Mastering AI UI: Building a Reusable, Animated Confidence Bar with Swift 6 and SwiftUI

In the world of AI-powered applications, delivering a result is only half the battle. The other half? Winning the user's trust. When an AI model makes a prediction, it isn't just "right" or "wrong" - it operates within a spectrum of certainty. If your app tells a user their medical scan looks clear or their financial trend is bullish without explaining how sure it is, you’re operating a black box. To bridge this gap, we use the Confidence Bar. This UI component doesn't just show data; it communicates the "thought process" of your model through smooth, real-time animations.
