swift-pd-guess

Try to guess the file name from private discriminator of a Swift symbol.

Usgae

swift-pd-guess <hash> <words> --prefix <prefix> [--suffix <suffix>] [--max-count <max-count>]

Example

For DemoKit binary, we can see some private symbol have _00D91DAB7748ABA327DC94E69D678CAF in their demangled name.

Eg. _$s7DemoKit3FooV7Private33_00D91DAB7748ABA327DC94E69D678CAFLLVMn --demangle--> nominal type descriptor for DemoKit.Foo.(Private in _00D91DAB7748ABA327DC94E69D678CAF)

We can then use swift-pd-guess to guess the file name using a given words array.

swift-pd-guess 00D91DAB7748ABA327DC94E69D678CAF Foo,Private,API,_,+, --prefix DemoKit
# Try brute force hash: 00D91DAB7748ABA327DC94E69D678CAF with dictionary ["Foo", "Private", "API", "_", "+"] max-4
# Found match: DemoKitFoo+Private.swift

The result is DemoKit/Foo+Private.swift since we are lucky to find a good words array.
