Testing on a 32-bit Simulator

  • Set the “Architectures” build setting to armv7, which is 32-bit.
  • Use arm64 for 64-bit, and $(ARCHS_STANDARD) default is probably “64-bit if available, 32-bit otherwise”.
  • According to [Wikipedia], all 32-bit devices have been discontinued, but several older ones target iOS 9 & 10, so anyone supporting iOS 9/10 is implicitly supporting 32-bit devices.
