axe DevTools Mobile for iOS

axeDevToolsUIKit.xcframework

Views built with SwiftUI cannot be tested using this framework

Use the axeDevToolsXCUI framework in UITesting for SwiftUI views.

Custom rule support is available only in Swift

The custom rule API is not open to Objective-C.

The "Visible to User" filter may not work properly on side menus and alerts.

We are actively working on a fix and are expecting it in the next release.

False Positives: CollidingViews, InScrollView, SupportsDynamicType, InaccessibleAction

We are actively working on fixes for the following false positives and will update this list as fixes are released.

CollidingViews
Currently, the CollidingViews rule utilizes the size of the UILabel frame. When the frame is larger than the visible text, it may incorrectly flag text as colliding with another element on the screen.

InScrollView
InScrollView may report issues for text within banner-behaving elements. To make these elements available to those that require larger text, use UILargeContentViewer.

SupportsDynamicType
You may see false positives in the following scenarios:

  • If using the UIContentSizeCategoryDidChange notification, the framework may incorrectly report that text does not respond to Dynamic Type in UITests.
  • If using NotificationCenter.default.addObserver(forName:.., object:.., queue:.., using:..) to respond to the UIContentSizeCategoryDidChange notification.
  • If using traitCollectionDidChange on a text's parent view or view controller to respond to Dynamic Type.

axeDevToolsXCUI.xcframework

SwiftUI Picker and UIKit Picker

Picker views in SwiftUI and UIKit may cause the framework to get stuck on simulators or devices.

The "Visible to User" filter may not work properly on side menus and alerts.

We are actively working on a fix and are expecting it in the next release.

Landscape orientation is not formally supported at this time

This will be addressed in a later version.

False Positives: A11yElementFocusBox, CollidingViews, InScrollView, LabelAtFront (iOS 16)

We are actively working on fixes for the following false positives and will update this list as fixes are released.

A11yElementFocusBox
For views that are off-screen, this rule may incorrectly report the VoiceOver focus box is not encapsulating the view.

CollidingViews
Currently, the CollidingViews rule utilizes the size of the UILabel frame. When the frame is larger than the visible text, it may incorrectly flag text as colliding with another element on the screen.

InScrollView
InScrollView may report issues for text within banner-behaving elements. To make these elements available to those that require larger text, use UILargeContentViewer.

LabelAtFront
Effects iOS 16+. Results for LabelAtFront may not be correct on picker elements.
