Swift: 判斷 App 是在 iPhone 實體機執行，還是在模擬器中

2017052414:48

#if (arch(i386) || arch(x86_64)) && os(iOS)
...模擬器
#else
...iOS 實體機 
#endif

Detect the watchOS simulator

#if (arch(i386) || arch(x86_64)) && os(watchOS)
...模擬器
#else 
...watchOS 實體機
#endif

Detect the tvOS simulator

#if (arch(i386) || arch(x86_64)) && os(tvOS)
...
#endif

Or, even, detect any simulator

#if (arch(i386) || arch(x86_64)) && (os(iOS) || os(watchOS) || os(tvOS))
...
#endif


Static let isSimulator: Bool = {
    var isSim = false
    #if arch(i386) || arch(x86_64)
        isSim = true
    #endif
    return isSim
}( )


if Platform.isSimulator { 

   print("Running on Simulator") 

} else { 
    // Do the other
}
