* Remove link previews: link URLs inline\n\n- Delete LinkPreviewView and all references\n- Strip preview usage from ContentView\n- Make detected URLs tappable via .link attribute\n- Add MessageTextHelpers for tokens/length checks\n- Wire helpers into iOS/macOS targets * Peer list UX: match message colors, use map pin icon, stable ordering\n\n- Color list names and icons with same peer color as messages\n- Default icon mappin; teleported uses face.dashed (iOS)\n- Geohash: move teleported peers to bottom\n- Maintain stable order: append new peers, remove missing\n- Mesh list: replace state icons with colored mappin/person * Fix peer list build errors: remove ambiguous Set type, avoid guard in ViewBuilder, remove duplicate bindings, and simplify person lookup * Peer list: remove onChange expressions to avoid type-check issues; rely on ObservedObject updates * Peer lists: simplify view structure to satisfy SwiftUI type checker (replace Group with VStack, flatten body) * Peer lists: move ordering mutations to onAppear/onChange, keep body pure; fix result builder errors * Fix: remove trailing modifiers outside if/else to avoid ViewBuilder type issues * Color parity: fix seed cache to include color scheme; normalize Nostr seeds; switch to mappin.circle icon * Peer colors: ensure exact match with message colors\n\n- Mesh list uses same seed logic as messages (getNoiseKeyForShortID fallback)\n- Color cache keyed by theme; normalize nostr seeds\n- Icons: use mappin.and.ellipse (default) and face.dashed for teleported\n- Teleport tag: accept "teleported" in addition to "teleport" and presence events * Fix geohash color mismatch: populate nostrKeyMapping before building messages in resubscribe; also honor t,teleport tag for teleported state * Message actions: username tap opens sheet via clickable AttributedString; message tap inserts @mention; rename to 'direct message' * Cashu UX: suppress 'Show more' when message contains a Cashu token (chips handle rendering) * Cashu detection: broaden regex (allow '.') + shorter min length; avoid long-text fallback when Cashu present so chips render and no full blob * Geohash levels: rename region->province, country->region; update labels, precision, UI, manager mapping, tests; add Codable backward-compat for renamed cases * Fix braces in LocationChannel.swift: close enum before extension to satisfy file-scope declarations * Geohash links: make #geohash tappable and open that channel (bitchat://geohash/<gh>); handle in ContentView.onOpenURL with validation and selection * Underline tappable #geohash mentions for clarity * Geochat: sanitize timeline on channel switch to remove any blank-content entries (prevents blank rows) * Xcode project: sync sources after UI changes (remove LinkPreview, add helpers, update build refs) --------- Co-authored-by: jack <jackjackbits@users.noreply.github.com>
bitchat
A decentralized peer-to-peer messaging app that works over Bluetooth mesh networks. No internet required, no servers, no phone numbers. It's the side-groupchat.
Warning
Private messages have not received external security review and may contain vulnerabilities. Do not use for sensitive use cases, and do not rely on its security until it has been reviewed. Now uses the Noise Protocol for identity and encryption. Public local chat (the main feature) has no security concerns.
License
This project is released into the public domain. See the LICENSE file for details.
Features
- Decentralized Mesh Network: Automatic peer discovery and multi-hop message relay over Bluetooth LE
- Privacy First: No accounts, no phone numbers, no persistent identifiers
- Private Message End-to-End Encryption: Noise Protocol
- IRC-Style Commands: Familiar
/slap,/msg,/whostyle interface - Universal App: Native support for iOS and macOS
- Emergency Wipe: Triple-tap to instantly clear all data
- Performance Optimizations: LZ4 message compression, adaptive battery modes, and optimized networking
Technical Architecture
Binary Protocol
bitchat uses an efficient binary protocol optimized for Bluetooth LE:
- Compact packet format with 1-byte type field
- TTL-based message routing (max 7 hops)
- Automatic fragmentation for large messages
- Message deduplication via unique IDs
Mesh Networking
- Each device acts as both client and peripheral
- Automatic peer discovery and connection management
- Adaptive duty cycling for battery optimization
For detailed protocol documentation, see the Technical Whitepaper.
Setup
Option 1: Using XcodeGen (Recommended)
-
Install XcodeGen if you haven't already:
brew install xcodegen -
Generate the Xcode project:
cd bitchat xcodegen generate -
Open the generated project:
open bitchat.xcodeproj
Option 2: Using Swift Package Manager
-
Open the project in Xcode:
cd bitchat open Package.swift -
Select your target device and run
Option 3: Manual Xcode Project
- Open Xcode and create a new iOS/macOS App
- Copy all Swift files from the
bitchatdirectory into your project - Update Info.plist with Bluetooth permissions
- Set deployment target to iOS 16.0 / macOS 13.0
Option 4: just
Want to try this on macos: just run will set it up and run from source.
Run just clean afterwards to restore things to original state for mobile app building and development.
