After Moving to SPM, My App Died the Moment It Launched — Reading One dyld Line with Claude Code
Right after moving from CocoaPods to Swift Package Manager, the build passed but the app died on launch. Here is how I traced one dyld line to its cause, the fix, and how to verify it.
The One File I Keep Out of Claude Code's Reach: project.pbxproj
With Xcode project files, the breakage that still opens costs far more than the breakage that refuses to open. Here is what I measured before moving every edit behind a script, and where the line sits today.
Semi-Automating Firebase SDK Upgrades with Claude on Xcode — Implementation Notes from Six Indie iOS Apps
How I used Claude on Xcode integrated into Xcode 16.4 to walk six iOS apps through Firebase SDK 12 to 13 upgrades and finish the CocoaPods to Swift Package Manager migration — with the actual prompts, regression tests, and the judgment calls along the way.
Design Decisions Every Indie Developer Faces When Integrating Claude API into Mobile Apps
The design decisions indie mobile developers hit when integrating Claude API — model selection, async UX, context management, offline resilience, and cost control — with working code and a per-user cost table recalculated for the September 2026 price change.
Building StoreKit 2 × SwiftUI Purchases with Claude Code — The Minimum That Passes Review
Build a StoreKit 2 × SwiftUI purchase flow end to end with Claude Code as your design partner — PurchaseManager, server-side validation, and paywall UI — plus the operational traps Apple's docs skip, like Ask to Buy and late-arriving transactions.
iOS Test Automation with Claude Code — Where XCTest, Swift Testing, and XCUITest Each Belong
How I rebuilt an iOS test suite with Claude Code: where XCTest, Swift Testing, and XCUITest each belong, the pipefail trap that turns failed tests green in CI, and a hook that hands only test failures back to Claude.
Auditing Your Own Code for Required Reason API Declarations with Claude Code
Required reason codes in PrivacyInfo.xcprivacy apply to your own code, not just third-party SDKs. After a wallpaper app of mine was rejected, here is the Claude Code workflow I use to scan Swift sources and match APIs to reason codes before submission.
Fixing Blurry Wallpapers on New iPhones with Claude Code: Safely Growing a Per-Device Resolution Map
Why wallpapers go blurry or letterboxed on brand-new iPhones, and how to collapse scattered device branches into a single source of truth you can extend in one line — walked through as a real Claude Code refactor with before/after code.
Stop Terminology Drift in Localized Apps: A Consistent Localizable.strings Pipeline with the Batch API and a Cached Glossary
Translating UI strings one at a time invites inconsistency. Pair Claude's Message Batches API with a prompt-cached glossary to translate Localizable.strings across 10+ languages consistently, with measured costs and the pitfalls I hit in production.
Clearing Crashlytics 'Missing dSYM' Warnings with Claude Code: A Field Memo
Right after moving Firebase to SPM, my Crashlytics reports stopped symbolicating and showed raw addresses. Here is how I narrowed down the Missing dSYM cause with Claude Code and rebuilt an upload path that does not break again.
Triaging iOS Test Failures Fast: Parsing .xcresult with Claude Code
Xcode 16 deprecated xcresulttool's legacy JSON, changing how you pull test failures out of a .xcresult bundle. Here's how to shape the new test-results format with jq and hand it to Claude Code to pinpoint the cause and a fix, drawn from running six apps in parallel.
Two Weeks of Splitting iOS Work Between Claude on Xcode and Claude Code
I ran Claude on Xcode, which lives in the Xcode sidebar, alongside Claude Code in the terminal across two weeks of real wallpaper-app work. Here is how I ended up dividing the tasks, and the simple rule I use to decide which one to open.
