Hi @taylor211. Did you ever find an answer or workaround to this? I have the same issue, and am not looking forward to coming up with a workaround. Not sure what attributes you're using, but it seems to be ignoring, or perhaps a different defaulting, of line heights. I will add however that it is not specifically Xcode 11. If you set the target platform to a minimum of macOS 10.13 in Xcode 11, you will get the original behaviour, even on 10.14 and 10.15. Change it to a minimum of 10.14, and you once again get the new changed behaviour. To me this sounds like the 10.14+ libraries are the issue.

I fixed this problem by adding an explicit lineHeightMultiple (in my case varying from 1.0-1.2), in the paragraph style (that I had already added) spanning the entire attributed string, instead of letting lineHeightMultiple default.

Same issue here, Xcode 16 build on previously working Xcode 15. It looks like Xcode 16’s settings conversion is clearing the setting, or has changed the default setting for Debug Information Format. I’ve found the following removes the error and allows distribution. Go to your target's Build Settings and enter "debug information format" in the search field. For Debug, Release and Test, make sure the setting is "DWARF with dSYM File". Now Clean Build Folder and then Archive.
