struct MyParameters {
    var position: CGPoint
    var size: Float
  }

 var parameters = MyParameters(position: .zero, size: 0)
 let pointer = UnsafeMutableRawPointer(&parameters)

 Initialization of 'UnsafeMutableRawPointer' results in a dangling pointer

func foo() {
    var parameters = MyParameters(position: .zero, size: 0)
    
    withUnsafeMutableBytes(of: &parameters) { pointer in
         // here the lifetime is known
    }
}
