WebKit has historically made running MiniBrowser from Xcode with a freshly built WebKit a one-click process. This worked because the "All Source" scheme had the MiniBrowser app set as its executable, so you could just hit ⌘R and it would launch it for you. https://bugs.webkit.org/show_bug.cgi?id=239301 broke this, justifying the change by mentioning that "All Tools" contains MiniBrowser. However, that scheme was never updated to point at the MiniBrowser executable. To make matters worse, in a future change (https://bugs.webkit.org/show_bug.cgi?id=243806) the WebKit build was pulled out of "All Tools" entirely. Furthermore, the "MiniBrowser" scheme mentioned as the intended way to build the stack through WebKit does not do anything but build the app, because it does not depend on anything. (In fact if you try using it the build just fails.) To avoid confusion, WebKit should bring back the one-click flow for running MiniBrowser. It would be nice if this could be made obvious via documentation or better naming too, but let's start with something small first :)
