Have you checked: https://developer.apple.com/library/ios/documentation/AudioVideo/Conceptual/CameraAndPhotoLib_TopicsForIOS/Articles/TakingPicturesAndMovies.html
If you have problem translating Objective-C code to Swift, there are online converter tools. Search for "obj-c to swift converter". Or maybe you should search for tutorials written in Swift: "ios camera tutorial swift".
