ObjC to Swift : [NSArray enumerateObjectsUsingBlock:]

Objective-C

NSArray * array = @[ obj0, obj1, ... ];

[array enumerateObjectsUsingBlock: ^( id object,
                                      NSUInteger index,
                                      BOOL * stop )
{
    // do some stuff for each "object" at "index"
}

Swift 2.0 (using "object" and "index" inside the loop)

let swiftArray: Array = [ obj0, obj1, ... ]

for ( index, object ) in swiftArray.enumerate()
{
    // do some stuff for each "object" at "index"
    // no explicit "stop" parameter ...
}

Swift 1.2 (using "object" and "index" inside the loop)

let swiftArray: Array = [ obj0, obj1, ... ]

for ( index, object ) in enumerate( swiftArray )
{
    // do some stuff for each "object" at "index"
    // no explicit "stop" parameter ...
}

Swift (using only "object" inside the loop)

for object in swiftArray
{
    // do some stuff for each "object"
}

Swift (using no object information inside the loop)

for _ in swiftArray
{
    // do some stuff swiftArray.count times
}
