Crashes don’t end when the app terminates.
They begin after.
Most teams fail not because crashes happen —
but because they don’t know:
- which crashes matter
- who is affected
- what changed
- how urgent it is
- what to fix first
Crash reporting is not a tool.
It is an incident response system.
This post shows how to design crash reporting & triage architecture for SwiftUI apps that turns crashes into actionable decisions, not panic.
🧠 The Core Principle
A crash without context is noise.
Your job is not to collect crashes —
it is to prioritize incidents.
🧱 1. Crash Reporting Is a Pipeline
Think in stages:
Crash
→ Capture
→ Enrich
→ Group
→ Prioritize
→ Fix
→ Verify
Tools only handle capture.
Architecture handles the rest.
📦 2. Crash Reporter Lives in Infrastructure
Crash reporting must live:
- in AppContainer
- next to logging & analytics
- initialized as early as possible
Never initialize crash SDKs in views.
🧭 3. Enrich Every Crash Automatically
A raw stack trace is useless alone.
Attach context:
- app version
- build number
- feature flags
- experiment variants
- config version
- device class
- OS version
- memory state (if available)
Example enrichment:
crashReporter.setContext([
"app_version": version,
"flags": flags.snapshot(),
"experiments": experiments.snapshot()
])
Context turns crashes into clues.
🧠 4. Crash Grouping Strategy
Not all crashes are equal.
Group by:
- exception type
- top stack frames
- feature ownership
- recent releases
Avoid grouping solely by stack trace hash —
minor line shifts create fake “new” crashes.
🚨 5. Severity Scoring
Define severity explicitly:
| Level | Description |
|---|---|
| P0 | App launch crash |
| P1 | Data loss / corruption |
| P2 | Feature blocked |
| P3 | Edge-case crash |
| P4 | Cosmetic / rare |
Severity is architecture, not emotion.
🧬 6. Release-Aware Crash Triage
Every crash must answer:
- did this appear in the latest release?
- did crash rate spike?
- which change introduced it?
If your crash tooling can’t correlate crashes to releases, you are blind.
🧪 7. Reproducibility Is the Goal
Good crash reports allow you to:
- reproduce locally
- identify feature boundary
- isolate state
- write a regression test
If you can’t reproduce it, you can’t fix it reliably.
⚠️ 8. Avoid Over-Reporting
Not every error should crash.
Rules:
- never crash on network failure
- never crash on invalid input
- never crash on server bugs
- crash only on corrupted invariants
Example:
assertionFailure("Invalid state")
in debug
→ graceful recovery in release
🔐 9. Privacy & Crash Reporting
Never attach:
- emails
- names
- tokens
- payloads
- PII
Crash reports must be:
- anonymized
- scrubbed
- compliant by default
A useful crash report is still a data leak if done wrong.
❌ 10. Common Crash Triage Anti-Patterns
Avoid:
- chasing every crash equally
- fixing without reproduction
- ignoring crash rate trends
- silencing crashes blindly
- shipping hotfixes without verification
- blaming “SwiftUI bugs”
Most crashes are architectural, not framework bugs.
🧠 Mental Model
Think:
Crash
→ Context
→ Impact
→ Priority
→ Fix
→ Verification
Not:
“Oh no, another crash”
🚀 Final Thoughts
A real crash architecture gives you:
- calm incident response
- focused fixes
- fewer regressions
- faster recovery
- trust in production
Crashes will happen.
Chaos is optional.
