ios - Full Screenbackground Image in Swift -

i seek fullscreen background ios project means image should stretch on total background. seek 2 things won't worked out solution.

1)

self.view.backgroundcolor = uicolor(patternimage: uiimage(named: "background.png")!)

this set background image on actual image size , repeat in x , y, not stretch image fullscreensize.

2)

use uiimage , create equal width , height , utilize aspect fill, not give wanted solution , utilize much memory

is there other way done?

so have 2 ways autolayout

1) add-on of inequality constraint shown in images below.

2) or adding leading, trailing space , top, bottom space constraint , centering vertically , horizontally constraints no explicit height nor width constraint.
