How to check if device is an iPad or iPhone not working

Question

I am currently updating an app and I need to know whether the app is being used in an iPad or not.

I checked online and I found the code below. I used the iPad simulators in Xcode and ran both if statements. but whenever I run the code, nothing happens (the print message does not print) does this code work with simulators or am I doing something wrong?

When I check if it is UIUserInterfaceIdiom.phone the print statement executes, but I am using an iPad in the simulator.

if(UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiom.pad){
        print("This is an iPad")
        redoButton.layer.position.y -= 500



    }

if UIDevice.current.userInterfaceIdiom == .pad{
        print("iPad True")
    }

Thank You

Answer 1

if UIDevice.current.userInterfaceIdiom == .pad {
    print("iPad")
}else{
    print("not iPad")
}

But you need to make your app a universal app.
