回答1:

the Wikitude SDK only works on an actual iOS device, the simulator has no support for the camera and the necessary sensors (accelerometer, magnetometer).

Please try building and deploying on an actual iOS device, then everything should work as expected.

This is an old post but I didn't find a positive answer. Actually, I found a way to make it possible to compile in Simulator.

First of all, I edited the class (both h and m) with the Wikitude implementation and work with conditionals: it loads an interface and implementation when it's not a Simulator and it loads another interface and implementation when it's a Simulator:

Example.h

#import <UIKit/UIKit.h>
#import "Example.h"

#if !TARGET_IPHONE_SIMULATOR
#import <WikitudeSDK/WTArchitectView.h>

@interface Example : UIViewController <WTArchitectViewDelegate>
{
    WTArchitectView *_architectView;
}

@property (nonatomic, strong) WTArchitectView *architectView;

@end
#else
@interface Example : UIViewController {

}

@end
#endif

Example.m

#import "Example.h"

#if !TARGET_IPHONE_SIMULATOR
@interface Example () {
}

@end

@implementation Example // implementation for devices
.
.
.
@end
#else
@interface Example ()

@end

@implementation Example // implementation for simulator
.
.
.
@end
#endif

To toggle between compiling on the simulator and on devices, you just have to deactivate or activate the WikitudeSDK.framework for the current target:

1) Choose the WikitudeSDK.framework from the "Project Navigator" on the left panel.

2) Deactivate it for the current target using the "File Inspector" on the right panel.

It worked for me.

Best regards!
