UIBarButtonItems do not respect tintColor property set on a UINavigationItem

In iOS and iPadOS 26 beta 9 (and previous batas), setting the tintColor property on a navigation bar does not tint bar button items. The text and images are always black in the following cases:

• Buttons displaying only text (initWithTitle:)
• Buttons displaying only a symbol (initWithImage:)
• Buttons displaying system items, ie., UIBarButtonSystemItemCancel.
• Nav bar title

The tintColor seems to be respected for:

• Selected-state background for buttons configured with changesSelectionAsPrimaryAction.

To reproduce,

1. Create a UINavigationController,
2. Add bar button items to its navigation item,
3. Set a tint color as in the following statement:

self.navigationController.navigationBar.tintColor = [UIColor redColor];

Then note that the bar button items are black rather than red as expected.
