YOUR FIRST GAME
Set up S2Arm on Mac for iPhone or iPad
Prepare Xcode, import your own game, build for iPhone or iPad, then install and finish the resource import in seven steps.
You confirm each step yourself. We cannot detect your device or game. Skipping does not count as completion.

This route uses the graphical launcher on an Apple silicon Mac. Start with the materials checklist if you do not yet have your own game files and keys.
STEP 1 OF 7
Step 1: Install the official launcher
Download S2Arm-mac-arm64.dmg from the official v0.2.8 release, not an old ZIP or Source code. This route follows v0.2.8; read the release notes if choosing a later version.
Open the disk image, follow its installation layout to place S2Arm in Applications, then open the app. For a normal first-open confirmation, check that this is the official file you downloaded. For a damaged or explicitly blocked file, verify the source and integrity; do not broadly disable system protections.
Success check: The welcome page and environment preparation items appear.
STEP 2 OF 7
Step 2: Prepare Xcode and build tools
Opening S2Arm does not mean the tools for building are ready.
- Install full Xcode, not only Command Line Tools.
- Open Xcode once and complete its initial setup.
- Return to S2Arm and prepare the Metal components requested. This phone route also needs the iOS platform components.
- Run the environment check again. Resolve explicit version or target requirements.
macOS 15 is the app's declared minimum, not a guarantee that it can install every current Xcode version. Stop at preparation if your system cannot support the required toolchain. Versioned toolchain
Use a local APFS game library with sufficient space, outside cloud sync folders. For external storage, follow the checks and storage guidance.
Success check: The requirements to build for a phone pass. Account setup can wait until installation.
STEP 3 OF 7
Step 3: Import your keys and game
Select your own prod.keys, then Add Game. Choose the base NSP/XCI or the folder containing the base and any updates or DLC you have.
If macOS requests folder access, allow the access needed for your chosen files. A denied folder permission is not a keys problem.
Wait for import, check the game and version in the library, and inspect failed-item details. See import errors when needed.
Success check: The game appears without a missing base or required-content notice.
STEP 4 OF 7
Step 4: Build for iPhone or iPad
Select the game and choose iPhone / iPad as the build target. Follow the target-device prompts, confirm storage and start. Choose only the target you need for the first run.
Keep power connected and prevent sleep. Use stages, completed amounts and warnings to judge progress; another computer's demonstration time is not a reliable limit.
Success check: The phone build finishes. Resolve precompilation warnings using update and rebuild guidance before treating it as ready.
STEP 5 OF 7
Step 5: Prepare the account and device
- In Xcode's Apple Accounts settings, add your own account and wait for its teams to appear.
- Connect the target phone or tablet with a data cable, unlock and complete trust prompts.
- If it is not detected, open Xcode's device management and complete pairing. Depending on version, this may be Devices and Simulators or Device Hub. Finder detection does not prove Xcode pairing is complete. User report
- Enable Developer Mode when prompted, restart and confirm. Pairing may be needed before the switch appears. Apple guidance
- Return to S2Arm's installation check. If signed in but missing a team, follow the page's solution / helper project, choose your Personal Team in Xcode and run it as instructed. A missing team does not require rebuilding the game.
Success check: S2Arm detects the connected target and has the signing requirements ready. See device connection troubleshooting if not.
STEP 6 OF 7
Step 6: Install and finish resource import
Use Install to iPhone / iPad and follow the prompts. Keep the phone unlocked and connected. Signing, app installation and resource transfer are consecutive but distinct stages.
If asked to open the app manually, open S2Arm on the phone, select the game and keep it in the foreground until import finishes. Normal launcher installation handles transfer; do not switch to manually copying folders in Finder by default.
Success check: The game is selectable on the phone and no longer says it needs game data or is still importing. Otherwise see empty library and resources.
STEP 7 OF 7
Step 7: Launch and check input
Launch the game, reach an interactive scene and check that input responds. A visible library does not prove the game runs. For a crash or rendering problem, record the exact scene and use the problem report.
For a launch crash on an older runtime, v0.2.8 fixes missing graphics functions used by some OpenGL games. See the update and runtime checks; verify the installed phone version and do not assume every crash shares this cause. The Windows Impactor and library-encoding fixes do not replace this route's Xcode steps.
Success check: You reach a playable scene and can interact. Continue with backups, renewal and the next game. Do not uninstall the phone app as the first response to a later issue.
