S2Arm cannot detect your iPhone or iPad

1. Connect only the target device with a data-capable cable, directly to the computer if possible.
2. Unlock it, stay on the home screen and complete the trust prompt for your own computer.
3. Refresh the installation checks in S2Arm and look for the actual device name. A manually selected model is not proof of detection.

Open Apple Devices. If missing, use Apple's official guidance to install a supported version. Where the launcher supports your existing iTunes setup, follow the actual check; do not install every Apple app by default.

• Apple Devices cannot see it either: Check the cable, trust prompt and Apple device support first. Rebuilding the game will not fix that connection.
• Apple Devices sees it, but S2Arm reports a missing service: Check the launcher version. #424 concerned a false detection failure with the Store version of Apple Devices. v0.2.3 changed detection to check the actual connection channel instead of only the old service name.
• A newer version still fails: Record the environment-check result and error code. Do not blindly add command-line device tools from an old thread.

The #424 release fix is documented, but this guide does not have the reporter's final confirmation on the fixed build. It is not a site-tested success.

1. Connect and unlock the device.
2. Open Xcode device management, which may be Window → Devices and Simulators or Device Hub, depending on version.
3. Select the device, complete pairing / trust / preparation and wait until outstanding device actions finish.
4. Enable Developer Mode if requested, restart and confirm, then check S2Arm again.

The #459 reporter could already see an iPad in Finder, but S2Arm only detected it after Xcode preparation. This shows the states can differ, not that opening Xcode once fixes every iPad.

If Developer Mode is not visible, begin device pairing first. Apple's guidance explains that the option may not appear before pairing.

Check the selected device rather than only the button. v0.2.6 records a Mac label change to iPad when appropriate. This was a wording fix, not evidence that older versions could never install to iPad.

• Windows Apple error 1100 / sign-in expired: v0.2.8 offers Open Impactor to sign in again. Follow the same-account login recovery; this is not a cable failure.
• Windows cannot read installed games, but the phone already has an empty S2Arm app: v0.2.8 fixes this specific first-install case. Follow the empty-app branch, rather than repeatedly changing pairing settings.
• Resources transferred but no playable game: distinguish transfer from phone-side import in empty library and resources.

Success check: The installation screen lists the device actually connected and can continue to signing checks. Detection is not signing success; 9401 has its own guide.
