+Title: Keeping the Lyft iOS App Accessible
+Date: 2017-01-18
+Summary: Explanation on some strategies in how Lyft keeps its iOS app accessible
+
+!!! note
+    This article was written by me but originally published on the [Lyft
+    Engineering Blog](https://eng.lyft.com/keeping-lyft-accessible-53155f0098b9).
+
+At Lyft we’re in a unique position: every day we work on an app that affects
+people in the real, physical world — not just the digital one. This has an
+especially large impact on visually impaired users, because our app is
+easier to use than the real world alternatives — navigating a train station
+or queueing up at a taxi stand. Lyft aims to make a product that is
+accessible and easy to use for all of our users.
+
+## Accessibility at Lyft
+
+If an app uses Apple’s standard controls and UI elements, it will likely already
+work well with VoiceOver; however, Lyft’s UI deviates enough from standard
+controls such that we don’t get that benefit out of the box. Another
+complication is that many portions of the app are controlled by the server,
+including a lot of the text for buttons and labels. Making these UI elements
+compatible with VoiceOver often requires tweaking them manually, even if we use
+native controls.
+
+Since we try to keep all of our UI-related code in Interface Builder, and
+VoiceOver is just another form of UI, we have written a simple `UIView`
+extension that allows us to enable accessibility on most of our UI directly from
+Interface Builder. In this extension, we add 2 properties to `UIView`:
+
+* `accessibilitySources`: An `IBOutletCollection` of `UIView`s
+* `accessibilityFormat`: a simple string that represents the format of the
+  accessibility label, which is subsequently passed to `String(format:)`. Every
+  occurrence of `%@` in this string will be replaced with the next element of
+  the `accessibilitySources`, and `[self]` will automatically be replaced with
+  the current view’s accessibilityLabel.
+
+We can ctrl + drag UI elements into the `accessibilitySources`, and by marking
+`accessibilityFormat` with `@IBInspectable` we can specify the string and the
+sources all from Interface Builder, keeping the code clean and to the point.
+
+For example, we have an accessibility format on the UILabel that displays the
+selected ride mode:
+
+![Setting the accessibility format](/images/AccessibilityFormat.png)
+
+`[self]` is replaced by the accessibility label, which for `UILabel`s is the
+text of the label itself. `%@` is replaced by an accessibility source, which we
+can set up like this:
+
+![Setting the accessibility sources](/images/AccessibilitySource.png)
+
+By disabling the accessibility label for the subtitle, the top label’s
+accessibility label will read “Selected ride mode: Line. Carpool, 2 people
+maximum.” without touching any code at all.
+
+## Changing the process
+
+As we ramped up our VoiceOver efforts, we wanted to assess whether the changes
+we made had a meaningful impact to end-users. As developers, we’re too familiar
+with our own apps to make an honest call about their usability, and when it
+comes to visual impairment, even a standard usability review could brush over
+things that would be challenging to a blind or a visually impaired user.
+
+This is why we’re working with a dedicated accessibility expert, himself a
+native VoiceOver user, to constantly validate our work. All the feedback we’ve
+been getting from VoiceOver users have further motivated our investment in
+accessibility. We have optimized VoiceOver in the main flows of our app, and we
+run weekly regression tests to ensure consistency and stability. Our VoiceOver
+user also works directly with QA engineers, to let them know what he is looking
+for and what is missing.
+
+Over the last few months, we have made many improvements in various parts of our
+app, but also in how seriously we take VoiceOver-related bugs: we block new
+releases if VoiceOver users experience bugs when going through a ride. All new
+features are expected to be optimized for VoiceOver from the start, and we are
+working hard to optimize existing features as well.
+
+We think of accessibility as part of the user interface, just like labels,
+buttons, and text fields. By having our developers implement support for
+VoiceOver as part of the initial feature, our visually impaired users will be
+able to use these features as easily as our regular users.
