SwiftUI + MVVM app shell backed by a deterministic fake bridge.
Auth, chat list, folder selector, chat detail, compose bar, profile sheet, and account switcher shell.
iOS-oriented storage boundaries: Keychain-shaped credential API and Application Support account paths.

Build and smoke-test the portable shell:

cd apps/ios/TeleTuiIOS
swift run TeleTuiIOSSmokeTests

Verify local iOS tooling:

DEVELOPER_DIR=/Applications/Xcode.app/Contents/Developer scripts/check-ios-prereqs.sh

Build the SwiftUI shell for iOS Simulator and package it as an installable .app:

DEVELOPER_DIR=/Applications/Xcode.app/Contents/Developer scripts/build-ios-simulator-app.sh

Launch the fake-backed app in the first available iPhone simulator:

DEVELOPER_DIR=/Applications/Xcode.app/Contents/Developer scripts/run-ios-simulator-app.sh

Run the simulator launch plus screenshot sanity check:

DEVELOPER_DIR=/Applications/Xcode.app/Contents/Developer scripts/smoke-ios-simulator-ui.sh
