iOS: Performance of reloading UIImage(name:...) -

i have tableview , each row has icon. 90% of rows have same icon.

in cellforrowatindexpath method load image assets folder this:

var cellimage = uiimage(named: "myimage") 

does pose performance problem? os somehow smart enough it's same image each time? better if loaded image once , saved in class variable , assigned each time?

uiimage's named: api does kind of caching.

if @ uiimage's documentation, states:

use init(named:in:compatiblewith:) method (or init(named:) method) create image image asset or image file located in app’s main bundle (or other known bundle). because these methods cache image data automatically, recommended images use frequently.
