Automatic change of images after a time interval?

Question

Apple Xcode

Good day everyone! Please help me solve the following question in swift. In xcode, I brought out an imageView controller in which you need to implement a change of images after a time interval. The bottom line is this: when the user clicks on the controller, the original image changes to another, and after 24 hours the original image returns. An hourly counter, such as 24h, 23h, etc., should be placed next to the images. Help me please!
