xcode 8 "Command failed due to signal: Segmentation fault: 11"

Question

I updated my Xcode to Xcode 8 and accepted all the updates but I get an error telling me "Command failed due to signal: Segmentation fault: 11"

note that I am aware this question is very close to this one :

Xcode 7 compile error : "Command failed due to signal: Segmentation fault: 11"

also note I am using a parse server, I doubt it has anything to do with it but I thought I will mention it in case.

but it hasn't solved my issue, has anyone had this issue / solved it ?

thanks !

We encountered the same problem. This answer did solve our problem: Swift compiler segmentation fault when building

You have to unwrap all optionals before you can use them in a if statement.
