Swift non Inclusive Range with Double Dot

Question

for i in 0..100 {
    println("\(i)")
}

I different types of errors depending on the location of the statements:

• Operator is not a know
• Use of unresolved identifier '..'
• Braced block of statements is an unused closure

Answer 1

The half-closed range operator has been changed to '..<' since Xcode beta 3. See release doc here https://developer.apple.com/swift/blog/?id=3

The error message will disappear if you do this:

for i in 0..<100 {
    println("\(i)")
}
