Lic - easy, safe object slicing for Swift

Summary

Lic is a μ-framework that makes getting slices of arrays and strings in Swift 2 safe and easy:

[0,1,2,3][1, -1]            // => ArraySlice([1, 2])
"Hello"[-1000, nil]         // => "Hello"
[1,2,3,4,5,6,7,8][1,5][2,3] // => ArraySlice([4])

Lic has no dependencies, not even Foundation.

Range Free Slices

To make a slice, you must give two indexes, indicating the start and end positions where the slice will be produced. Lic tries to make sense of the indexes following these rules:

• a negative index indicates a position counted in the reverse direction
• nil is equivalent to the start or end index
• an out-of-bound index is treated as the same as start or end index, depending on which bound it goes beyond
• if the start index ends up at a position after the end index, Lic returns the empty value

When it comes to slicing, your ranges are always safe and accepted.
