That's happens because you use the wrong System name for the font. Try to use
发生这种情况是因为您为字体使用了错误的系统名称。尝试使用
labelname.font = [UIFont fontWithName:@"SFUIText-Light" size:12];
How to find System font names see here Adding custom fonts to iOS app finding their real names

Adding an update: you should be using the system font APIs in UIFont. For example:
添加更新：您应该在 UIFont 中使用系统字体 API。例如：
UIFont.systemFont(ofSize: 12, weight: .light)
Apple specifically tells developers to no longer rely on a font name or file system representation for the system font.
Apple 特别告诉开发人员不要再依赖系统字体的字体名称或文件系统表示。
As an aside, I made up a library for using many of the special features of the SF font in your app. Feel free to check it out: https://github.com/djfitz/SFFontFeatures
顺便说一句，我创建了一个库，用于在您的应用程序中使用 SF 字体的许多特殊功能。请随意查看：https: //github.com/djfitz/SFFontFeatures

IMPORTANT, really.
重要的，真的。
Use this code, it is very, very useful. With it you can know the real name of the font.
使用此代码，它非常非常有用。有了它，您就可以知道字体的真实名称。
let fontFamilyNames = UIFont.familyNames
for familyName in fontFamilyNames {
print("------------------------------")
print("Font Family Name = [\(familyName)]")
let names = UIFont.fontNames(forFamilyName: familyName)
print("Font Names = [\(names)]")
}
I show you an example.
我给你举个例子。
The Font file (you must add it into your project, as any other file):
字体文件（您必须将其添加到您的项目中，就像任何其他文件一样）：
The Font file name in "Info.plist" (exactly the same name with the file extension):
“Info.plist”中的字体文件名（与文件扩展名完全相同）：
Finally, the output in the log Debug (created by the code)
最后在日志Debug中输出（由代码创建）
So, you can write this font name:
所以，你可以写这个字体名称：
headerLabel.font = UIFont(name:"SFProDisplay-Heavy", size:30)
Use this code. It has saved me time. It is very useful (I think)!
使用此代码。它节省了我的时间。这是非常有用的（我认为）！
