You'll need to turn on Debug Preview: right-click on the live preview play button and select "Debug Preview" from the popup.

How to print () to Xcode console in SwiftUI ?, Try right-clicking on the live preview play button and selecting 'Debug Preview from the popup. The print function prints messages in the Xcode console when debugging apps.

Debug preview doesn't show print in console. I run in the simulator or device.

I have the same problem as @Luko . My Xcode 12 still won't print, even in Debug Preview mode, and even when I use the tips from Building SwiftUI debugging utilities | Swift by Sundell

Print isn't even working for me when I'm running from the simulator, which is weird because it used to work before for me.
