Could the app that's 32 bit run on 64 bit, iPhone 5S?

If doing this, $(ARCHS_STANDARD_32_BIT), like answers here suggested, Arm64 architecture in xcode 5.1

Will these 32 bit app be compatible with 64 bit and run well on iPhone 5S or even later?

Yes they will run on an iPhone 5S. The iPhone 5S will load the 32-bit framework into shared memory on the device, and run the app using that.

But it is worth while supporting both 32-bit and 64-bit architectures to reduce the memory usage your app consumes on a 64-bit device - even if you're not using any 64-bit specific features.
