What are error handling patterns for RealityKit in Swift?

When working with RealityKit in Swift, error handling is crucial to create robust and fault-tolerant applications. Common ways to handle errors include using Swift's built-in error handling constructs like do-catch blocks, try statements, and the Result type. Developers can also employ custom error types for more granularity.

Here are some common patterns:

• Do-Catch Block: Wrap throwing functions in a do-catch block to handle any potential errors.
• Try Statements: Use try to call throwing methods within do-catch, be prepared to catch errors that may arise.
• Result Type: Use the Result type to represent success or failure, providing information about the error in a clean manner.

Here's an example of handling errors in RealityKit:

            do {
                let entity = try Entity.loadModel(named: "model.usdz")
                // Add entity to the scene
            } catch {
                print("Error loading model: \(error)")
            }
