You can use https://github.com/bofiaza/IPImage, but you must to do some corrections in function generateImage().

Change this code in source file:

public func generateImage() -> UIImage? {

    let view = setupView()

    UIGraphicsBeginImageContextWithOptions(view.bounds.size, false, 0.0)
    view.drawHierarchy(in: view.bounds, afterScreenUpdates: true)
    let image = UIGraphicsGetImageFromCurrentImageContext()
    UIGraphicsEndImageContext()
    print(image ?? "No image")
    return image
}

on this:

public func generateImage() -> UIImage? {

    let view = setupView()

    UIGraphicsBeginImageContextWithOptions(view.bounds.size, false, 0.0)
    defer { UIGraphicsEndImageContext() }
    guard let currentContext = UIGraphicsGetCurrentContext() else {
        return nil
    }
    view.layer.render(in: currentContext)
    let image = UIGraphicsGetImageFromCurrentImageContext()
    UIGraphicsEndImageContext()
    print(image ?? "No image")
    return image
}

It will be work correctly!
