I'm trying to set a standard width for my UITabBarButtons by setting the following properties of my UITabBar:
tabBar.itemPositioning = .centered
tabBar.itemWidth = 76.0
tabBar.itemSpacing = 34.0
When running on my physical iPad running iOS 10.1.1 the tab bar items are properly sized, but when running on the iPad pro 10.5 simulator running ios 11, the itemWidth property isn't taken into account.
iPad Pro 10.5 inch running ios 11

I'm building with XCode 9 with a deployment target of ios 9.0.
