Picker View for Time Durations Link to heading

In my Timer app, I needed a Picker View for taking the timer interval from the user. Sadly, at this moment SwiftUI does not come with a built in View that I needed for my use case. However, SwiftUI does provide the building blocks to create such a view.

Change the Back Button’s Icon Link to heading

If you have used the default Settings App that comes with iOS, you are most likely to be familar with the back button with the “less than” symbol “< Back” on the top left of your iOS devices screen (in the navigation bar). It’s something we have gotten very used to, thanks to it being implemented in not only the first party apps by Apple, but also the innumerous 3rd party apps that use the NavigationStack and related API’s.

Making a Dynamic Button Link to heading

If you have noticed, the play button on most media players changes to pause once the media starts playing and vice versa. This is a behavior, I also needed in one of my apps that I was building.

It’s a functionality pretty staright forward to achieive in SwiftUI.

Progress View Ring Link to heading

I was building a Timer app and needed a visual indicator to display the the amount of time left while the countdown was running. A circular progress bar similar to the fitness/activity rings of Apple Watch made the most sense. Sadly, Apple currently doesn’t provide a good API to use such a view in your own apps. However, building such a View in SwiftUI is pretty simple.
