Automatically open the Safari Debugger when the iPhone Simulator is launched

Automatically open the Safari Debugger when the iPhone Simulator is launched


The iOS web debugger in Safari is the bee's knees, but it closes every time the Simulator is restarted. Not only is it annoying to re-open it from the menu after every build, but it makes it tricky to debug any behavior that happens during startup.

Is there a way to set up a trigger in Xcode to automatically open the Safari debugger after every build, or perhaps a way to build a shell script or Automator action to do a build and immediately open the debugger?

Humm,I don't think you can do that,but you can just "CTRL+R" in the web debugger.

There is question that should be marked a duplicate that describes using setTimeout() to give you enough time to switch windows over to Safari and set a breakpoint.

Something like this, where startMyApp is the bootstrap function of your app:

setTimeout(function () {    startMyApp();  }, 20000);  

It is super ghetto, but does work. I've submitted a feature request via http://www.apple.com/feedback/safari.html too to close the loop.

This is a partial solution. This opens the debug window of Safari with one click which is a lot better but not automatic.

Open Script Editor on your mac (Command + Space Bar and type in Script Editor)

Paste in this code:

-- `menu_click`, by Jacob Rus, September 2006  --   -- Accepts a list of form: `{"Finder", "View", "Arrange By", "Date"}`  -- Execute the specified menu item.  In this case, assuming the Finder   -- is the active application, arranging the frontmost folder by date.    on menu_click(mList)      local appName, topMenu, r        -- Validate our input      if mList's length < 3 then error "Menu list is not long enough"        -- Set these variables for clarity and brevity later on      set {appName, topMenu} to (items 1 through 2 of mList)      set r to (items 3 through (mList's length) of mList)        -- This overly-long line calls the menu_recurse function with      -- two arguments: r, and a reference to the top-level menu      tell application "System Events" to my menu_click_recurse(r, ((process appName)'s ?          (menu bar 1)'s (menu bar item topMenu)'s (menu topMenu)))  end menu_click    on menu_click_recurse(mList, parentObject)      local f, r        -- `f` = first item, `r` = rest of items      set f to item 1 of mList      if mList's length > 1 then set r to (items 2 through (mList's length) of mList)        -- either actually click the menu item, or recurse again      tell application "System Events"          if mList's length is 1 then              click parentObject's menu item f          else              my menu_click_recurse(r, (parentObject's (menu item f)'s (menu f)))          end if      end tell  end menu_click_recurse    menu_click({"Safari", "Develop", "Simulator", "index.html"})  

Once the simulator has opened, click run on your script (you might need to allow the script editor in the settings the first time).

(Optional) You can save your the scripts as an app so that you don't have to have the script editor open.

Combining Tom's answer with my solution, first do the following:

  • Create an application as Tom describes above
  • In "System Preferences -> Security & Privacy -> Privacy -> Accessibility" add your new Script Applicaiton and make sure it is allowed to control your computer

Now, I'm using cordova and from the command line the following builds, runs emulator and opens safari debug console:

cordova build ios; cordova emulate ios; open /Applications/Xcode.app/Contents/Developer/Applications/Simulator.app; sleep 1 ; open /PATH/TO/OpenDevelop.app/  

Make sure to replace /PATH/TO/ with the appropriate path to where you saved your script.

I realise this isn't a great solution, but adding an alert at the beginning of your JS will halt the process until "ok" is clicked - that gives you time to open the developer tools and then hit "ok" to effectively start your app.
