Hello, There seems to be an issue when compiling Swifter on Xcode 10.2beta. The Errno.swift file produces a compilation error on [line](https://github.com/httpswift/swifter/blob/stable/Sources/Errno.swift#L13): `return String(cString: UnsafePointer(strerror(errno)))` The recommendation to fix this issue is to remove the call to the UnsafePointer. `return String(cString: strerror(errno))` You can also follow the discusson on [apple forums](https://forums.developer.apple.com/thread/113919) Cheers Plato
