Found the reason, the same file name have a "/" in it, which cause the save progress thought it finished, but maybe saved to some invalid path? Don't know, but that's the reason.

Same here, [GKLocalPlayer saveGameData: withName: completionHandler:] reported successed [GKLocalPlayer fetchSavedGamesWithCompletionHandler:] got 0 data Tried to call “[GKLocalPlayer.localPlayer fetchSavedGamesWithCompletionHandler:nil];” first, still the same. Try to make thread wait 2sec before fetch, still the same.

Any one got any idea? I got a simplest sample here, followed the code from this video: https://developer.apple.com/videos/play/wwdc2021/10081/ But still not working. #import "AppDelegate.h" #import <GameController/GameController.h> @implementation AppDelegate - (void)applicationDidFinishLaunching:(NSNotification *)aNotification { // Insert code here to initialize your application [ [ NSNotificationCenter defaultCenter ] addObserver:self selector:@selector( controllerDidConnect: ) name:GCControllerDidConnectNotification object:nil ]; [ [ NSNotificationCenter defaultCenter ] addObserver:self selector:@selector( controllerDidDisconnect: ) name:GCControllerDidDisconnectNotification object:nil ]; [ GCController startWirelessControllerDiscoveryWithCompletionHandler:^ { NSLog( @"Finished finding controllers" ); } ]; } -(void)controllerDidConnect:( NSNotification * )notification { GCController *controller = notification.object; [ controller.extendedGamepad.buttonA setValueChangedHandler:^( GCControllerButtonInput * button, float value, BOOL pressed ) { NSLog(@"controller Button A pressed."); if ([[[GCController current] physicalInputProfile] isKindOfClass:[GCDualSenseGamepad class]]) { GCDualSenseGamepad *dualSense = (GCDualSenseGamepad *)[[GCController current] physicalInputProfile]; GCDualSenseAdaptiveTrigger * rightTrigger = dualSense.rightTrigger; [rightTrigger setModeFeedbackWithStartPosition:0 resistiveStrength:0.9]; } } ]; [ controller.extendedGamepad.buttonB setValueChangedHandler:^( GCControllerButtonInput * button, float value, BOOL pressed ) { NSLog(@"controller Button B pressed."); if ([[[GCController current] physicalInputProfile] isKindOfClass:[GCDualSenseGamepad class]]) { GCDualSenseGamepad *dualSense = (GCDualSenseGamepad *)[[GCController current] physicalInputProfile]; GCDualSenseAdaptiveTrigger * rightTrigger = dualSense.rightTrigger; [ rightTrigger setModeVibrationWithStartPosition:0 amplitude:0.5 frequency:0.03 ]; } } ]; [ controller.extendedGamepad.buttonX setValueChangedHandler:^( GCControllerButtonInput * button, float value, BOOL pressed ) { NSLog(@"controller Button X pressed."); if ([[[GCController current] physicalInputProfile] isKindOfClass:[GCDualSenseGamepad class]]) { GCDualSenseGamepad *dualSense = (GCDualSenseGamepad *)[[GCController current] physicalInputProfile]; GCDualSenseAdaptiveTrigger * rightTrigger = dualSense.rightTrigger; [ rightTrigger setModeOff ]; } } ]; } -(void)controllerDidDisconnect:( NSNotification * )notification { } @end

Yes, I've debugged it step by step, and checked the value one by one. One thing I've notice is that after the setModeWeaponWithStartPosition (or setModeFeedbackWithStartPosition), the mode is still 0 (GCDualSenseAdaptiveTriggerModeOff), I don't know if this is normal. By the way: MacOS: Sequoia 15.2 Chip: Apple M1 Ultra If it metters.

Found out why. We need to set the Skip install for all the static libraries.
