Xcode 8 random command failed due to signal segmentation fault 11

Question

I have a strange problem with the new Xcode 8 (no beta version) and swift3.

Once every other 3-4 times that I compile my code I get a 'command failed due to signal segmentation fault 11' error. I just need to enter new empty line, or sometimes changing some spaces, or add a comment (everywhere in the code) and the error disappears and I can compile again. This is really strange because I'm not changing anything in the code! And sometimes I can compile and it works, then I don't change anything, I compile again and I get the error. This is really annoying!

I have noticed this is happening since I have installed several 'Firebase' pods (Firebase, Firebase/Auth etc...). But I need them.

Anyone has any suggestion?

PS: I have set the Enable Bitcode of my project to No as many solution suggested, but nothing. In the error message it is not indicated any swift page where the error can be, an example is:

1. While loading members for 'Class_name' at
2. While deserializing 'func_name' (FuncDecl #42)

'func_name' is this one:

public class func loginUser(fir_user: FIRUser) {
    let user = SFUser()
    user.email = fir_user.email 
    user.isLogged = true
    try! sfRealm.write() {
        sfRealm.add(user, update:true)
    }

    var userToAdd = [String:AnyObject]()
    userToAdd["email"] = fir_user.email! as NSString

    let ref=FIRDatabase.database().reference()
    let usersRef = ref.child(childName)
    usersRef.setValue([key:value])
}

But then, as I said, I can just enter an empty row in another file and it compiles!

Thanks
