How do I set a UInt32 to it's maximum value
There's a macro UINT32_MAX defined in stdint.h which you can use
#include <stdint.h>uint32_t max = UINT32_MAX;More about the relevant header <stdint.h>:

The maximum value for UInt32 is 0xFFFFFFFF (or 4294967295 in decimal).
sizeof(UInt32) would not return the maximum value; it would return 4, the size in bytes of a 32 bit unsigned integer.
Just set the max using standard hexadecimal notation and then check it against whatever you need. 32-bits is 8 hexadecimals bytes, so it'd be like this:
let myMax: UInt32 = 0xFFFFFFFFif myOtherNumber > myMax { // resolve problem}
