Swift calling into GNUStep Progress
github: https://github.com/austintatiousness/GNUStepSwiftBridge
このスレッドに中に、swift から GNUstep gui を呼び出した画像があります。
この gui 呼出しにトライしてみました。
実行結果
（ウィンドウサイズ等は変えてあります）
以下がその方法です。
GNUstep
GNUStepSwiftBridge project には、
This project is a Swift interface for GNUStep's version of AppKit.
This project assumes that you are running OnFlapp's GNUStep Desktop project.
とあります。
そこで、 OnFlapp's GNUStep Desktop をインストールしておきます。
OnFlapp's GNUStep Desktop https://github.com/onflapp/gs-desktop
インストールは、記された手順通りにすれば、問題なく行えます。
Lubuntuの repo からのインストールと異なり、システムのルートディレクトリに
/Applications , /Developer , /Library , /System が作成され、そこにインストール
される。
Swift
Linux のシステムは、これまで使用している Lubuntu をそのまま利用します。
Swiftは、バージョンを5.8.1 にして、前回同様インストールします。
GNUStepSwiftBridge
上記の github からダウンロードし、任意の場所に保存します。
準備が整ったら、GNUStepSwiftBridge のルートディレクトリから、
swift run NSWindowTest
と実行します。import AppKit のエラーが出ます。
これは、AppKit ライブラリを呼び出していますが、このプロジェクト内に
AppKit ライブラリが定義されていません。ライブラリが期待される場所（Sources/AppKit）に AppKit.swift がありますが、内容がライブラリと異なっています。
その関連を調べていたら、update メッセージの中にそれらしきものがありました。
それをもとに書き直した AppKit.swift です。

この AppKit.swift をライブラリとして利用できるように、Package.swift を編集
します。

import PackageDescription
let package = Package(

NSWindowTest、HolloWorld の main.swift を以下のように編集します。
どちらも数行程、編集や追加を行っています。
NSWindowTest
main.swift
// The Swift Programming Language
// https://docs.swift.org/swift-book
import Foundation
import FoundationGNUStep
import libobjc2
import AppKitGNUStep
import ObjCSwiftInterop

@main
struct App {
static var window = NSWindow()
static var window2 = NSWindow()
//static var label = NSLabel()
static var label = NSTextField()
static var button = NSButton()
static func main() {
print("Hello World Times Two")
//var poolClass = objc_getClass("NSAutoreleasePool")
//var poolClassAllocated = forSwift_objcSendMessage(&objc_getClass("NSAutoreleasePool")!.pointee, sel_registerName("alloc"))
//_ = forSwift_objcSendMessage(&poolClassAllocated!.pointee, sel_registerName("init"))
let napClass = objc_getClass("NSApplication")
var sharedApp = forSwift_objcSendMessage(&napClass!.pointee, sel_registerName("sharedApplication"))
App.window.orderFront(sender: nil)
App.window.setBackgroundColor(NSColor(red: 1.0, green: 1.0, blue: 0.0, alpha: 0.5))
App.label.frame = .init(x: 20, y: 20, width: 200, height: 32)
App.label.setBackgroundColor(NSColor(red: 1.0, green: 1.0, blue: 0.0, alpha: 1.0))
App.window.addSubview(App.label)
let image = NSImage.image(named: "Dummy")
App.button.frame = .init(x: 50, y: 100, width: 100, height: 30)
App.window2.orderFront(sender: nil)
App.window2.setFrameOrigin(NSPoint(x: 300, y: 300))
App.window2.setTitle(NSString(string: "Window 2"))
App.window2.addSubview(App.button)
//App.window.printWindow()
//window.setBackgroundColor(NSColor())
//'UnsafeMutablePointer<Int8>
//UnsafeMutablePointer<UnsafePointer<CChar>?>
//return
return NSApplicationMain(CommandLine.argc, CommandLine.unsafeArgv.pointee)
}
}下の2行を追加しています。
1 App.label.frame = .init(x: 20, y: 20, width: 200, height: 32)
この行がないと、TextField が表示されない。
2 let image = NSImage.image(named: "Dummy")
この行がないと、Button 生成でコアダンプが起きる。
App.button の前に必要。

}１ TextField や Button は frame 設定がないと表示されない。
２ TextField の文字は text では表示されない。stringValue を用いる。
これで準備が整ったので、NSWindowTest と HelloWorld を実行します。
swift run NSWindowTest
swift run HelloWorld
NSWindowTest は実行できますが、HelloWorld ではコアダンプが起きます。
これは、ビルドされた実行ファイルがある場所に、gorm ファイルを含むResources
がないために起こっています。
この project site の最初に書いてあるように、Resources(NSWindowTest か HelloWorld のいずれか) を .build/debug にコピーします。（一度 swift run を実行しないと .build ディレクトリは作成されない。）今のところ、プログラムの中でコピーする方法が分かりません。
これで、 swift run を実行をすれば、正しく動作するはずです。
gorm ファイルのメニューも表示されます。
HolloWorld では、ボールドフォントのサイズ設定を行っています。
Lubuntu のシェルからの実行では、フォントが見つかりません。
/System/bin/startgsde を実行し、GWorkspace の Terminal から実行します。
