NSAlert destructive button

swift cocoa macos-big-sur nsalert

As Big Sur came onto our Macs I noticed that destructive button's text in NSAlert controller are colored in red as shown in picture.

An example from the Apple's Message app

I wasn't able to find a way to bring this feature in my app.

Using the standard addButton(withTitle:) method we haven't any way to set its intent (such as default, cancel or destructive).

Can you give me any hint?

Thanks


Solution 1:

Set the property hasDestructiveAction of the button to true . This property is new in Big Sur.
