Programmatically detect if app is being run on device or simulator

I'd like to know whether my app is being run on device or simulator at run time. Is there a way to detect this?

Reason being to test bluetooth api with simulator: http://volcore.limbicsoft.com/2009/09/iphone-os-31-gamekit-pt-1-woooohooo.html

if anyone is looking for Unity solution i did this, the only way i found how.

using System.Globalization;

public static bool IsArm() {
        return CultureInfo.InvariantCulture.CompareInfo.IndexOf(SystemInfo.processorType, "ARM", CompareOptions.IgnoreCase) >= 0;
    }

Use this below code:

#if targetEnvironment(simulator)
   // iOS Simulator
#else
   // Device
#endif

Works for Swift 4 and Xcode 9.4.1

From XCode 9.3+ , Swift

#if targetEnvironment(simulator)
//Simulator
#else
//Real device
#endif

Helps you to code against device type specific.

#if TARGET_OS_SIMULATOR

//Simulator

#else

// Device

#endif

Pls refer this previous SO question also What #defines are set up by Xcode when compiling for iPhone

Check if simulator

#if TARGET_IPHONE_SIMULATOR
// Simulator
#endif

Check if device

#if !(TARGET_IPHONE_SIMULATOR)
// Device
#endif

Check for both

#if TARGET_IPHONE_SIMULATOR
// Simulator
#else
// Device
#endif

Please note that you should not ifdef on TARGET_IPHONE_SIMULATOR because it will always be defined to either 1 or 0.

I created a macro in which you can specify which actions you want to perform inside parentheses and these actions will only be performed if the device is being simulated.

#define SIM(x) if ([[[UIDevice currentDevice].model lowercaseString] rangeOfString:@"simulator"].location != NSNotFound){x;}

This is used like this:

SIM(NSLog(@"This will only be logged if the device is simulated"));

TARGET_IPHONE_SIMULATOR is defined on the device (but defined to false). and defined as below 

#if TARGET_IPHONE_SIMULATOR
NSString * const DeviceMode = @"Simulator";
#else
NSString * const DeviceMode = @"Device";
#endif

Just use DeviceMode to know between device and simulator

You can use the TARGET_IPHONE_SIMULATOR preprocessor macro to distinguish between device and simulator targets.
