📚 Dependency docs

• UI: We use Texture to improve the performance, memory efficiency, and thread safety of the app.
• Storage: We use Realm as an alternative to SQLite.
• IMAP/SMTP provider: We use MailCore which provides an asynchronous API to work with the e-mail protocols.
• Icons: We use SF Symbols, a powerful resource for a vast collection of vector icons.

🛠️ Generating .ipa for penetration tester (Admin)

1. Get the UUID of their device and input it into the Apple Developer account ➜ Devices.
2. Choose the right build (e.g. FlowCrypt Enterprise) and choose Any iOS Device (arm64).
3. Xcode ➜ Product ➜ Archive.
4. Distribute app ➜ Add Hoc ➜ Next ➜ Next (automatically manage signing).
5. This creates a folder at the target where you export it, and the IPA will be there.
