    Bring macOS app to front when dock icon gets clicked

    Implement applicationShouldHandleReopen in your AppDelegate

    func applicationShouldHandleReopen(_ sender: NSApplication,
                                           hasVisibleWindows flag: Bool) -> Bool {
            // Bring app window when dock icon gets clicked
            if !flag {
                for window: AnyObject in sender.windows {
                    window.makeKeyAndOrderFront(self)
                }
            }

  • macOS app basic entitlements file

    macOS app basic entitlements file

    Recently, I have submitted a macOS app on the app store where I used this entitlements file. This uses sandbox, allowing the app to call API to a remote server and select files from the user computer.

  • SwiftUI combine rectangle and triangle in shape

    SwiftUI combine rectangle and triangle in shape

    SwiftUI combine rectangle and triangle in shape

    Making custom shape is not hard in SwiftUI by implementing func path(in rect: CGRect) -> Path. You just have to draw points in your desired location in 2D coordinate space by path.move() and path.addLine() func, a line will be drawn automatically.

    struct MomentumArrow: Shape {
        
        func path(in rect: CGRect) -> Path {
            var path = Path()
            
            let squareHeight = rect.height * 0.65
            
            // Rect
            path.move(to: CGPoint(x: 0, y: 0))
            path.addLine(to: CGPoint(x: 0, y: squareHeight))
            path.addLine(to: CGPoint(x: rect.width, y: squareHeight))
            path.addLine(to: CGPoint(x: rect.width, y: 0))
            path.addLine(to: CGPoint(x: 0, y: 0))
            
            // Triangle
            path.move(to: CGPoint(x: 0, y: squareHeight))
            path.addLine(to: CGPoint(x: rect.midX, y: rect.height))
            path.addLine(to: CGPoint(x: rect.width, y: squareHeight))
        
            return path
        }
        
    }
