Merge Risk: 🟠 High · up to a6ab8

The new crash-reporting module does not compile as written, so the app cannot be built until the missing import is added. Once it builds, the app can crash at launch if saved or bundled data fails to decode, because the reporter is registered too late. A shipped build would also expose the Discord webhook token to anyone who inspects the app. Crash reports may show misleading file and line context. These issues should be fixed before merging.

Security Architecture Review

Security architecture risk: 🟠 High · up to a6ab8

A configured Discord webhook URL would be packaged with the app and could be used outside the app to post to its reporting channel. Error descriptions also cross into Discord without an observed redaction boundary. The actual contents of production errors and release configuration remain unverified.

Retained concerns

  • High · security · observed: The new app plist entry packages the configured Discord webhook URL for use as a posting credential. Someone who obtains it from a distributed app can post independently of the app’s reporting controls; the supported scope is the configured webhook and channel.
  • Medium · security · observed: The shared reporter forwards up to 1,024 characters of a generic error description to Discord without an observed data-classification or redaction step. Some upstream errors include an underlying error description, but sensitive production content reaching this path is not established.
  • Low · security · inferred: The shared reporter checks and updates its webhook timestamp without synchronization. Concurrent error callbacks can pass the same five-second admission check, so the client-side limit is not a reliable bound on report volume or exported error text.
Security review details

Security Blast Radius

  • inferred — Each distributed build containing a working webhook URL exposes the ability to address that webhook outside app-controlled throttling. The independently supported affected asset is its Discord reporting channel, not the app’s other stored credentials or Firebase project.

Security Findings and Attack Paths

  • observed — The retained webhook finding is supported by the new plist entry and the reporter’s use of that value as its request destination. The separate error-content candidate remains deferred: upstream descriptions can propagate, but sensitive runtime contents were not verified.

Trust Boundaries and Controls

  • observed — Repository errors cross from app and network operations into Crashlytics and, when configured, Discord. The Discord path checks URL presence and applies a five-second client-side interval, but neither check authenticates an independent holder of the webhook URL or filters the error description.

Resilience and Maintainability Implications

  • inferred — Independent asynchronous error callbacks can overlap at the unsynchronized timestamp check. Sequential calls are throttled, and a webhook failure does not prevent the earlier Crashlytics record; neither fact makes the Discord admission transition atomic.

Hardening Proposals

  • proposed — Keep the Discord posting credential outside the distributed client, and define an allowlisted error payload before exporting diagnostics. If webhook volume is a security control, enforce its limit at a trusted endpoint rather than relying on the client timestamp.

Inline comments:
In `@Projects/App/Sources/AppDelegate`+Firebase.swift:
- Line 27: Update the error-reporting path in configureFirebase so failures
before FirebaseApp.configure(options:) do not rely on Crashlytics; use an
independent diagnostic mechanism when FirebaseOptions(contentsOfFile:) returns
nil, while preserving Crashlytics reporting for errors after initialization.

In `@Projects/App/Sources/AppDelegate`+Register.swift:
- Line 48: Move the CrashReporter registration in the AppDelegate registration
flow before the repository registrations, including FavoritesRepository,
BusStopArrivalInfoRepository, and StationListRepository, so repositories can
resolve it during initialization.

In `@Projects/FirebaseModule/Sources/CrashReporterImpl.swift`:
- Around line 25-26: Update reportFatal in the CrashReporter implementation so
errors handled by this method are reported as non-fatal, matching Crashlytics’
record(error:) classification and the Discord display. Leave actual app crashes
to Crashlytics automatic collection.
- Line 5: CrashReporterImpl이 상속하는 CrashReporter를 찾을 수 있도록 이 파일에
FirebaseInterface 모듈을 import하세요.
- Around line 35-36: Replace the global `setCustomValue` calls for `file` and
`line` with error-specific metadata passed through `record(error:userInfo:)`, so
each crash report retains the source context for its own error.
- Around line 54-55: Serialize the report-interval check and `lastReportTime`
update in `CrashReporterImpl` so concurrent error callbacks cannot both pass the
check or race on the shared date; keep the check and update in the same
synchronized section.

In `@Scripts/fix_deployment_target.sh`:
- Line 4: Update the script flow around `tuist generate` so a generation failure
stops execution and propagates its nonzero exit status instead of reaching the
completion message; use fail-fast behavior or chain the subsequent commands to
it.

In `@Tuist/ProjectDescriptionHelpers/InfoPlist/SecretInfoPlist.swift`:
- Line 18: Remove DISCORD_WEBHOOK_URL from SecretInfoPlist so the webhook URL
and token are not bundled in the app; route Discord webhook requests through a
server instead, and rotate any token already included in a distributed build.

