Real life map+reduce solution
//
// returns the list of different extensions from a bunch of files
//
func differentExtensions(fileNames: [String]) {
// Step 1. Map: process file names list to convert to extensions list
let allExtensions = fileNames.map { $0.pathExtension.lowercaseString }
// Step 2. Reduce: iterate removing duplicates
return allExtensions.reduce([String]()) { (acum, value) -> [String] in

Since it seems XCTAssertNotNil is not working with Swift's optional, this is an alternative method. In order to stop execution when test fails, check XCTestCase's continueAfterFailure property
func XCTAssertOptional(expression: @autoclosure () -> AnyObject?, _ message: String? = nil) {
let evaluatedExpression:AnyObject? = expression()
if evaluatedExpression == nil {
if let messageValue = message {
XCTFail(messageValue)
}
else {
XCTFail("Optional asertion failed: \(evaluatedExpression)")
}

Your XCode project uses a lot of images. Maybe some of them are not used anymore, but which ones?
cd ./Images
for f in *.png; do
fn=`echo "$f" | cut -d'.' -f1`
if ! grep -q @2x <<< $fn; then
if ! $(grep -i -r --include=*.m --include=*.xib "`echo "$f" | cut -d'.' -f1`" ../Classes/ > /dev/null); then
echo $f
fi
fi
done
