Build a SwiftData Debugger and State Inspector
The Problem
macOS/iOS developers using SwiftData face silent UI refresh failures after model writes, with no built-in diagnostics in Xcode after two years since SwiftData's introduction in iOS 17 (2023). Over 14 million active iOS developers worldwide rely on SwiftUI/SwiftData stacks, spending on devtools like proxies and inspectors. Current spend averages $10-100 one-time or $99+/month on partial solutions without SwiftData-specific state inspection.
Core Insight
Unlike DataScout's basic visualization or Xcode's generic tools, this provides deep SwiftData state inspection, real-time diagnostics for write-to-UI refresh failures, relationship tracing, and error monitoring—filling the gap in specialized persistence debugging.
- Target Customer
- Solo indie iOS/macOS developers building SwiftUI apps with SwiftData persistence (est. 500k+ active, part of 14M iOS devs), frustrated by blind debugging of UI non-refreshes post-writes; market growing with SwiftUI adoption.
- Revenue Model
- One-time purchase at $19.99-$29.99, tiered above DataScout ($9.99) but below subscriptions like Bugsee ($99/mo), with pro add-ons for teams; freemium trial to capture indie hackers.
Competitive Landscape
$9.99 one-time purchase
While it offers live updates and #Predicate filtering for SwiftData stores, it lacks advanced state inspection for silent UI refresh failures after writes. No mention of diagnostic tooling for troubleshooting persistence issues without UI refresh.
Free (included in Xcode)
Provides general debugging like breakpoints and variable inspection but has no specialized tooling for SwiftData persistence or UI refresh issues post-writes. Developers must rely on manual Instruments profiling without real-time SwiftData state visibility.
Free (included in Xcode)
Excels in memory and performance profiling but fails to provide SwiftData-specific state inspection or diagnostics for silent UI non-refresh after model writes. Lacks entity relationship navigation or real-time error monitoring for SwiftData stores.
$14.99 one-time purchase (historical; current may vary)
Focuses on live UI view inspection and layer hierarchies but does not address data persistence layers like SwiftData, missing diagnostics for model write failures impacting UI refreshes.
Starts at $99/month
Offers crash reporting and session replays but provides no dedicated SwiftData debugging or state inspection for persistence-related UI refresh problems.
