Bloom

🔒 Secured as a Bank • ☎️ Simple as SMS • 🏎 Fast as Formula 1

A next-generation iOS messaging experience built purely in Swift & SwiftUI. Features heavy emphasis on UX, FaceID security, custom Metal shaders, and Liquid glass.

---

✨ What makes it cool?

• Custom Navigation Engine: Goodbye default NavigationStack. Bloom uses a custom, highly responsive, gesture-driven AppRouter with spring physics and depth-scaled transitions.
• Metal Shaders at the Core: Hardware-accelerated UI features including the buttery smooth Ambient Underglow and a hypnotic Gooey Effect (.metal shaders integrated directly with SwiftUI).
• Liquid glass Built-in: Built-in native Liquid glass support with planning for iOS 18
• Zero-Compromise Security: Native, root-level biometric barrier (FaceID) required to unlock the experience.
• Performant by Design: Fully built on the new SwiftUI @Observable macro framework ensuring minimal view reloads and top-tier frame rates.

🛠 Tech Stack & Under the Hood

• UI Framework: SwiftUI & Custom CoreGraphics
• Language: Swift 6.0+ (Utilizing modern concurrency: async/await, Task, @MainActor)
• State Management: Native @Observable
• Authentication: LocalAuthentication (Biometrics / Face ID)
• External SPM Dependencies:
  • LiquidGlassKit — Liquid glass components and iOS 18 support.
  • BlurUIKit / BlurSwiftUI — Advanced varying blurs and dimming overshoot.
  • lottie-spm — High quality vector animations (e.g. animated Face ID icon).

Highlighted Architecture Features

• Custom Bottom Sheets: Highly interactable, drag-aware, pan-gesture-based modal controllers without relying on iOS native partial sheets.
• Intelligent Keyboard Awareness: Uses custom UIViewController wrappers (KeyboardPinnedView) to magically pin inputs atop keyboards perfectly matched with UIKit physics.
• Theme Engine: Global configuration handling typography (Open Runde font family), line spacing, and dynamic hex colors effortlessly (Theme.swift).

🚀 Getting Started

Requirements

• Xcode 26.0+
• iOS 26.0+ target device/simulator
• An iOS device with FaceID is heavily recommended to test the native auth flow properly.

Installation

1. Clone the repository:

   git clone https://github.com/slipe-fun/Bloom-iOS.git
   cd Bloom-iOS

2. Open the project in Xcode:

   open Bloom.xcodeproj

3. Let SPM resolve dependencies automatically.
4. Set your Signing / Team in the target settings.
5. Hit Cmd + R (▶) to build and run!

🔐 Security Note

The application requests FaceID immediately upon booting (WelcomeScreen). The fake BiometricAuthManager demonstrates unlocking the internal router. Since iOS Simulator can test FaceID (Features > FaceID > Enrolled), verify you've enrolled it before tapping "Continue with FaceID".
