Lythe

Testing iOS builds

Upload an .ipa and simulate personas against an iOS build.

Fraser can run personas against an iOS build by uploading an application package (.ipa file), the same way it runs against an Android APK.

iOS support is in beta. Availability and behavior may change. If you need it for a specific build, contact sales.

You may only upload builds you own, operate, or are expressly authorized to test. Do not upload malicious, unlawful, or third-party apps. Lythe may scan, restrict, reject, or remove uploaded files to protect the Services, users, or third parties.

When to use it#

iOS testing suits the same questions as web and Android flows, onboarding friction, unclear state, accessibility barriers, but for an iPhone or iPad build, where the constraints are tighter: smaller targets, less room for explanation, and users who are typically more distracted.

Preparing a build#

  • Export an .ipa that reaches the flow you care about without requiring credentials the persona can't have. If the flow is behind auth, supply a test account.
  • Prefer a build close to what ships. Debug builds with placeholder data produce findings about the placeholder data.
  • A TestFlight-style build works well: it's close to production and already stripped of local-only shortcuts.

Persona selection on mobile#

Mobile amplifies impatience and accessibility issues. A sensible default:

  • Impatient multitasker: mobile users are rarely giving you full attention.
  • VoiceOver user: touch targets and labels break more often on mobile, and VoiceOver surfaces them fast.

What to expect in findings#

Findings map to screens and steps within the app, the same shape as web and Android:

Finding:  Sign-in sheet traps focus on iOS
Detail:   After the sign-in sheet opens, VoiceOver focus stays behind it,
          so the persona can't reach the email field without dismissing
          and reopening the sheet.
Fix:      Move focus into the sheet on present, and trap it there until
          the sheet is dismissed.

Limits#

Simulation against a build is an evaluation aid, not a device-lab substitute. It won't replace real-device performance testing, crash reporting, or App Store review.

Running automated simulations against iOS builds may implicate Apple's Developer Program License Agreement and TestFlight terms (TestFlight builds are intended for invited human beta testers). Make sure your use complies with Apple's terms for the build you upload.
