// As written here, systemImageNamed is an iOS 13 feature. It is available in the UIKitCore framework publically. You are welcome to use your own images just as usual. Make sure you set them up with UIImageRenderingModeAlwaysTemplate to allow proper coloring.

[continueButton.layer setCornerRadius:15]; // Set your button's corner radius. This can be whatever. If this doesn't work, make sure you make setClipsToBounds to YES.
[welcomeController.buttonTray addButton:continueButton];
//The caption text goes right above the buttons, sort of like as a thank you or disclaimer. This is optional, and can be excluded from your project.
