I'm attempting to fix some performance issues in our HTML5 game under iOS 8. I've got the Yosemite beta, and Safari 8.0 on a Mac. I seem to have lost the JS Profiling tool. According to the iOS developer center:
To start profiling manually, click the record button in the top right of the Profiles pane, and select Start JavaScript Profile in the resulting menu.
(from here)
On Safari 8, I don't get a menu with that option, it just starts recording a timeline. Where has this moved to?
Enable Web Inspector on iOS On your iOS device navigate to the Settings app and scroll down and select the Safari entry. Inside the Safari settings screen scroll to the very bottom and select the “Advanced” option. Then, within the Advanced section, toggle on the “Web Inspector” option.
How do I know if JavaScript is working on Apple Safari? JavaScript is enabled by default in Apple Safari, but you can verify if yours is active through the Safari tab. To do this, simply click on "Safari" at the top left of your screen to expand the Menu. Next, click on Preferences to reveal the Safari Preferences section.
Be it an iPhone 11, iPhone 10 or MacOS device, the steps in this guide will help you learn the simple process and benefits of enabling the JavaScript feature on your Safari browser. Javascript is enabled in your web browser.
Open the Safari application by clicking on an icon that appears like a compass in your bottom toolbar. 2. Click on the “Safari” menu at the top left corner of the browser. 3. Under the Safari menu, find and click on “Preferences”. This will open a pop-up menu. 4. Move your cursor over to the “Security” tab and select it. 5.
It would seem as if the profiling has been replaced with the "Records"-section which provide some of the same info, although not all of it.
As mentioned in the comments, in order to find the Records section click Timelines, then JavaScript & Events in the timelines which will show "Records" in the lower left corner.
