Where Are iPhone Crash Logs Stored?
iPhone crash logs live in Analytics data on the phone and sync to a CrashReporter folder on a paired Mac. Developers symbolicate them there.
Last updated
Every app crash on iPhone writes a small ips log into the phone's analytics store. Users browse them under Settings, Privacy and Security, Analytics data. Pairing with a Mac pulls copies into a CrashReporter folder in Library Logs, sorted per device, which is where developers expect to find them.
Logs rotate, so fetch promptly after a reproducible crash. For beta feedback, the share sheet on the phone beats screenshots of log text. Testers should note the exact timestamp so developers match the right file among dozens.
Where iOS stores this, by platform
Settings > Privacy & Security > Analytics & Improvements > Analytics Data
On device analytics store with one ips file per crash. Share entries directly from Settings when no computer is available. Names carry timestamps for matching.
~/Library/Logs/CrashReporter/MobileDevice
Synced copies from paired devices, one subfolder per phone. Open them in Xcode for symbolication with the matching build.
Frequently asked questions
How do I get a crash log without a computer?
Open Settings, Privacy and Security, Analytics and Improvements, Analytics Data, then tap an entry and share it. Timestamps in the names identify the right log. This is the path when no Mac is handy.
How do developers read these logs?
Open the log in Xcode's Devices window or feed it to the symbolication tool with the matching app binary and dSYM. Unsymbolicated logs show bare addresses, which help nobody.
