Programmatically detect if app is being run on device or simulator

Question

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:

Answer 1

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.

Answer 2

Use this below code:

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

Works for Swift 4 and Xcode 9.4.1

Answer 3

From XCode 9.3+ , Swift

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

Helps you to code against device type specific.

Answer 4

#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

Answer 5

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;
    }

Answer 6

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