RecursiveDescrpition isn't purging pointers

[oliverfoggin]

I'm using V1.9.0 of SnapshotTesting and when running the as: .recursiveDescription tests it doesn't appear to be purging the pointers.

The code shows that it should be...

Copied from the framework...

extension Snapshotting where Value == UIView, Format == String {
  /// A snapshot strategy for comparing views based on a recursive description of their properties and hierarchies.
  public static func recursiveDescription(
    size: CGSize? = nil,
    traits: UITraitCollection = .init()
    )
    -> Snapshotting<UIView, String> {
     ...
        return purgePointers(
          view.perform(Selector(("recursiveDescription"))).retain().takeUnretainedValue()
            as! String
        )
      }
  }
}

But when I run my tests (for a second time) they are failing with a warning like...

@@ −1,1 +1,1 @@
−<UIWindowLayer: 0x60000212e550>
+<UIWindowLayer: 0x600002df9350>

I am not fluent enough in regex-ese to understand if this is correct though...

func purgePointers(_ string: String) -> String {
  return string.replacingOccurrences(of: ":?\\s*0x[\\da-f]+(\\s*)", with: "$1", options: .regularExpression)
}

Is there something I am doing incorrectly or possibly missing an option which is doing this?

Thanks

Nevermind... we're using a confusing wrapper that is actually not doing what I thought it was doing.
