* android, desktop, ios: show chat name in delete / leave / clear confirmation dialogs The dialogs confirming delete contact, delete/leave group/channel and clear chat now show the chat's name on its own line above the existing warning, so the user can see which chat the destructive action will affect. Pure code change: no new translation strings, no signature changes, no new helpers. The name is read via existing displayName accessors on GroupInfo / Contact / ChatInfo. clearNoteFolderDialog is intentionally unchanged - the notes folder is a single-instance object and its existing warning already identifies it. * android, desktop, ios: also show chat name when deleting pending connection deleteContactConnectionAlert was missed in the original inventory. Same pattern as the other dispatchers - prepend the connection's displayName on its own line above the existing warning - so a user who set a custom name on a pending connection can see which one they are about to delete. * android: use <br> instead of \n for newline in delete confirmation dialog body On Android, the alert body goes through HtmlCompat.fromHtml which treats the input as HTML and collapses literal \n to a single space - so "Tech Talk\n\nGroup will be deleted..." rendered as "Tech Talk Group will be deleted...". Switch to <br><br>, which both HtmlCompat (Android) and the Desktop parser at Utils.desktop.kt:75 correctly render as a newline. * android, desktop: skip HTML parsing for delete confirmation dialog text Add parseHtml: Boolean = true parameter to showAlertDialog and showAlertDialogButtonsColumn; when false, the body text is wrapped as AnnotatedString and routed through the existing AnnotatedString AlertContent overload, bypassing escapedHtmlToAnnotatedString entirely. The 8 dispatchers that embed the user-controlled chat displayName now opt out (parseHtml = false). This means: - displayName is rendered as literal text - no HTML interpretation, so a contact whose alias is "<b>X</b>" or "<font color=..." no longer renders bold or coloured in the confirmation dialog - the platforms align: both iOS and Kotlin now use plain "\n\n" for the separator (no more <br><br> Kotlin-only workaround) - removes coupling to escapedHtmlToAnnotatedString in this path * android, desktop: shorten parseHtml comment in AlertManager * remove extra text --------- Co-authored-by: Evgeny Poberezkin <evgeny@poberezkin.com>
SimpleX Chat iOS app
This file provides guidance when working with code in this repository.
iOS App Overview
The iOS app is a SwiftUI application that interfaces with the Haskell core library via FFI. It shares the SimpleXChat framework with two extensions: Notification Service Extension (NSE) for push notifications and Share Extension (SE) for sharing content from other apps.
Build & Development
Open SimpleX.xcodeproj in Xcode. The project has five targets:
- SimpleX (iOS) - Main app (Bundle ID:
chat.simplex.app) - SimpleXChat - Framework containing FFI bridge and shared types
- SimpleX NSE - Notification Service Extension
- SimpleX SE - Share Extension
- Tests iOS - UI tests
Build and run via Xcode (Product > Build/Run). Tests run via Product > Test or:
xcodebuild test -scheme "SimpleX (iOS)" -destination 'platform=iOS Simulator,name=iPhone 15'
Deployment target: iOS 15.0+, Swift 5.0.
Architecture
Haskell Core Integration
The app calls the Haskell core library through C FFI defined in SimpleXChat/SimpleX.h:
chat_migrate_init_key()- Initialize/migrate databasechat_send_cmd_retry()- Send command to chat controllerchat_recv_msg_wait()- Receive messages from controller
Swift wrappers in SimpleXChat/API.swift:
chatMigrateInit()- Initialize chat controllersendSimpleXCmd<R>()- Send typed commands and parse responsesrecvSimpleXMsg<R>()- Receive typed messages
Haskell runtime initialization (SimpleXChat/hs_init.c) uses different memory configurations:
- Main app: 64MB heap
- NSE: 512KB heap (minimal footprint for background processing)
- SE: 1MB heap
Pre-compiled Haskell libraries are in Libraries/{ios,mac,sim}/.
State Management
- ChatModel (
Shared/Model/ChatModel.swift) - Main singletonObservableObjectfor app-wide state (chat list, active chat, users) - ItemsModel - Manages chat items within a selected chat (similar to Kotlin's ChatsContext)
- AppTheme - Theme management and customization
App Structure
Entry point: Shared/SimpleXApp.swift
Key directories in Shared/:
Model/- Data models and API layer (ChatModel.swift,SimpleXAPI.swift)Views/- SwiftUI views organized by feature:ChatList/- Chat list and user pickerChat/- Message display and compositionCall/- VoIP call UIUserSettings/- App settingsLocalAuth/- Passcode and biometric authenticationDatabase/- Database initialization and migration
Shared Data Between Targets
All three targets share data via App Group (group.chat.simplex.app):
SimpleXChat/AppGroup.swift- GroupDefaults wrapper for typed shared preferences- Keychain for sensitive data:
kcDatabasePassword,kcAppPassword,kcSelfDestructPassword
Key Types
Types are defined in SimpleXChat/:
ChatTypes.swift- User, Chat, Message, Group typesAPITypes.swift- API request/response types
Commands follow ChatCmdProtocol (has cmdString property), sent as JSON through FFI.
Localization
31 languages supported. Localization files in SimpleX Localizations/.
Workflow:
Product > Export Localizations- Export XLIFF filesProduct > Import Localizations- Import updated translations
SimpleX Assets
The app includes optional assets behind the SIMPLEX_ASSETS Swift compilation flag. Without setup, the app builds normally without them.
Setup
Create Local.xcconfig (gitignored) in the apps/ios/ directory:
SIMPLEX_ASSETS_DIR = /path/to/assets
SWIFT_ACTIVE_COMPILATION_CONDITIONS = $(inherited) SIMPLEX_ASSETS
The copy script (scripts/ios/copy-assets.sh) runs as a build phase on each build but exits immediately if SIMPLEX_ASSETS is not set.
Updating assets
When source images change, regenerate resized images (requires ImageMagick):
cd path/to/assets && ./resize.sh
Background Capabilities
Configured in Info.plist:
- Background modes: audio, fetch, remote-notification, voip
- URL scheme:
simplex://for deep linking - BGTaskScheduler:
chat.simplex.app.receive
