Custom font none installed - Xcode 11 beta

Question

After installing the new beta xCode. The custom font set in an existing project does not work. When opening the storyboard file, it says as shown in image below

After clocking ok, I'm not able to choose custom font from the attribute inspector.

It was working fine with xcode 10.2. This issue occurs only on Xcode 11 beta

I've also had this issue.

I had to change the text style to attributed, pick the font, then change back to plain.

Answer 2

切换系统语言后，我遇到了同样的问题，此问题已通过重新启动系统然后重新启动Xcode来解决。

2. Drag-Drop your font into the Font Book.
3. Restart Xcode and it'll work fine.
