Motivation
DefaultPaywallViewshows configuration warnings only in DEBUG. The RevenueCat mobile app's UI preview mode runs in release configuration, so those warnings never appear for developer, and they may help them debug the issue more easily. This change surfaces them in UI preview mode.Description
@_spi(Internal) Purchases.isUIPreviewModeand threads it throughPaywallPurchasesType/PurchaseHandler.shouldShowWarningreturns true in UI preview mode when a warning exists, even outside DEBUG.Note
Low Risk
UI-only gating for developer warnings with no purchase or auth changes; release behavior unchanged unless UI preview mode is explicitly configured.
Overview
Default paywall configuration warnings now appear in UI preview mode on release builds, not only in DEBUG.
The PR adds
@_spi(Internal) Purchases.isUIPreviewMode(fromDangerousSettings.uiPreviewMode) and threads it throughPaywallPurchasesType,PurchaseHandler, and test/stub implementations (MockPurchases,NotConfiguredPurchases,LoadingPaywallPurchases).DefaultPaywallView.shouldShowWarningstill shows warnings whenever one exists in DEBUG; in release it only shows when both a warning is present andhandler.isUIPreviewModeis true, so production users do not see developer-facing warnings.Reviewed by Cursor Bugbot for commit 2b261a6.
