# AnyTransientAppEntity

A type-erased representation of a transient app entity that provides dynamic property access.

## Declaration

```swift
@dynamicMemberLookup struct AnyTransientAppEntity
```

## Overview

Overview Use AnyTransientAppEntity to work with transient entities when you don’t know the specific entity type at compile time. // Getting transient entity definitions. let definitions = IntentDefinitions(bundleIdentifier: "com.apple.example") let sessionEntity = definitions.transientEntities["UserSessionEntity"]

// Creating a transient entity with properties. var entity = sessionEntity.withProperties(     name: "John Doe",     age: 30 )

// Accessing properties with type safety. let userName: String? = try entity.name let userAge: Int? = try entity.age

// Accessing nested properties (requires try). if try entity.profile.name == "John Doe" {     print("User found") }
