If answer is yes, what are the frameworks can I use? I'm planning to do an app which records in slow-motion mode because in normal I just can record to max 60fps. Can I do it with swift or do I need to use objective-c? I would like to capture 240fps with slow-motion.

I get 1920x1080 240 fps in ultrawideanglecamera mode. And get that camera with discoverySession method of swift.

I am developing a iPhone application that needs realtime sound processing. What i would like to archive is to get the sound loudness (from the microphone), compare it with a threshold and do some logic based on the loudness level. Is there any library in iOS that would enable me to do this? Does iOS have any built in function that would give me the current sound loudness level?
Thanks!
This SO question looks like a good place to start (it's close enough to be a dupe, maybe, but I figured I'd answer anyway).

I need to implement creating custom gesture(like Gesture Builder in Android) in my iPhone application. So, is there any good tutorial or sample application?.
Thanks
The best thing is to watch the WWDC sessions on gestures. They're free and available through iTunes if you're a registered developer.

I have been looking for while for an 'predictive dictionary' that is used the iPhone and other other phones to increase text input accuracy by suggesting the words.
Does anyone know if such dictionary is available for Objective C/iOS?
Or a way/tools to create one from scratch?
Did you consider using UITextChecker ?

I am working on an app which should allow user to record video on iPhone 3GS.
I was looking into MediaPlayer references but could not find anything there. Can someone give me a head start on the APIs to look for?
You want the UIImagePickerController, which is basically a dialog box that you can show to let the user either take pictures or record video.
