Build a SwiftData state inspector for iOS and macOS devs
The Problem
iOS and macOS developers using SwiftData face silent UI refresh failures without diagnostic tooling from Apple, forcing app restarts or blind debugging. Discussions on Swift Forums highlight active demand for dedicated SwiftData debugging tools, with developers building prototypes due to gaps in official support. Existing tools like embeddable inspectors exist but are limited, and general iOS debuggers do not target SwiftData state inspection specifically.
Core Insight
Standalone SwiftData state inspector that provides non-embedded, runtime diagnostics for model containers, queries, and UI refresh issues—filling gaps in embeddability requirements, SwiftData specificity, and lack of Apple's tooling.
- Target Customer
- Solo indie iOS/macOS developers and small teams building SwiftUI apps with SwiftData (released 2023), within the ~1M+ active Apple developers seeking runtime data debugging tools.
- Revenue Model
- $29-$49 one-time purchase, positioned between free open-source options and established iOS debuggers like Spark Inspector at $30, targeting developers willing to pay for specialized, production-safe tooling.
Competitive Landscape
Free (open-source GitHub package)
Requires embedding the package directly into the developer's app, which adds runtime overhead and is not suitable for production builds. Lacks standalone diagnostic capabilities for quick inspections without code changes.
Free beta (as per 2013 review; current pricing not confirmed in results)
Focuses primarily on view hierarchy debugging with 2D/3D visualizations, but does not provide specific tooling for inspecting SwiftData model containers, persistent stores, or query states. No mention of SwiftData support in core features.
$30 (one-time purchase as per 2013 review)
Emphasizes view hierarchy and property inspection for iOS apps, but lacks dedicated support for database introspection like SwiftData stores or SQLite contents. Does not address SwiftData-specific refresh or state issues.
Free (open-source repository)
Limited to remote network and data debugging via Chrome DevTools, with no capabilities for runtime SwiftData model inspection, UI refresh diagnostics, or persistent store visualization.
Willingness to Pay
- $30
Spark Inspector costs about $30 on sparkinspector.com.
