in app used uicollectionview how make difference between 2 cell same in iphone models. , auto layout turned on tried many things issue not resolved app looks perfect in iphone 5s shows more difference between 2 cells in iphone 6s , 6s plus.enter image description here

you need calculate cell dynamically according screen size. have faced such situation , fixed it. can try this, might you...

- (cgsize)collectionview:(uicollectionview *)collectionview layout:(uicollectionviewlayout*)collectionviewlayout sizeforitematindexpath:(nsindexpath *)indexpath { return cgsizemake(width, height); } 

get width , height

-(void)getdynamiccellsize {  width = (screen_size.width - 50)/3; height = (screen_size.height - (135+self.tabbarcontroller.tabbar.frame.size.height)-29)/3; } // 135 means navigation bar height + segment control (i have in design)   cgfloat width, height;// declare globally 

call getdynamiccellsize method in viewwillappear or didload

or

use code in sizeforitematindexpath method in 'swift'

let flowlayout = collectionviewlayout as! uicollectionviewflowlayout let cellwidth = (cgrectgetwidth(collectionview.frame) - (flowlayout.sectioninset.left + flowlayout.sectioninset.right) - flowlayout.minimuminteritemspacing) / 2 return cgsize(width: cellwidth, height: cellwidth) 

happy coding...
