Greptile Summary

This release (4.15.3) fixes computed subscription period prices (weeklyPrice, dailyPrice) that were off by a small amount for products expressed in days, by replacing the approximate 365/52 day↔week conversion with the exact factor of 7.

• Price calculation fix: SubscriptionPeriod.pricePerDay (.week case) and pricePerWeek (.day case) now use 7 as the exact conversion factor instead of 365/52 ≈ 7.019, which caused a 7-day subscription's weeklyPrice to read e.g. £7.00 instead of £6.99. The same fix is applied inline to APIStoreProduct and StripeProductType.
• SK2 refactor: SK2StoreProduct's four computed-price properties are collapsed into a single formattedComputedPrice helper that delegates to the now-centralized SubscriptionPeriod methods, with normalization (collapsing .day × 7 → .week × 1) applied at the SubscriptionPeriod.from(...) layer.
• Testability: normalized() is widened from private to internal so new unit tests can exercise the normalization path directly.

Confidence Score: 5/5

Safe to merge — the arithmetic fix is narrow, well-reasoned, and backed by new regression tests covering the exact failure cases.

The change replaces an approximate week↔day factor (365/52) with the exact value (7) uniformly across SubscriptionPeriod, APIStoreProduct, and StripeProductType. SK2StoreProduct is also cleaned up by centralising the four price computations into one helper that routes through the normalised SubscriptionPeriod. The new tests pin the before/after values and verify that a 7-day period and a 1-week period produce identical prices. No untested edge cases were identified that weren't already exercised by the existing or new test suite.

No files require special attention.

Important Files Changed

Filename	Overview
Sources/SuperwallKit/StoreKit/Products/StoreProduct/SubscriptionPeriod.swift	Core fix: replaces the approximate 365/52 week↔day factor with the exact value 7 in pricePerDay and pricePerWeek; normalized() is widened to internal for testability. Logic is correct and consistent.
Sources/SuperwallKit/StoreKit/Products/StoreProduct/SK2StoreProduct.swift	Refactors four duplicated price-computation blocks into a single formattedComputedPrice helper that routes through the normalized SubscriptionPeriod; eliminates ~72 lines of inline logic.
Sources/SuperwallKit/StoreKit/Products/StoreProduct/APIStoreProduct.swift	Applies the same day↔week conversion fix inline (not refactored to use SubscriptionPeriod helpers); numerically correct and consistent with the SubscriptionPeriod changes.
Sources/SuperwallKit/StoreKit/Products/StoreProduct/StripeProductType.swift	Applies the same day↔week conversion fix inline for dailyPrice (.week case) and weeklyPrice (.day case); comments explain the rationale.
Tests/SuperwallKitTests/StoreKit/Products/StoreProduct/SubscriptionPeriodPriceTests.swift	Adds targeted regression tests for the day↔week fix, normalization, and consistency between 7-day and 1-week periods. Good coverage of the changed logic.
