Reveal 14: 🤘🏻

A new release of Reveal (v14) is available to all users with a current license, and as a 14-day trial.


  • Reveal now prefers using Metal over OpenGL for Canvas rendering when running on macOS High Sierra. This significantly improves performance on computers without discrete GPUs.
  • _UINavigationControllerPaletteClippingView is now included in the list of system views and windows, hidden in Canvas by default.
    • As always, you can toggle them using CanvasDisplay System Windows and Views menu or the corresponding button on the Canvas.
  • Reveal is now smarter about marking views as “too large” in the Canvas. Size limit has also been raised for apps running in the Simulator.
    • As a result of this change, if your app’s view hierarchy contains large views, you should see Reveal refusing to load their bitmaps less often.
  • Horizontal and vertical stack views now have different icons in the Outline view, making it easier to tell them apart.
  • Inspectors now validate manually entered values for certain attributes (specifically NSLayoutConstraint.priority) and prevent setting values outside of normal range for those attributes.
  • Minimum width of Reveal’s windows has been decreased from 1200 to 1080 points to allow use on narrow displays.

Bugs fixed

  • Fixed a crash occurring on MacBook Pro computers with a Touch Bar when a document is closed while a selection is active.
  • Fixed CALayer.maskedCorners attribute not being editable.

Minimum System Requirements

  • macOS 10.12
  • iOS 8
  • tvOS 9
  • Xcode 8.0
