SF UI Display doesn't work on Xcode?

Question

I am using the SF UI Display for iOS on Xcode and I chose the Ultralight option, and this is what shows up on the storyboard (the correct version)

This is what shows on the simulator when I run it, it looks much bolder and doesn't seem right...

Since San Francisco is the System Font, no need to choose custom and use San Francisco, just use system.

I'm using system on the latest Xcode and it's not showing the San Francisco font. If I set it manually in code, it does show the .SFUIDisplay Font, but on the simulator it looks the same as Helvetica. – Rodrigo Ruiz Jul 13 '17 at 19:47

If it's a button, try this

[button.titleLabel setFont:[UIFont systemFontOfSize:size weight: UIFontWeightUltraLight]];

If it's a label, try this:

[label setFont:[UIFont systemFontOfSize:size weight: UIFontWeightUltraLight]];

In each of those cases, replace "size" with your desired font size.
