Swift migration failed Segmentation fault: 11

Xcode 10 beta 2, when I launch the Swift Migration to Swift 4.2


it failed and it is saying


Segmentation fault: 11

Command Ditto failed with a nonzero exit code


However my project compiled successfully and if I go in the build settings and change the Swift Language to Swift 4.2,


I did the migration by manually by fixing all warnings and I don't have errors at the end,


it looks like a bug in the migration assistant


thanks
