⚡ Bolt: Optimize array allocations and avoid eager filters#293
Conversation
Replaced `.filter { }.isEmpty` checks with `.contains(where:)` to use short-circuit evaluation.
Replaced `.filter` + `.reduce` with `.lazy.filter` + `.reduce` to avoid creating intermediate arrays.
Replaced `.filter` + `.count` with `.reduce` where `.lazy` cannot be used directly (e.g. string interpolation).
This reduces memory churn and prevents O(N) array copies from executing on the main UI thread in SwiftUI view models and views.

💡 What:
Replaced eager
.filteroperations with.lazy.filteror.reduce, and replaced.filter {}.isEmptychecks with.contains(where:)for short-circuit evaluation.🎯 Why:
To prevent unnecessary intermediate array allocations, reducing memory churn and improving performance, especially in SwiftUI computed properties and views which get evaluated frequently.
📊 Impact:
Reduces memory overhead and avoids O(N) full traversal when checking for existence (short-circuiting). Decreases blocking time on the main UI thread.
🔬 Measurement:
Check memory allocations during UI interactions (e.g., selecting items, opening the menu bar). Observe fewer heap allocations per view redraw.
