Classification: | Bug | Reproducible: | true |
With UIKit version shipped with Xcode 12.0 (12A7209), calling `UINavigationController.popToViewController(vc, animated: true)` results in the `viewControllers` property containing unexpected controllers. Specifically, if the starting stack has controller [a, b, c, d] `.popToController(b, animated: true)` would result in the incorrect controller stack after the animation. Expected result: `.viewControllers` property contains [a, b] Actual result: `.viewControllers` property contains [d, a, b] It’s weird. This problem was discovered and discussed here https://developer.apple.com/forums/thread/656524 In that thread it’s supposed to have been reported as FB8626373 as well. Consider this report a duplicate if that’s the case.
