Create icons for application
Apple requires that you create an app Icon with a 1024x1024 resolution. You can use your favorite photo editor to create the icon but if you are familiar with Photoshop, you can download an example template using the following link.
If you use the template make sure that you add your own icon and export out the image as a .jpg at the 1024x1024 resolution.
You could use Photoshop to create the following images that Apple requires.
We are going to use the following service called App Icon Resizer to convert our image to all the sizes that we will need.
Select the platforms that you want to distribute your application to.
Make sure that you select Download Selected option so you won’t download any unneeded images.
You will get a .zip file that contains all the images, extract out that file with the images by double-clicking on the zip icon.
You will get the following images inside that folder.
Now open up your XCode project and go over to the Asset section to set the icon images.
Select the AppIcon available item.
You will then have to drag over each of the icons into each of the selected areas. This can be a bit tricky if you have not done this before but just keep the following ideas in mind and you will be fine.
1) The red arrow is what the default image size needs to be
2) The yellow arrow is the number of times you have to multiply the default size by
3) The black arrow is where you drag over the icon
In this example, we need two images. Image one would be a 120x120 image and the second one would be 180x180. To find these images select an image and right click on it to get more information.
Click on the More Info: option to view the dimensions of the image.
If the values are correct drag and drop the image into the slot and repeat this process for each of the items.

I always had a passion for the field of STEM (Science, Technology, Engineering, and Math) and I knew I wanted to do something to make a difference in the world. I just didn’t know where to start. I was an immigrant in a new country, grew up in a tough environment, and wasn’t sure how… Read More
