What’s in the Phantom iOS app?

Phantom is one of the most popular wallet in Solana blockchain ecosystem. Let’s look at what frameworks are inside Phantom iOS app v22.05.23:

➜  Phantom.app ls -1 Frameworks/
hermes.framework
libswiftAVFoundation.dylib
libswiftAccelerate.dylib
libswiftCore.dylib
libswiftCoreAudio.dylib
libswiftCoreFoundation.dylib

hermes

A JavaScript engine optimized for running React Native.

The rest libswift* exist for supporting iOS version earlier than 12.2 (currently supporting iOS 12.0 or later).

Phantom is developed with React Native:

➜  Phantom.app ls *.jsbundle
main.jsbundle

Since Phantom is not open source software, it is harder to know its dependencies. However, we could still take a glance here:
