I used the accepted answer to draw lines in a Tic Tac Toe game when one of the players won. Thanks, good to know that it worked. Unfortunately, I ran into some problems getting it to work on different sizes of iPhones and iPads simultaneously. That's probably something that should have been addressed. Basically what I'm saying is that it might not actually be worth the trouble of all that code, depending on your case.

My alternate solution is to simply make customized, better looking line in Photoshop and then load it with UIImageView. For me this was MUCH simpler, runs better, and looks better. Obviously it really depends on what you need it for.

Steps:

1: Download or create an image (preferably saved as .PNG)

2: Drag it into your project

3: Drag a UIImage View into your storyboard

4: Click on the Image View and select the image in the attributes inspector

5: Ctrl click and drag the Image View to your .swift file to declare an Outlet

6: Set the autolayout constraints so it works on ALL devices EASILY

Animating, rotating, and transforming image views on and off the screen is also arguably easier

To change the image:

yourImageViewOutletName.image = UIImage(named: "ImageNameHere")
