http://releases.ubuntu.com/14.04/

(2) Virtual Box 5.0 from https://www.virtualbox.org/wiki/Downloads
Virtual Harddisk of 20G or above is recommended.

(3) Install clang in ubuntu 14
sudo apt-get update
sudo apt-get --assume-yes install clang-3.4 libicu-dev git vim

(4) download swift in ubuntu 14
curl -O https://swift.org/builds/ubuntu1404/swift-2.2-SNAPSHOT-2015-12-31-a/swift-2.2-SNAPSHOT-2015-12-31-a-ubuntu14.04.tar.gz
tar xzvf swift-2.2-SNAPSHOT-2015-12-31-a-ubuntu14.04.tar.gz
export PATH=$HOME/swift-2.2-SNAPSHOT-2015-12-31-a-ubuntu14.04/usr/bin:$PATH

(5) test compile
swift --version
echo 'print("Hello World")' > helloworld.swift
swiftc helloworld.swift
./helloworld

(6) remember to Insert Guest additions CD-image and reboot the virtual host.

(7) Test build
cd ${HOME}
git clone https://github.com/apple/example-package-dealer.git
cd example-package-dealer
swift build
.build/debug/Dealer

(8) Test build by adding swift package

shell script    Select all

cd ${HOME} mkdir -p teststring cd teststring cat > Package.swift <<EOF import PackageDescription let package = Package( name: "teststring", dependencies: [ .Package(url: "https://github.com/erica/SwiftString.git", majorVersion: 1), ] ) EOF cat > main.swift <<EOF import SwiftString let line = "apple,peach,kiwi" let parts = line.componentsSeparatedByString(",") print(parts) EOF swift build (cd Packages/SwiftString-1.0.5; git pull) swift build .build/debug/teststring

(9) Test build by adding C module
sudo apt-get install -y libcurl4-gnutls-dev libjson-c-dev
cd ${HOME}
git clone https://github.com/iachievedit/moreswift
cd moreswift/translator_swiftpm
swift build
.build/debug/translator "Hello" from "en" to "zh-cn"
