If you have set up your UIBarButtonItem with an image in the storyboard  one small hack to change the renderingMode is to add the following code to your viewDidLoad     This way you don t have to resort to adding the entire button and image in code  if let navButton   self navigationItem leftBarButtonItem  let buttonImage   navButton image       navButton image   buttonImage withRenderingMode  alwaysOriginal

Your problem is because of the way the icon has been made - it doesn t conform to Apple s custom tab bar icon specs   To design a custom bar icon  follow these guidelines    Use pure white with appropriate alpha transparency  Don   t include a drop shadow  Use antialiasing     From the guidelines    Something that would be possible looks like this   You can find such icons on most free tab bar icon sites
