SwiftDemangler

This module provides support for demangling mangled Swift symbols. Supported mangled symbols begin with $S, $s, _$S", _$s, or _T.

The demangler currently relies on making direct calls to the native Swift demangler tool, which comes bundled with Swift. For example:

% swift demangle --compact --expand _\$s7SwiftUI4ViewMp
Demangling for _$s7SwiftUI4ViewMp
kind=Global
  kind=ProtocolDescriptor
    kind=Type
      kind=Protocol
        kind=Module, text="SwiftUI"
        kind=Identifier, text="View"
protocol descriptor for SwiftUI.View

The resulting tree is parsed by the Ghidra Swift Demangler to form and apply a demangled symbol name.

The Demangler Swift Analyzer looks for the path to the native Swift Demangler binary in the GHIDRA_SWIFT_DEMANGLER environment variable. If that environment variable is not set, the following paths will be tried on non-Windows platforms:

• /usr/bin/swift-demangle
• /usr/bin/swift
