UI Design for iOS 16 in Sketch
What is a Variable Color ?
Variable Color allows you to customize the appearance of your icons using a percentage value. This is great for symbols that show a progress such as loading, sound volume, Wifi strength, etc.
How does it work?
Open the SF Symbols application and navigate to the Variable category. You’ll find a new control set for Variable Color. Activate it. Play with the slider to adjust the percentage and watch the layers change opacity.
Background
Combine colors to create a nice background for the user interface.
- Create an Artboard, choose iPhone 13 Pro and add a background color that is neutral and light #CCD9EF.
- Create an Oval (press O) of 500 x 684, colour #E0DCF1. Remove the border, blur 30.
- Put it in the middle of the Artboard.

- Write Cancel and Reset using Expanded Medium 17.
Calendar
We need a calendar. I have already prepared it for you in the asset file, but I still want to show you how to make it.
- Create a rectangle of 350 x 355, color white, opacity 50%.
- Add shadow, color black, Y 10 and blur 30.
- Write a title July 2022 using Expanded Bold 20, color black.
- Write the first letter of the day using Condensed Bold 20, color black.
- Write the number of the day using Regular 15.
Select Date
Select the date and create a connection between the two dates.
- Create a circle 30 x 30 behind 15, color #4AA6F4.
- Duplicate the circle. Place it behind 21.

Layout
Add a location button that will take us to a list of stores to help users find the stores nearby.
- Create a rectangle of 350 x 54, color white, opacity 60%, shadow Y 10 Blur 30.

- Duplicate, change the title to End and the date 21 July 2022.
Price and Rent Now Button
After selecting the date will appear the total rental price. Then the user can click on the Rent Now button to pay.
- Write Total: $900 using Expanded Bold 17, color white. Set auto-width and align text left.
- Create a Rectangle of 186 x 60 , color # 4AA6F4. Add shadow, color # 4AA6F4. Y 10 Blur 30.
- Write Pay Now using Expanded Bold 17, color white. Set auto-width and align text left.
Touch ID Symbol
Let’s add a Touch ID symbol to the Pay Now button to make the design more captivating. While it looks static in the design tool, it’ll be more dynamic in SwiftUI as demonstrated in the SF Symbols App.
- Create a Circle of 50 x 5, color black, opacity 40%, blend mode Overlay.
- Copy the Touch ID symbol and place it on the circle.
- Group them and put them inside the Pay Now button on the left.
