# TeleTuiIOS
Native SwiftUI shell for the iOS client.
Current scope:
- 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:
```bash
cd apps/ios/TeleTuiIOS
swift run TeleTuiIOSSmokeTests
```
Simulator/device build is currently blocked on this machine because `xcodebuild -version` fails with:
```text
xcode-select: error: tool 'xcodebuild' requires Xcode, but active developer directory '/Library/Developer/CommandLineTools' is a command line tools instance
```
