Question

This should be portray asset image when "ask" button pressed. i wrote all things that i knew but it still show like that

Answer 1

In the image you posted, you defined:

@IBOutlet var ImageView: [UIImageView]!

but then you try to reference it with a lower-case i :

imageView = ballArray...

As a side note, even correcting to an upper-case i you'll get an error, because you've defined ImageView as an array of image views, but you're code trying to assign one image view to it (from your ballArray ).
