Don’t use “swift” unless you want to run the REPL. Here’s how you should build a package that runs tests: 

local at ubuntu:~/Documents$ mkdir XTest
local at ubuntu:~/Documents$ cd XTest/
local at ubuntu:~/Documents/XTest$ touch Package.swift
local at ubuntu:~/Documents/XTest$ emacs -nw main.swift
local at ubuntu:~/Documents/XTest$ swift build
Compiling Swift Module 'XTest' (1 sources)
Linking Executable:  .build/debug/XTest
local at ubuntu:~/Documents/XTest$ .build/debug/XTest
Total executed 0 tests, with 0 failures (0 unexpected) in -nan (0.0) seconds
