Where is Instruments iOS AutoLayout Tool in Xcode 10?

At WWDC Apple promised to release a new Instruments tool for debugging AutoLayout on iOS. It should be released "later". I couldn't find it in the Xcode 10.0.0 release version. Did I overlook something, or didn't Apple release it yet?

Solution

  • The Instruments tool that they are talking about in the video has not been released yet (as of Xcode 11 beta 5).

    However, there is already an older Instruments tool which might help you debug Auto Layout on iOS. I tested the tool on an iPhone simulator in Xcode 10.2 and that works. However, I am not sure if it works on an actual device.

    Here's how to access it:

    1. Create a new Standard > Blank template.
    2. Click on the + button > search for the Cocoa Layout template.
    3. Once you have the Cocoa Layout template, it is possible to save it as a custom template so that you can access it directly from Custom > Your Template next time.

    There is an old but nice tutorial for this tool here.
