writeSimDefaults function

Future<SimDefaultsResult> writeSimDefaults(SimDefaultsWriteInput input)

Writes an NSUserDefaults value for a given bundle ID on the iOS simulator.

Uses xcrun simctl spawn <device> defaults write <bundleId> <key> -<type> <value>.

Never throws; all error conditions are represented as sealed result cases.

Implementation

Future<SimDefaultsResult> writeSimDefaults(SimDefaultsWriteInput input) async {
  final device = await resolveSimulatorDevice();
  final bundleId = input.bundleId;

  final args = <String>[
    'spawn',
    device,
    'defaults',
    'write',
    bundleId,
    input.key,
    '-${input.type}',
    input.value,
  ];

  final error = await runSimctl(args);
  if (error != null) {
    return SimDefaultsFailed(error);
  }
  return SimDefaultsWritten(key: input.key, value: input.value);
}
