fix(explore-dash): stop per-foreground IP geolocation lookup#1055QuantumExplorer wants to merge 1 commit into

checkGeoRestriction is invoked from applicationDidBecomeActive, and checkRestriction unconditionally issued a request to ip-api.com. That disclosed the user's IP address and an app-open timestamp to a third-party geolocation service on every foreground, to decide whether to hide one gift-card provider. PIGGYCARDS_ENABLED is set in Release and Testflight, so this shipped. Nothing throttled it: hasCheckedRestriction was assigned but never read. The request also went out even when GPS had already resolved the country and would win the priority check, because all sources were awaited up front. Country detection now uses on-device sources only, in the order GPS -> App Store storefront -> device region. Guard on hasCheckedRestriction so the work happens once per launch; leave the flag false when nothing resolves so a later call retries. Live GPS updates still refresh the status via setupLocationObserver. Also fixes the App Store branch, which could never match: StoreKit's Storefront.countryCode is ISO 3166-1 alpha-3 (init(iso3ACountryCode:)), while restrictedCountryCodes held alpha-2, so a Russian user without location permission got "RUS" and was silently treated as unrestricted. The set now carries both forms. Drops the DetectionSource.ipGeolocation case, which nothing can produce any more, and the per-invocation debug logging.

📝 WalkthroughWalkthroughChangesGeo-restriction detection
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to The change removes network-based geolocation, but a storefront change after the initial check may leave the country restriction status stale until another forced check or relaunch. This is a bounded correctness risk that needs owner awareness and follow-up before merging. Suggested reviewers: Sequence Diagram(s)sequenceDiagram

Apple StoreKit Storefront.updates behavior countryCode changes documentation
💡 Result:
In StoreKit 2, the Storefront.updates asynchronous sequence is the recommended mechanism for listening to changes in the App Store storefront, including updates to the countryCode [1][2][3]. Key points regarding its behavior include: Official Documentation: The Storefront.updates property is an asynchronous sequence that emits Storefront information whenever the system updates the storefront [4][2]. Apple advises that because the storefront value can change at any time, apps should monitor this sequence and respond to changes (e.g., by refreshing the list of available products) [1][2]. Usage: You should listen to this sequence to detect when a user changes their App Store region or switches Apple ID accounts [5][6]. When a change is emitted, you can access the updated countryCode from the emitted Storefront object [5][7]. Known Limitations and Issues: - Sandbox Testing: In the sandbox environment, switching accounts can sometimes fail to trigger updates or result in stale countryCode values due to caching or system-level bugs [8][9]. Developers have reported scenarios, particularly in certain iOS 18.x versions, where countryCode does not synchronize after switching sandbox accounts in settings [8]. - Best Practices: If you encounter issues with stale values, ensure you are fully signed out of the previous Apple ID in the system settings and signed into the new one [9]. In production, the API is generally reliable, but developers should always build their apps to handle storefront changes dynamically by reacting to Storefront.updates rather than caching the storefront value indefinitely [2][10]. Legacy APIs: The SKStorefrontCountryCodeDidChangeNotification (used with the older StoreKit 1 SKPaymentQueue) is considered deprecated in favor of using Storefront.updates [3]. Top results: [4], [8], [2], [10]

Subscribe to App Store storefront changes.
When storefront resolution sets hasCheckedRestriction, later checks do not re-read Storefront.current. Observe Storefront.updates and update the restriction status for each new countryCode. Add coverage for a storefront-only resolution followed by a storefront change.

What
GeoRestrictionServiceno longer contactsip-api.com. Country detection now uses only on-device sources: GPS → App Store storefront → device region.This also fixes a latent bug that made the App Store branch dead code, and stops the check from re-running on every foreground.
Why
This came out of a community question in the Russian Telegram group asking whether analytics/tracking are enabled in the new iOS build. There is no analytics SDK in the iOS app — no FirebaseAnalytics, GoogleAppMeasurement, Crashlytics, Mixpanel, Amplitude, Sentry or AppsFlyer is linked, there are zero
logEvent/trackEventcall sites, and there is no IDFA/ATT surface. But the audit did turn up outbound calls, and this was the most significant one.ExploreDashObjcWrapper.checkGeoRestrictionis invoked fromapplicationDidBecomeActive(DashWallet/AppDelegate.m), andcheckRestriction()unconditionally issued:That disclosed the user's real IP address, plus an app-open timestamp, to a third-party geolocation service every time the wallet was foregrounded.
PIGGYCARDS_ENABLEDis set in the Release and Testflight configurations, so this shipped.Three things made it worse than it needed to be:
hasCheckedRestrictionwas assigned inupdateRestrictionStatusbut never read, so nothing gated re-entry — every foreground repeated the request.gpsCountry,ipCountryandappStoreCountrywere all awaited before the priority check, so the IP request went out even when GPS had already resolved the country and would win.The latent alpha-2 / alpha-3 bug
Worth calling out separately, because this PR promotes the App Store storefront from third choice to second.
restrictedCountryCodesheld["RU", "CU"]— ISO 3166-1 alpha-2. But StoreKit'sStorefront.countryCodereturns alpha-3; the SDK's own initialiser isinit(iso3ACountryCode:id:locale:)andSKStorefront.hdocuments it as "The three letter country code for the current storefront". So the App Store branch could never match: a user in Russia with location permission denied got"RUS", which was not in the set, and was silently treated as unrestricted.CoreLocation's
isoCountryCodeandLocale.Region.identifierare alpha-2. Rather than convert, the set now lists both forms and documents why:Behaviour change
"RUS"/"CUB"storefrontDevice region (
Locale.current.region) replaces IP as the last resort so a signal still exists when GPS is unauthorised and StoreKit returns nothing. If nothing resolves, the behaviour is unchanged — unrestricted — andhasCheckedRestrictionis deliberately leftfalseso a later call retries.Live GPS updates still refresh the status through
setupLocationObserver, andrefreshRestriction()still forces a re-check.The
DetectionSource.ipGeolocationcase is removed since nothing can produce it. A previously persisted"IP Geolocation"string now decodes tonil; that property is diagnostic only and has no consumers outside this file.Also removed
The
🌍-prefixed debug logging (roughly 15 lines per invocation, per foreground), replaced with one line stating the outcome — per the "no debug residue in commits" guardrail inCLAUDE.md. Two stale comments at the call sites that described the old log-every-foreground behaviour are updated.Verification
GeoRestrictionService.swiftandExploreDash.swiftcompile clean.Full disclosure on the build:
xcodebuild -scheme dashpaydoes not currently reach a successful link in my environment, but the failure is pre-existing ondevelopand unrelated to this change. It is four errors inEvonodeStatusViewModel.swift(value of type 'SDK' has no member 'getEvonodeStatus',cannot find type 'EvonodeStatus' in scope,'PlatformMasternode' has no member 'platformDAPIAddress') caused by the local../platformSwiftDashSDK checkout sitting on an unrelated feature branch that predates that API. I confirmed this by stashing this PR's changes and rebuilding untoucheddevelop, which produces the identical four errors. No error references any file this PR touches.Related
Two companion PRs address the other outbound channels found in the same audit: #1053 disables the Firebase diagnostics heartbeat, and a third removes the unused Firebase Dynamic Links SDK, which fingerprints the device on first launch.
