Requirements: • The calculator should support 4 basic arithmetic operations: + – * and / • The calculator will operate on hexadecimal numbers, not decimal numbers • The calculator only needs to operate on unsigned integers (i.e. UInt). You do not need to consider negative numbers or fractions. • The calculator should support the 16-digit hexadecimal numbers (i.e. The range of the numbers is from 0 to FFFF FFFF FFFF FFFF). Prevent the user from entering a number that is greater than FFFF FFFF FFFF FFFF. • The calculator should handle overflow and underflow gracefully. The app must not crash. • The calculator should handle division-by-zero error gracefully. The app must not crash. • The calculator should be able to support most of the devices and orientations. If it does not support the old devices earlier than iPhone 6, it is okay.
