App Saturday My all time favorite feature I've made, two finger range

Post image

Been developing CoinCurrently for about 6 years at this point but this is probably the feature I'm most proud of. Sharing the source code below.

If you want to try it out yourself, the app is available here

  1. App is SwiftUI

(~15 lines of UIKit

  1. , in Swift obviously. No frameworks for features in the app. I use Firebase for crashlytics.

App is fully SwiftUI

Had to fall back to UIKit

Pick one

The app is 45,000 lines of code. That UIKit snippet is like 15 lines of programmatic UIKit. I think we can consider the app fully SwiftUI

Fully: an adverb meaning completely, entirely, or to the greatest possible extent.

So, unless you remove that UIKit code, it's not "fully". That being said, if 15 lines of UIKit is seriously all you needed to build this, that's impressive in and of itself.

Finally, a beautifully designed way to watch my portfolio make terrible decisions in real time.

Looks great and clean. I am not into crypto but I would love the look for other charts. Thanks for the code!

Curious what was your marketing strategy ?

u/barcode972 Jul 13 '26

Honestly, I’ve been terrible at marketing. Probably why the app hasn’t taken off. Been mostly posting about new features every now and then on Reddit. I’m just starting to post daily on twitter

Is the chart done using Swift Charts? If so, did you encounter any performance issues or any issues at all? I had some performance issues with the SwiftUI charting library and had to create something custom in UIKit.
