💥 Backtraces for Swift on Linux and Windows
.package(url: "https://github.com/swift-server/swift-backtrace.git", from: "1.3.1")


This Swift package provides support for automatically printing crash backtraces of Swift programs.


Add https://github.com/swift-server/swift-backtrace.git as a dependency in your Package.swift.

Crash backtraces

In your main.swift, do:

import Backtrace

// Do this first

Finally, for Swift < 5.2, make sure you build your application with debug symbols enabled. Debug symbols are automatically included for Swift 5.2 and above.

$ swift build -c release -Xswiftc -g

When your app crashes, a stacktrace will be printed to stderr.


Please see SECURITY.md for details on the security process.
