Unfortunately, there's no quick fix for Segmentation fault: 11. In some limited cases, Clean Build Folder or removing derived data might work, but not for all cases.

The first thing you should do is finding out which Swift file is (or which Swift files are) causing the issue. How many Swift files do you have in your project?

Did you get messages in Issue Navigator to migrate to Swift5 or similar message ?