<title>Cannot get new Crashlytics instance after deleting and recreating default FirebaseApp · Issue `#14220` · firebase/firebase-ios-sdk</title>
<location>GitHub issue 14220 in firebase/firebase-ios-sdk (link omitted to avoid creating a cross-reference)</location>
<excerpt>## Cannot get new Crashlytics instance after deleting and recreating default FirebaseApp ... We need to change default firebase app configuration at some point in our application, and want to get a Crashlytics instance for this new default app (which has a different configuration than the previous one). ... So we start by deleting current default application doing `FirebaseApp.app()?.delete()`. ... Looking at code it should clear the associated container that keeps the Crashlytics cached instance: ... But after configuring the new default app with custom configuration using `FirebaseApp.configure(options: newOptions)` we cannot get the associated new Crashlytics instance. We have this error message instead: ... &gt; 11.6.0 - [FirebaseCrashlytics][I-CLS000000] Cannot instantiate more than one instance of Crashlytics. ... ``` if (!atomic_compare_exchange_strong(&amp;_hasInitializedInstance, &amp;expectedCalled, YES)) { FIRCLSErrorLog(@&quot;Cannot instantiate more than one instance of Crashlytics.&quot;); return nil; } ``` ... Meaning that `_hasInitializedInstance` is not resetted to `false` when the first `FirebaseApp` was deleted, and it&`#39`;s container cleared. ... ``` FirebaseApp.configure() Crashlytics.crashlytics().setCrashlyticsCollectionEnabled(true) await FirebaseApp.app()?.delete() FirebaseApp.configure(options: newOptions) // Set new options, maybe the problem occurs with default options too Crashlytics.crashlytics().setCrashlyticsCollectionEnabled(true) // Logs: 11.6.0 - [FirebaseCrashlytics][I-CLS000000] Cannot instantiate more than one instance of Crashlytics. ``` ... ```shell 11.6.0 - [FirebaseCore][I-COR000003] The default Firebase app has not yet been configured.

Per checking, this seems to be an expected behavior. Crashlytics only works on Firebase default app. During initialization, we only register the Crashlytics component to default app (with the name __FIRAPP_DEFAULT).

See the related code [here](https://github.com/firebase/firebase-ios-sdk/blob/main/Crashlytics/Crashlytics/FIRCrashlytics.m#L233). ... &gt; I&`#39`;ve seen that Crashlytics is tied to Firebase default app, but if we delete the Firebase default app Crashlytics shouldn&`#39`;t be stuck. We should be able to get Crashlytics for the newly configured Firebase default app that replaces the previous one, using the same name `__FIRAPP_DEFAULT`. It won&`#39`;t lead to multiple instances of Crashlytics since the previous one has been destroyed when deleting the Firebase app when the cache container was cleaned. Moreover the single instance check could be made on the cache container instead of an external boolean. &gt; &gt; In my code example the second call to `FirebaseApp.configure()` isn&`#39`;t specifying the app name so it will be the new Firebase default app named `__FIRAPP_DEFAULT`. ... …[truncated]</excerpt>

Firebase 초기화 전에는 Crashlytics에 의존하지 않는 경로로 오류를 보고하세요.

FirebaseOptions(contentsOfFile:)가 nil이면 configureFirebase는 FirebaseApp.configure(options:) 전에 오류를 던집니다. 이때 FirebaseCrashlytics 11.4.0의 Crashlytics.crashlytics()는 기본 앱이 없어 nil 인스턴스를 반환합니다. 이후 setCustomValue와 record(error:) 호출은 아무 작업도 하지 않으므로 오류가 Crashlytics에 기록되지 않습니다. 이 오류에는 Firebase 초기화에 의존하지 않는 별도 진단 경로를 사용하세요.

FirebaseApp.configure(options:) do not rely on Crashlytics; use an independent

reportFatal의 Crashlytics 기록 방식을 수정하세요.

reportFatal과 reportNonFatal은 모두 record(error:)를 호출합니다. Firebase는 이 API로 기록한 오류를 non-fatal 이벤트로 분류합니다. 따라서 Discord의 Fatal 표시와 Crashlytics의 분류가 다릅니다. 처리된 오류라면 인터페이스와 Discord 표시를 non-fatal로 맞추고, 실제 앱 비정상 종료는 Crashlytics의 자동 수집에 맡기세요. (firebase.google.com)

26, Update reportFatal in the CrashReporter implementation so errors handled by
this method are reported as non-fatal, matching Crashlytics’ record(error:)
classification and the Discord display. Leave actual app crashes to Crashlytics
automatic collection.

웹훅 전송 간격 상태를 동기화하세요.

여러 요청의 오류 콜백이 동시에 실행되면 두 호출이 같은 lastReportTime을 읽고 모두 전송할 수 있습니다. 공유 Date의 읽기·쓰기에도 데이터 경쟁이 생깁니다. 간격 검사와 갱신을 하나의 직렬 실행 구간으로 묶으세요.

55, Serialize the report-interval check and `lastReportTime` update in
`CrashReporterImpl` so concurrent error callbacks cannot both pass the check or
race on the shared date; keep the check and update in the same synchronized
section.

Discord 웹훅 토큰을 앱의 Info.plist에 넣지 마세요.

배포 빌드에 실제 DISCORD_WEBHOOK_URL을 설정하면 앱을 받은 사람이 Info.plist에서 URL과 실행 토큰을 추출할 수 있습니다. 추출한 토큰으로 앱의 전송 간격 제한을 거치지 않고 웹훅에 메시지를 게시할 수 있습니다. 웹훅 호출을 서버로 옮기고, 이미 배포한 토큰이 있다면 교체하세요. Discord 문서는 웹훅 URL에 토큰이 포함됨을 보여 줍니다. (discord.com)

질문드려요. NonFatal, Fatal 함수를 어떤 상황마다 호출해야할지 기준을 모르겠는데 생각하신 기준이 있으시다면 설명 부탁드립니다!

질문드려요. NonFatal, Fatal 함수를 어떤 상황마다 호출해야할지 기준을 모르겠는데 생각하신 기준이 있으시다면 설명 부탁드립니다!

기능이 정상 동작을 하지 못하는 경우에 Fatal 함수를 호출하고, 기능의 일부가 누락될 경우에 non fatal 이라고 생각했습니다.
