A beta-SDK build can reach TestFlight, but it can't reach review
Builds made with a beta Xcode can be distributed through TestFlight, but they cannot be submitted for App Store review. Here is how to check which SDK produced your build, and how to protect your release profile in eas.json.
August 31 Means Something Different Depending on Whether You Plan to Ship an Update
Two separate conditions land on Google Play's August 31 date: API 36 to submit an update, and API 35 to stay discoverable to new users. Here is how I sorted six apps, and who actually gets the extension form.
Three conditions that make Play Policy Insights report nothing on an Expo project
Google Play now ships an open-source policy auditing skill. Running it against an Expo-shaped project, one directory argument moved the result from five detected data categories to zero. Here is when the scan actually reaches your code, and where its output should not be trusted.
Version code 1 has already been used — who owns that number, app.json or EAS?
When a Play upload stops on versionCode, check where the number actually lives before bumping it. A one-command way to tell whether app.json, EAS, or build.gradle wins.
The three places I had to fix before a Rork project actually targeted API level 36
My app.json said targetSdkVersion 36. The value my build actually read was 35. Here is the script that reports the effective value, and how I split my apps between raising, leaving alone, and requesting an extension.
Write .gitignore Before You Run git init on an Exported Rork Project
Running git init on a freshly exported Rork project puts your signing keys and .env straight into history. I measured what gets committed when the ignore file comes first versus last, and which exclusion patterns actually work.
When an Expo UI drop-in swap actually removes a dependency
Expo UI went stable in SDK 56 with drop-in replacements for eight community packages. Swapping one import does not always shrink your dependency list. Here is how to decide which swaps actually pay off, straight from the dependency graph.
My chart broke on day one, not at scale
A line chart that vanished for anyone with only a few days of data. The cause was a zero-height Y axis turning coordinates into NaN. Here is the measured behavior and the small normalization layer that fixed it.
Find the Code That Trips App Store 2.5.2 Before You Submit
If a remote value can change what your app does, Guideline 2.5.2 may apply. Here is where the line actually sits, plus a script that surfaces the risky paths in your repo before submission.
TestFlight External Testing or Phased Release: Where a Solo Developer's Time Actually Pays Off
When you ship a Rork-built app to other people, you can recruit external testers or let a phased release absorb the risk. Here is how I split my limited time between the two, based on where distribution actually stalls and which three areas still deserve pre-release checks.
Your lockfile's dev/prod split won't tell you which licenses your app must credit
A record of classifying every dependency in a production project to decide what belongs on an app's license screen, and where the copyleft findings and the actual shipped artifact turned out to disagree.
Four Countries, Not the World: Checking Which of My Six Apps the September 30 Deadline Actually Touches
Android developer verification goes live on September 30, 2026 in Brazil, Indonesia, Singapore, and Thailand. Here's how to decide from your own install data whether that date is urgent for you, and what actually blocks indie developers.
