Fixing the "enumerate is unavailable" error in Swift 2.0

[kjmcneish]

The enumerate free function has been removed in Swift 2.0 and replaced with the enumerate method on collections. To fix the error, replace the reference to the free function with a reference to the new method.

For example, the following code, which uses the enumerate free function:

Code: [Select]

for (cornerMatrixIndex, cornerMatrix) in enumerate(cornerMatrices) {
}
Can be changed to this:

Code: [Select]

for (forkPositionIndex, forkPosition) in forkPositions.enumerate() {
}
All the best!
