App Store 2.5.6 rejection: WebKit and alternative browser engines

An embedded browser can bring its own review requirements. Under 2.5.6, apps browsing the web generally need the appropriate WebKit technologies. Apple offers alternative-engine entitlements under specific regional conditions, including documented arrangements for the EU and Japan.

Identify the engine you ship

Ask your developer which component renders pages and executes web JavaScript. Check bundled browser libraries and region-dependent builds. We’d distinguish a standard system web view from a custom engine before changing the app.

Match the implementation to your approval

Use Apple’s supported WebKit approach unless the app has the appropriate alternative-engine entitlement and meets its conditions. Applying for an entitlement isn’t the same as having permission to ship it. Consult the linked Apple entitlement documentation for supported regions and obligations.

Test browsing, authentication, and opening external links in the corrected build. Give Apple the engine used and any applicable entitlement evidence. Explain regional behavior explicitly so the reviewer can test the version they receive.
