Determine if iOS device is 32- or 64-bit

Question

Does anyone know of an easy way to tell if an iOS7 device has 32- or 64-bit hardware? I don\'t mean programmatically, I just mean via settings, model number, 3rd-party app,

Answer 1

I use this in swift 4, not sure if it's the best solution but it works.

   func getCPUArch()
   {
      #if arch(arm)
         print("this is a 32bit system")
      #elseif arch(arm64)
          print("this is a 64bit system")
      #endif
   }
