Summary of Changes

This PR consolidates several view extensions from AuthenticatorShared and BitwardenShared into BitwardenKit:

1. NavigationBarViewModifier - Moved to BitwardenKit with public extension
2. View+Toolbar - Moved and enhanced with iOS 26 adaptations
3. navStackWrapped - Moved to BitwardenKit as a public computed property

Net Effect: -229 / +65 lines (good consolidation reducing duplication)

Critical Issues

1. ⚠️ Breaking Behavior Change in cancelToolbarButton

Location: BitwardenKit/UI/Platform/Application/Extensions/View+Toolbar.swift:29-39

The new implementation changes behavior significantly:

Before (AuthenticatorShared):

func cancelToolbarButton(action: @escaping () -> Void) -> some View {
    toolbarButton(asset: SharedAsset.Icons.close16, label: Localizations.cancel, action: action)
        .accessibilityIdentifier("CancelButton")
}

After (BitwardenKit):

func cancelToolbarButton(hidden: Bool = false, action: @escaping () -> Void) -> some View {
    if #available(iOS 26, *) {
        return Button(role: .cancel, action: action)  // System-styled button
            .hidden(hidden)
            .accessibilityIdentifier("CancelButton")
            .accessibilityLabel(Localizations.cancel)
    }
    return toolbarButton(Localizations.cancel, action: action)  // Text button instead of icon
        .hidden(hidden)
        .accessibilityIdentifier("CancelButton")
}

Problems:

• Visual inconsistency: The original used an icon (SharedAsset.Icons.close16), but the new version uses text label on iOS <26
• iOS 26 behavior: System roles may render differently than custom styled buttons, potentially breaking UI consistency
• Authenticator impact: Since AuthenticatorShared code was deleted, any views using this button will see visual changes

Usage sites affected (found 7+ usages):

• GeneratorView.swift:48
• AddEditSendItemView.swift:51
• SetMasterPasswordView.swift:98
• TwoFactorAuthView.swift:51
• VaultUnlockView.swift:42
• And others...

Recommendation: Either:

1. Keep the original icon-based implementation for consistency, OR
2. Document this as an intentional visual change in the PR description, OR
3. Add a migration period where both styles are available

2. ⚠️ Similar Issue with closeToolbarButton

Location: BitwardenKit/UI/Platform/Application/Extensions/View+Toolbar.swift:46-54

Same problem as above - changed from icon-based to system role button on iOS 26.

Usage sites affected (found 5+ usages):

• PasswordHistoryListView.swift:34
• ProfileSwitcherSheet.swift:25
• ImportLoginsSuccessView.swift:57
• ViewItemView.swift:65
• And others...

3. ❌ Missing Public Initializer Documentation

Location: BitwardenKit/UI/Platform/Application/Appearance/Modifiers/NavigationBarViewModifier.swift:16-27

The NavigationBarViewModifier struct is now public but the initializer lacks a DocC comment:

public init(title: String, navigationBarTitleDisplayMode: NavigationBarItem.TitleDisplayMode) {
    self.title = title
    self.navigationBarTitleDisplayMode = navigationBarTitleDisplayMode
}

Per CLAUDE.md: "Everything in the code requires DocC documentation"

Recommendation: Add DocC comment to the public initializer.

Suggested Improvements

4. 🎨 Inconsistent Access Control on toolbarButton(asset:label:action:)

Location: BitwardenKit/UI/Platform/Application/Extensions/View+Toolbar.swift:131

This helper function is used by addToolbarButton but doesn't have explicit access control:

func toolbarButton(asset: SharedImageAsset, label: String, action: @escaping () -> Void) -> some View {

Recommendation: Since this is in a public extension, clarify whether this should be public or keep it internal. The pattern elsewhere in the file shows other toolbarButton variants are public, so this should likely be too.

5. 🎨 Missing Tests for Moved Code

Search Results: No test files found for:

• NavigationBarViewModifierTests.swift
• View+ToolbarTests.swift

While the functionality is likely covered by snapshot tests (48+ files reference these extensions), there are no unit tests specifically for these extensions after the move.

Recommendation: Consider adding unit tests for the toolbar button helpers, especially given the new iOS 26 behavior branches.

6. 📝 Type Alias Inconsistency

Location: BitwardenKit/UI/Platform/Application/Extensions/View+Toolbar.swift:131

Changed from ImageAsset to SharedImageAsset - this is correct, but worth documenting:

Before (BitwardenShared):

func toolbarButton(asset: ImageAsset, label: String, action: @escaping () -> Void)

After (BitwardenKit):

func toolbarButton(asset: SharedImageAsset, label: String, action: @escaping () -> Void)

This change is correct since BitwardenKit uses BitwardenResources.SharedImageAsset, but it's a subtle API change.

7. 🎨 navStackWrapped Duplication Removed Well

The removal of duplicate navStackWrapped implementations from:

• AuthenticatorShared/UI/Platform/Application/Extensions/View.swift
• BitwardenShared/UI/Vault/VaultItemCoordinator.swift (weird location!)

And consolidation to BitwardenKit/UI/Platform/Application/Extensions/View.swift is excellent cleanup. The VaultItemCoordinator location was particularly odd.

Good Practices Observed

✅ Proper use of public access control for BitwardenKit APIs
✅ Consistent DocC documentation on most public APIs
✅ Good consolidation reducing code duplication (229 deletions!)
✅ Maintained backward compatibility for existing call sites
✅ iOS 26 forward-compatibility considerations

Action Items for Author

1. CRITICAL: Review and address the cancelToolbarButton and closeToolbarButton behavior changes:

   • Verify the visual change from icon to text label is intentional
   • Test on iOS 26 to ensure system button roles look acceptable
   • Consider whether AuthenticatorShared views need migration

2. REQUIRED: Add DocC comment to NavigationBarViewModifier.init (line 24)

3. RECOMMENDED: Clarify access control on toolbarButton(asset:label:action:) (line 131)

4. OPTIONAL: Add unit tests for the new iOS 26 conditional logic in toolbar buttons

5. VERIFICATION: Build and run both Bitwarden Password Manager and Authenticator apps to verify no visual regressions

Architecture Compliance

✅ Follows target structure (BitwardenKit for shared components)
✅ Proper dependency injection not applicable (view extensions)
⚠️ Documentation requirement partially met (missing init DocC)
✅ Consistent with existing patterns
