-09 23:08:33 -0700 Pull request: https://github.com/WebKit/WebKit/pull/27068 2027472 8 ews-feeder 2024-04-10 09:47:45 -0700 Committed 277304@main (c1593e5d86c1): <https://commits.webkit.org/277304@main> Reviewed commits have been landed.
