In my previous series "Learning Rust". I decided to attempt to learn some fairly basic rust concepts and constructs by working on a fairly simple project. This seemed to go fairly well. So I am now going to attempt to work on the same project, but this time, using Swift.
This will be a package based project. There will be no UI being developed.
Setting up the Development Environment
Creating the Project Directory Structure
For this I did some searching and decided to follow this guide using the Xcode approach (Option 2).
I created a directory called SPFLibrary and created the package with the name DeconSpf
What Xcode Creates
.
└── DeconSpf
├── Package.swift
├── README.md
├── Sources
│ └── DeconSpf
│ └── DeconSpf.swift
└── Tests
├── DeconSpfTests
│ ├── DeconSpfTests.swift
│ └── XCTestManifests.swift
└── LinuxMain.swift
-
Sources/DeconfSpf/is where the code for this project will reside. -
Testsis where our tests will reside obviously. - A point to note here is, based on my experience so far, we can not directly call our code within the files located under
Sources/DeconSpf. Xcode will complain. You actually need to write the code as tests underTest. - Xcode defaults to using main for the branch name.
This all creates a working package with a test that also passes.
DeconSpf.swift
struct DeconSpf {
var text = "Hello, World!"
}
DeconSPfTests.swift
import XCTest
@testable import DeconSpf
final class DeconSpfTests: XCTestCase {
func testExample() {
// This is an example of a functional test case.
// Use XCTAssert and related functions to verify your tests produce the correct
// results.
XCTAssertEqual(DeconSpf().text, "Hello, World!")
}
static var allTests = [
("testExample", testExample),
]
}
Running an initial Test
swift test
This produces the following output in the terminal, you can of course trigger the test in Xcode and get nice green icons.

Let's stop there for today. I will take up the next steps soon.
