How to switch between multiple .xcassets files

Question

We have 3 targets for 3 different apps offering similar sets of features but different UI. all these 3 targets are having different .xcassets files. But now as per Apple 4.3 guideline, they are asking us to create one container and handle different UI from the same container.

Now as we already have different image assets files for different targets, how can I programmatically switch between different .xcassets files.

Why not put them all into one `.xcassets` file and set the device usage of each asset? — trojanfoe, Feb 18 '19 at 07:21
At the moment I have different images with same name in every xcassets file. Any way I don't want to handle multiple conditions while assigning every image, rather I would prefer to load specific xcasset file on load. — Praful Kadam, Feb 18 '19 at 07:26
you can directly access the images from `.xcassets`, you just have to check for target you are using. — Jarvis The Avenger, Feb 18 '19 at 07:26
@PrafulKadam yeah, even I am also using a similar way to access images from `xcassets` — Jarvis The Avenger, Feb 18 '19 at 07:27

You can have multiple xcassets for multiple targets, let's say you have A, B, C target and have three different xcassets for each target, you can solve this issue with two ways:

Add images with the same name for different targets and access the images directly. Xcode will run time access specific xcassets images.
Add checks for different targets at the time of accessing images

Coding Example:

if target == "A" {
   let imageView = UIImageView(image: UIImage(named: "firstImage"))
}
if target == "B" {
  let imageView = UIImageView(image: UIImage(named: "secondImage"))
}
if target == "C" {
  let imageView = UIImageView(image: UIImage(named: "thirdImage"))
}

I have different images with same image name like 'firstImage' in all xcassets. – Praful Kadam Feb 18 '19 at 07:56
@PrafulKadam Then you will have to add a check for targets. – Jarvis The Avenger Feb 18 '19 at 09:13
@JarvisTheAvenger can u tell how to access target in view controllers i.e can u tell main declaration of target variable which u r using in above example? – jayant rawat Sep 23 '20 at 11:54
@jayantrawat You can use the user-defined section under the project's build setting to add target based variables to distinguish between targets. – Jarvis The Avenger Sep 23 '20 at 12:56

First I have created multiple image version is same xcasset file and then I created an extension for UIImage and wrote convenience initializer where I check the current target and assign image name accordingly

extension UIImage {

convenience init?(editableNamed: String) {
    let newName = appDel.target != "target1" ? editableNamed : "\(editableNamed)_target1"
    if (UIImage(named: newName) != nil) {
        self.init(named: newName)
    }
    else {
        self.init(named: editableNamed)
    }
}

So whenever I assign image like

cell.imgCheck.image = UIImage(editableNamed: "iconCheck")

It checks the current target and then assigns appropriate image from xcasset file.
