Viewing CALayers in Debug View Hierarchy

Question

I was trying to work on a layer-hosting View in Objective-C as per the documentation

view.layer = [CALayer new];  // Create a layer-hosting view as opposed to a layer-backed view
view.wantsLayer = YES;

I go on to use this layer-hosting view to support a hierarchy of layers by appending further layers using addSubLayer.

Now my query is whether it's possible to view these children/hosted CALayers in the Debug View Hierarchy? I only see the NSViews but not the hosted layers. I was seeking something akin to what's available in Visual Studio as the Live Visual Tree where it shows both the platform views and the Visual layers.

Answer 1

Yes you can, when in the Debug View Hierarchy, click on Editor -> Show Layers, like so:

This feature was made possible from Xcode 11.4 onwards: https://twitter.com/hrrsn/status/1225168226507612161

So unfortunately you will need to upgrade your Xcode 11.3.
