Bug with .lineSpacing attribute

[baevra]

.lineSpacing + .tracking or .adapt

.lineSpacing only

.lineSpacing + .tracking or .adapt

This bug appears only with single line strings, this is not a BonMot bug, its probably NSAttributedString bug
@ZevEisenberg Any ideas?

@baevra would you mind posting a sample project, preferably without BonMot so that we can confirm that it’s an NSAttributedString bug? Then, I or someone else might be able to think of a workaround. But also, it will give you a good sample project to send to Apple as a bug report.

I found that .writeDirection + .lineSpacing also creates empty space
To fix this issue I created a wrapper (UIView) around UILabel that is calculates size in sizeThatFits and forces height to be equal to font.lineHeight if labels sizeThatFits returns height < font.lineHeight * 1.5 + .lineSpacing its weird but it works :D

In iOS 13 its works as expected
