In My Model Wrapper file i have below code
public init(url: URL) {
print("url :\(url)")
self.model = try! TestModel(contentsOf: url)
}
This code works below iOS 13 very well.
Please guide.

Answer 1

The model will get compiled, when you bundle your app. For iOS 13 you have to search for .mlmodelc in your bundle, the .mlmodel file doesn't exist on your iPhone.

Answer 2

Use
URL(fileURLWithPath: modelDestination)
instead of
URL(string: modelDestination)
when creating the compiled url.
