Ambiguous Reference in Swift

Question

I reference two frameworks [PDFGenerator and PDFKit] that both contain an object named PDFPage. In the PDFGenerator framework, PDFPage is an Enum. In the PDFKit framework, PDFPage is an object. When I try to create an instance of the PDFPage Enum I get the error:

'PDFPage' is ambiguous for type lookup in this context'.

How do I specify which PDFPage I am trying to instantiate?

Simplified example below:

import PDFKit

import PDFGenerator

public class VC: UIViewController {
    var page:PDFPage? // <-- This throws the error mentioned above.
}

Please [search on the error](https://stackoverflow.com/search?q=%5Bswift%5D+is+ambiguous+for+type+lookup+in+this+context) — rmaddy, Sep 04 '18 at 05:34
you need to called its init method to solve issue using let page = PDFPage() — Hardik Thakkar, Sep 04 '18 at 06:06
As per this article [https://stackoverflow.com/questions/51952394/date-is-ambiguous-for-type-lookup-in-this-context], var page:PDFGenerator.PDFPage should be the answer. The reason this does not work in my example is because in the 'PDFGenerator' framework there is a public class also named 'PDFGenerator'. When I try to declare my variable as page:PDFGenerator.PDFPage it results in the error 'PDFPage' is not a member type of 'PDFGenerator'. Naming a class within a framework the same name as the framework itself may not be a good idea. — Deepak Sreedharan, Sep 05 '18 at 00:47

Try this code it will solve error.

import PDFKit
import PDFGenerator

public class ViewController: UIViewController {
    let page = PDFPage() // <-- This solve the error mentioned above.

    override public func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.
    }

    override public func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }
}

This compiles but does not solve my specific need to declare the variable as PDFKit.PDFPage. — Deepak Sreedharan, Sep 07 '18 at 03:45
