[swift-users] Implementing a few statistics functions in Swift

Hey everyone, I would like to implement a few statistics functions in Swift (e.g. variance, standardDeviation, etc) that are computed over a collection. I am aware of this library: https://github.com/evgenyneu/SigmaSwiftStatistics My problem

[swift-users] Monorepo workflow using SPM

The Swift Package Manager is a great addition to the Swift programmer's toolbelt and in general I like the integration with Git. However, since SPM promotes a separate Git repo per package and actually leverages Git tags to resolve dependency versions, I am wondering if it's possible to use the

[swift-users] Binary package dependencies

Hi, It would be great to be able to depend on 'binary' (i.e. precompiled) modules/packages using SPM. This would allow distribution of proprietary modules without the underlying source code, which is an important use-case. AFAIK, this is not possible at the moment, but I would love to be proven

[swift-users] inout generic struct parameter error

While getting my feet wet with Swift, I am still surprised with type-system ‘quirks’ here and there. I tried to implement a simple array of weak references: public struct WeakArrayIterator: IteratorProtocol { var array: [Weak] var index = 0 init(_ array: [Weak]) { self.a

[swift-users] How to use an SPM library in an (Xcode based) iOS project?

I have created a nice little library with SPM ($ swift package init --type=library). The library includes some utility classes and associated tests. It works as expected. Now, I would like to use this library within an iOS application. AFAIK, SPM doesn't support iOS at the moment. I am wondering

[swift-users] XML parsing on Linux, with Swift 3.1

Hi, I would like to parse an RSS feed using Swift 3.1 on Linux. I tried to use Foundations’s XML but I only managed to get segmentation faults. Is this supposed to work on Linux? I have only seen examples on iOS. Apart from that a quick search didn’t reveal any useful XML parsing library compat

Re: [swift-users] XML parsing on Linux, with Swift 3.1

FWIW, I also prefer snake_case, but camelCase is unfortunately the standard convention in Swift so I use that. Also, I avoid using libraries that don’t follow standard conventions. -g. ___ swift-users mailing list swift-users@swift.org https://lists.s

[swift-users] Is URLSession actually working on Linux

I implemented a simple RSS feed aggregator. I used code like... let data = try! Data(contentsOf: feedURL) or let session = URLSession(configuration: URLSessionConfiguration.default) let task = session.dataTask(with: url, completionHandler: completionHandler) task.resume() ...to fetch the data.
