Anyone experiencing very slow performance on updating storyboard in Xcode 9? I tested even in brand new project, opening an empty storyboard takes time. Dragging a new UIView or UIButton to existing view in storyboard is so painfully slow. This is on Xcode 9 App Store release, haven't tried on Xcode 9.1 Beta.
Apple .. please fix this, this is so time consuming. If I don't have to support iPhone X, I would have gone back to Xcode 8.
