| # The only place the Apple side can actually be checked. | |
| # | |
| # Klibs for iosArm64 / iosSimulatorArm64 cross compile on any host, so a developer on Windows or | |
| # Linux already knows the shared code COMPILES for iOS. What no other machine can do is RUN it: | |
| # `iosSimulatorArm64Test` is disabled off macOS with "simulator tests require macOS", and it reports | |
| # SKIPPED rather than failing, so a green build elsewhere says nothing about iOS behaviour. | |
| # | |
| # That gap matters most for the four platform actuals under the shared data spine. `utcOffset` is | |
| # written to every record, takes part in contentEqualsTo and is validated by Nightscout, and it comes | |
| # from NSTimeZone on Apple and TimeZone.getOffset on the JVM. NumberFormatParityTest and | |
| # SystemTimeZoneTest in commonTest exist to compare them; this job is where they finally execute. | |
| # | |
| # No secrets: nothing is signed, published or uploaded. | |
