error: cannot convert value of type 'ObjCBool' to expected argument type 'Bool' on Swift 4.1.2 and Kitura on Ubuntu 16.04

I have a plain vanilla Ubuntu 16.04 and installed OpenSSH, Curl and Swift 4.1.2 on it. The base example (swift package init --type executable) works but when I want to use Kitura framework I got a compile error if I 'swift build' it.

The error:

/.build/checkouts/Kitura.git--4845395383860597130/Sources/Kitura/staticFileServer/FileServer.swift:138:21: error: cannot convert value of type 'ObjCBool' to expected argument type 'Bool'
            if !isDirectoryBool {
                ^~~~~~~~~~~~~~~

error: terminated(1): /home/thewall/swift-4.1.2-RELEASE-ubuntu16.04/usr/bin/swift-build-tool -f /home/thewall/zSwift/.build/debug.yaml main output:

My package.swift file looks like:

import PackageDescription

let package = Package( name: "zSwift", dependencies: [ .package(url: "https://github.com/IBM-Swift/Kitura.git", >.upToNextMinor(from: "2.1.0")), ], targets: [ .target( name: "zSwift", dependencies: ["Kitura"]), ] )

uname -a gives:

Linux thewall 4.10.0-28-generic #32~16.04.2-Ubuntu SMP Thu Jul 20 10:19:48 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux

Any ideas?

Solution

  • Kitura is handling it correctly, see https://github.com/IBM-Swift/Kitura/blob/master/Sources/Kitura/staticFileServer/FileServer.swift#L95

    However, you are using an outdated Kitura version that has not been updated for your Swift version. Please, update Kitura to the latest version which is currently 2.4.1.
