Swift ComposeResultModel: Creating and Initializing Model Instances

You can create and initialize an instance of the `ComposeResultModel` class with the desired values. Here's an example of how you can do it: \n\nswift\nclass ComposeResultModel: NSObject {\n var height: CGFloat!\n var str: String = \"\"\n \n init(height: CGFloat, str: String) {\n self.height = height\n self.str = str\n }\n}\n\n// Usage\nlet height: CGFloat = 10.0\nlet str = \"Hello, World!\"\n\nlet resultModel = ComposeResultModel(height: height, str: str)\n\n\nIn this example, `resultModel` is an instance of `ComposeResultModel` with the `height` property set to `10.0` and the `str` property set to "Hello, World!".
