Macro Newbie Q: for testing, how to deal with different indentation?

I'm following along with WWDC Write Swift Macros.

I use 2 spaces for indent, however, this seems to mess with assertMacroExpansion:

 enum EasySlope {
   case beginnersParadise
   case practiceRun
–  init?(_ slope: Slope) {
–    switch slope {
–    case .beginnersParadise:
–      self = .beginnerParadise
–    case .practiceRun:
–      self = .practiceRun
–    default:
–      return nil
+
+    init?(_ slope: Slope) {
+        switch slope {
+        case .beginnersParadise:
+          self = .beginnersParadise
+        case .practiceRun:
+          self = .practiceRun
+        default:
+            return nil
+        }
     }
–  }
 }

Actual expanded source:

enum EasySlope {
  case beginnersParadise
  case practiceRun

    init?(_ slope: Slope) {
        switch slope {
        case .beginnersParadise:
          self = .beginnersParadise
        case .practiceRun:
          self = .practiceRun
        default:
            return nil
        }
    }
}

how to deal with this 2 spaces 4 spaces indentation difference?
also whole init block is indented an extra level?

is there a way to assert the syntax tree indeed of textual comparison, which is prone is miss spelling and space indentation conflicts.

assertMacroExpansion does accept argument for indentation value with label indentationWidth, you can pass .spaces(2) for indentation with 2 spaces.
