#Instance methods

times

• times (call: () -> ())
• times (call: (T) -> ())

Calls call for each value in the range self.

Example

var count = 0
(2..4).times{ count++; return }
println(count)
// → 2

---

each

• each (call: (T) -> ())

Calls call for each value in the range self.

Example

var items = Int[]()
(0..2).each {
    items.append($0)
}
println(items)
// → [0, 1]

#Class methods

random

• random (from: Int, to: Int) -> Range<Int>

Returns Range with random bounds between min and max (inclusive).

Example

Range.random(min: 5, max: 10)
// → 6..8

#Operators ##Equality

• == <U: ForwardIndex> (first: Range<U>, second: Range<U>) -> Bool

Checks if first and second are the same range:
first.startIndex == second.startIndex && first.endIndex == second.endIndex.
