Noticed that Swift libraries that are to be run on Linux have one slight variation in the testing that is missing from SwiftPlate.

Swift Package Manager (swift package init --type library) does additionally the following:

In Tests/{PROJECT}Tests/{PROJECT}Tests.swift it adds:

    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({PROJECT}().text, "Hello, World!")
    }
    static var allTests : [(String, ({PROJECT}Tests) -> () throws -> Void)] {
        return [
            ("testExample", testExample),
        ]
    }

the example assert is related to boilerplate code in the Sources/ implementation, but the allTests is more interesting, as that is the convention for the slightly different testing flow for Swift encountered under Linux.

For Linux it adds another, related file Tests/LinuxMain.swift. Its contents:

import XCTest
@testable import {PROJECT}Tests

XCTMain([
     testCase({PROJECT}Tests.allTests),
])

Could the "cross-platformness" of SwiftPlate be updated to include libraries on Linux?

Not sure if I'm being stupid here or not, but what's the best way of managing subdependencies with this? For Cocoapods I could specify them in the podspec via s.dependency ... but can't really install them without a Podfile (something that would require an .xcworkspace as well).

Also those using the framework project built like this will probably have to use my dependency manager of choice as well, which is far from ideal. Is there a way to work around this? Or is it just not practical working with subdependencies when making a framework for use with all three currently used dependency managers?

Hi John, First of all, thanks for this tool, it has been very helpful for me. Do you think that an option to enable the "Gather coverage data" for all the testing targets would be useful? Does it suit in this project? If so, I would like to work on that and prepare a PR.

• Did NOT add a question about Linux support. Instead, added to Templates/ code that will still work unchanged under macOS, *OS. This is related to other details that I will describe.

• do not see a conventional way to conditionally include snippets into a Template/ output file, so instead I added a conditional extension for Linux only. Snippets ability would be useful in many ways: include example unit testing code and an example object (struct, e.g.) in the Sources/ if, and only if, an optional Boolean such as "Linux Unit testing support" was added to user prompt.

• tested under macOS. running testStructure.py passed.

• compilation under Linux will fail, due to testExample not being defined (see above about example unit testing code)

It looks like the generated files have the MIT License put in by default at the top of all files. Though it doesn't really make a difference to my org (we're open sourcing most of our stuff), people might have a problem with it.

Instead of throwing an error if a directory doesn't exist, the script now generates directories dynamically.

Just a rough/dirty implementation for now.

Hi John,

I'm using the brew version of SwiftPlate and found a few issues that already have been fixed on master. Looks like a lot of things have been fixed since the last release. Can you consider making a new brew version?

• since the file has non-ASCII characters, it can fail with a compile error if the doc type is not specified. This edit corrects for that.

Platform: macOS 10.12, Python 2.7.12

Error example

$ python ../SwiftPlate/testStructure.py test

File "testStructure.py", line 30
SyntaxError: Non-ASCII character '\xe2' in file testStructure.py on line 30, but no encoding declared; see http://python.org/dev/peps/pep-0263/ for details

Hi! SwiftPlate is awesome, thanks for creating it. I was wondering if it makes sense to include a default .gitignore file for Xcode/Swift projects, I've seen other tools like this doing it.

This PR replaces the MIT headers in {PROJECT}.swift and {PROJECT}Tests.swift with headers Xcode would generate.

But I am not sure how to handle different licenses.

Not sure if this is a requirement for this project-- or is supported-- but wanted to put an issue out there. It might never be supported.

I do not need this for myself as I can build/run SwiftPlate on macOS, and once I have the boilerplate build, I can use git clones to share in Linux environment.

building under linux

I tried to build SwiftPlate from recent clone on Linux (Ubuntu 16.04), and get build errors. Most of them look like they are Swift Core library/Foundation related, which is known to be lagging in completeness compared to macOS/*OS.

$ swift ../SwiftPlate/main.swift test
../SwiftPlate/main.swift:56:16: error: value of type 'ObjCBool' (aka 'Bool') has no member 'boolValue'
        return objCBool.boolValue
               ^~~~~~~~ ~~~~~~~~~
../SwiftPlate/main.swift:176:19: error: use of unresolved identifier 'Process'
    let process = Process()
                  ^~~~~~~
Foundation.NSProgress:1:12: note: did you mean 'NSProgress'?
open class NSProgress : Foundation.NSObject {
           ^
Foundation.ProcessInfo:1:12: note: did you mean 'ProcessInfo'?
open class ProcessInfo : Foundation.NSObject {
           ^

Process changed to CommandLine?

I didn't really dig much into these errors. Googling the Process() one yielded something that would appear to related, but after further investigation, I do not think it is: Rename Process to CommandLine [SE-0086] https://github.com/apple/swift/commit/f65c1390cb23395fde5a798fb6731b32a31ec452

The change referred to has been in place for a while on Swift 3 branch.

I was able to confirm that Process is available in Foundation on macOS, but is not present in Foundation on Linux (at this time).

If I will generate project using swiftplate there isn't path attribute in target in Package.swift. Because of that I am unable to install framework as dependency through package manager.

After adding path: "Sources" installation is possible.

Maybe I'm missing something ? 🤔 It work well without the option -r

I use cookiecutter and my custom template for project generation. I guess you have the same problem - it's very hand to update or create a new template. How you do it? It would be great if you add a command for template generation based on existing project. I want to write a script for it, but if you have a plan for it, I'll wait 😃
