iPadOS 15 UITabBar title cut off - ios

Question

Since I upgraded my iPad operating system, the title of the UITabBar of my app is showing truncated, as shown in the screenshot.
I have tried some methods, but I have not found the correct solution.
Hope someone can help me.
And Here is code:
func setupTabBar() {
if #available(iOS 13, *) {
let appearance = tabBar.standardAppearance
appearance.configureWithOpaqueBackground()
appearance.backgroundImage = UIImage(color: .white)
appearance.shadowImage = UIImage(color: .clear)
let normalAttrs: [NSAttributedString.Key: Any] = [.foregroundColor: ThemeColor.gray]
let selectedAttrs: [NSAttributedString.Key: Any] = [.foregroundColor: ThemeColor.red]
appearance.stackedLayoutAppearance.selected.titleTextAttributes = selectedAttrs
appearance.stackedLayoutAppearance.normal.titleTextAttributes = normalAttrs
appearance.inlineLayoutAppearance.selected.titleTextAttributes = selectedAttrs
appearance.inlineLayoutAppearance.normal.titleTextAttributes = normalAttrs
appearance.compactInlineLayoutAppearance.selected.titleTextAttributes = selectedAttrs
appearance.compactInlineLayoutAppearance.normal.titleTextAttributes = normalAttrs
UITabBar.appearance().standardAppearance = appearance
} else {
tabBar.backgroundImage = UIImage(color: .white)
tabBar.shadowImage = UIImage(color: .clear)
}
if #available(iOS 15, *) {
UITabBar.appearance().scrollEdgeAppearance = UITabBar.appearance().standardAppearance
}
}

Answer 1

For some reason, it seems that setting the titleTextAttributes is what causes the problem to happen with inlineLayoutAppearance, and including the default paragraph style of NSParagraphStyle.default fixes it.
For your code, the following changes should fix it (as of iOS 15.0).
let normalAttrs: [NSAttributedString.Key: Any] = [.foregroundColor: ThemeColor.gray, .paragraphStyle: NSParagraphStyle.default]
let selectedAttrs: [NSAttributedString.Key: Any] = [.foregroundColor: ThemeColor.red, .paragraphStyle: NSParagraphStyle.default]

Answer 2

For those that cannot have a default paragraph style, setting the attributes for most States got the OS to size the labels correctly for me.
Swift 5.0:
UITabBarItem.appearance()
.setTitleTextAttributes(
customAttributesWithCustomParagraphStyle,
for: [
.normal,
.highlighted,
.disabled,
.selected,
.focused,
.application,
]
)
Without setting it for at least .normal and .selected, the UITabBarItem title gets truncated when used with custom attributes.
