In Xcode9, there is a new feature to use scalable PDFs as your image assets and preserve the vector data.
Adding that image via code seems to produce the desired effect of a scaled image, but when adding a UIImageView in storyboards with constraints and referencing that image, it does not scale as expected.

Steps to Reproduce:
1. Create an Xcode project.
2. Import a scalable, PDF vector into the Image Assets and check the "Preserve Vector Data" checkbox.
3. Add an UIImageView with a height + width constraint and select the above UIImage.
4. Run the app.

Expected Results:
The added image should scale it's vector data and be clear.

Observed Results:
The added image is blurry and not scaled properly.
