In C / Objective-C it is possible to find the minimum and maximum value between two numbers using MIN and MAX macros. Swift doesn't support macros and it seems that there are no equivalents in the language / base library. Should one go with a custom solution, maybe based on generics like this one?

Python's built-in min() and max() functions come in handy when you need to find the smallest and largest values in an iterable or in a series of regular arguments.
MAX and MIN operate on columns that contain character, graphic, numeric, date/time, and binary data (except for binary large object, or BLOB, data). The parentheses are required.
Sometimes it is also useful to use the min and max to calculate the range of a dataset. The range is a numerical indication of the span of our data. To calculate a range, simply subtract the min (13) from the max (110).
min and max are defined in Swift:
func max<T : Comparable>(x: T, y: T, rest: T...) -> T func min<T : Comparable>(x: T, y: T, rest: T...) -> T and used like so:
let min = min(1, 2) let max = max(1, 2) See this great writeup on documented & undocumented built-in functions in Swift.
