Incompatible with latest Frida

[pandasauce]

Steps:

1. Compile a script with just const Swift = require('./swift-frida/index.js');
2. Spawn an iOS app with this script using frida -U -l tmp.js -f app.name
3. Script crashes with Failed to load script: gDBus.Error:re.frida.Error.InvalidArgument: Script(line 5): SyntaxError: parse error
4. This does not occur when running scripts built with frida-compile that don't rely on this library.

This is line 5: let convention;

Using a iOS 11.1 device, Frida 12.2.14.

Weird! Happens to me, too. But it seems to work when requiring the directory without the index.js. Seems like a bug in frida-compile/babelify to me, but I can't say I know a lot about the node module system.

If I omit index.js, compiling doesn't work at all:

Error: Cannot find module 'babelify' from '~/ff/swift-frida'

Managed to resolve this. Usage instructions are missing a critical step:

cd swift-frida
npm install

This installs npm dependencies for swift-frida at the versions from package.json
