Init accessors fail to parse in playgrounds

Using Swift
1

Hi,

Experimenting with init accessors I ran into the issue of not beeing able to use them from Xcode playgrounds. A simple newly created playground containing only the Angle struct example from the init accessors proposal triggers an expression failed to parse (no further compiler diagnostics) console error when being run. I tried with Xcode 16.3 and Swift 6 as the version playground setting. There are no issues when using this struct in an Xcode project or with Swift REPL, so not sure if this a compiler issue or a playgrounds issue?

struct Angle {
  var degrees: Double
  var radians: Double {
    @storageRestrictions(initializes: degrees)
    init(initialValue)  {
      degrees = initialValue * 180 / .pi
    }

    get { degrees * .pi / 180 }
    set { degrees = newValue * 180 / .pi }
  }

  init(degrees: Double) {
    self.degrees = degrees
  }

  init(radiansParam: Double) {
    self.radians = radiansParam
  }
}
