There are buttons present in apps, such as TextEdit where the sides of adjacent buttons are joined together. Does anyone know how I could replicate this visual? I'm working in SwiftUI on MacOS, and answers for MacOS 10 & 11 would be appreciated.
I don’t think that’s possible in SwiftUI, unless you want to build it from scratch. What you’re seeing in TextEdit is an NSSegmentedControl that allows multiple selection: https://developer.apple.com/design/human-interface-guidelines/macos/selectors/segmented-controls/
In SwiftUI, segmented controls are made using Picker, which doesn’t allow multiple selection. Your best bet is to wrap NSSegmentedControl in an NSHostingView.
