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

From XCode 9.3+ , Swift

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

Helps you to code against device type specific.
