Release does not clear cached UIFont(s)

In the example below, I use resURL to indicate the URL to "SomeFontName" font.
In the last case, the UIFont is, unexpectedly, not nil, meaning the resources are not fully released.

var font: UIFont!

font = UIFont(name: "SomeFontName", size: 30) // font == nil, as espected

Elefont.eat(at: resURL)
font = UIFont(name: "SomeFontName", size: 30) // font != nil, as espected

Elefont.releaseEverything()
font = UIFont(name: "SomeFontName", size: 22) // font == nil, as espected
font = UIFont(name: "SomeFontName", size: 30) // font != nil, error!

After some investigation, it seems that the object returned in the last step is the same as in the second step, meaning the system returns a cached value.
