We are creating a app in landscape mode, but we weren’t told how to change the view in the simulator. The orientation is by default in portrait mode. To change this when the simulator is open, go to to Hardware>Panel>Orientation> Landscape Right to change the orientation.

An easy way to quickly change orientation is by typing CMD + Left or CMD + Right while the simulator is open.

How to add the handy object select button in the XCode toolbar that showed in the video 4:23 (the button that just beside the “Show Standard Editor” button)?

@wwj That should be there by default if you use Xcode 10 (it’s a new feature). Do you have that installed?

7

I am using Xcode 10. However, just like the previous observations(comments) Even after the orientation selected( landscape), when running the simulator the “hit me” button isn’t centered and it’s on portrait view. However, after using CMD right or CMD left, I was able to correct the simulator view.

Hi,

I’m trying to do the first step of adding @IBAction func but I keep getting an message that states “Expected identifier in function declaration” and doesn’t show the showalert in the sentevents.

@csbal90 Do you still have this issue?

I am at the part where you link the button to the function, but when I drag it, showAlert does not show.
