Add middle-button panning support to Sketch to match Figma, Fusion 360, etc.
-- Make Sketch use the middle mouse button for dragging like Figma, Fusion 360, etc.
local middleMouseDown = false
-- Function to handle the middle mouse down event
local function middleMouseDownHandler(event)
if event:getType() == hs.eventtap.event.types.otherMouseDown then
if event:getProperty(hs.eventtap.event.properties['mouseEventButtonNumber']) == 2 then
middleMouseDown = true
-- Simulate holding down the space bar
hs.eventtap.event.newKeyEvent(hs.keycodes.map['space'], true):post()

How to accomplish a long-pressable button in SwiftUI with two different techniques. The first just uses SwiftUI but due to the simultaneous gesture requirement you also have to ensure both don't fire concurrently. The second uses UIKit and wraps UIButton and UILongPressGestureRecognizer which natively handles this behavior.
import SwiftUI
// PURE SwiftUI way with State tracking to prevent double events
struct ContentView: View {
@State private var ignoreTapEvent = false
var body: some View {
Button {
guard !ignoreTapEvent else {
