objective-c uistackview autolayout Objective-C

I'm prototyping a solution and Hey everyone, I'm running into an issue that's driving me crazy... I'm experiencing unexpected behavior when dynamically adding and removing views from a `UIStackView`. My intention is to show a list of items, and when the user selects an item, I want to replace the item with a detail view. However, after removing one of the arranged subviews and adding a new one, the layout doesn't update as expected. It seems like the stack view is not recalculating its layout correctly, and sometimes the removed views reappear. Here’s a simplified version of my code: ```objective-c self.stackView.axis = UILayoutConstraintAxisVertical; self.stackView.spacing = 10; - (void)updateViewForSelectedItem:(UIView *)item { [self.stackView removeArrangedSubview:item]; [item removeFromSuperview]; UIView *detailView = [[UIView alloc] init]; detailView.backgroundColor = [UIColor blueColor]; [self.stackView addArrangedSubview:detailView]; [self.stackView layoutIfNeeded]; } ``` I’ve tried calling `layoutIfNeeded` on the stack view after adding the new view, but it doesn't seem to help. I also tried setting `translatesAutoresizingMaskIntoConstraints` to `NO` for the `detailView`, but that didn't change the outcome. I'm using Xcode 14.0 and deploying to iOS 16.0. Any insights on what might be causing this scenario or best practices on managing views in a `UIStackView` would be greatly appreciated. My development environment is Ubuntu. For reference, this is a production mobile app. Am I approaching this the right way?
