How to use machine language in iOS can anyone help me out.
Is it possible in objective c and swift both or not.

Swift (though not natively): see this SO.

So I started a react native app using create-react-native-app and it created a lot of boilerplate code. Android is in JAVA which I am fine with. But the iOS is in Objective-C and I am more familiar with Swift. Is there anything I can do about that? I know most of my code is going to be in JavaScript anyways, but just wondering anyways.
Unfortunately, there is not a simple or one command way to convert your iOS code in your React Native project from Objective-C to Swift. However if you want to write a Native Module, which you'll need to eject from CRN or start a new project with react-native init, you can write new code in Swift.
You might also be interested in this post on how to bridge Swift and Objective-C code. Basically when you create a new swift file you need to make sure to select “Create Bridging Header” when prompted.
You're problem is not that clear. But lemme say this if you wanted to work on cross platform then react native is a good choice to that if you wanted to use javscript. Regarding on your question which is , lemme quote "But the IOS is in Objective C" which is you're wrong you can write an iOS native using both objective c , even c and c++ , ..and swift which you say your familiar with and if you're avoiding objective c then you can write iOS app purely in swift. Hope that helps.
Tips
1 for cross platform - and you want js (react native)
2. cross platform and you wanted to use c# (Xamarine)
3. iOS app which is native (Swift or objective c) or both
4. hybrid , you can try framework like ionic, cordova etc.
5. let us include android , you can use java(kotlin
You can convert swift to objective c or objective c to swift.
There are bunch of options for that, If you want to use javascript for converting than use obj2swift.js: https://github.com/okaxaki/objc2swift.
If you want to convert your code online than you can use online language converter like swiftify:

I have converted a project from the attached link to Swift UIHierarchyView for Objective C – iOS platform
As I don't have a very good knowledge in Swift, I am looking for some help who can review this code and guide me further to make this project stable.
My existing iOS app is in objective c language and i want to add more functionality in my app and i want to do that code in swift language.
So is it possible to create an app which contains both the languages(i.e. in objective c & swift) and Is my app will work fine?
In short answer, Yes.
If you have existing project written in objective-c then you can add new classes written in swift. You still have choice if you want to use swift 3.0 ot swift 2.0.
You have to use bridge class in order to achieve that. You will get more guide on Link provided on Apple website.

However going forward it would make sense that you spend more time on Learning Swift as Apple is now leaning towards Swift 3.0.
Here is link quick guide.
I have just started working in iOS8. I have seen here Playground concept. But I didn't understand it. I have read that it could be only used with the Swift language.
I have referred documents from this link .
Can we use it with Objective-C too?
Thanks for any help!!
The playground concept is built upon a technology called REPL (More info on REPL)
Basically you can type code into the playground which is 'compiled' (evaluated) on the fly so you can see the output/result.
It's quite a nice way to play with a language, design a function or test an algorithm, but you cannot build a distributable app with a playground.
For a playground concept to work a given language needs to support REPL. Currently Objective C does not support this, therefore only Swift is available in playground form.
I believe, Swift is a compile time language.
But Im not sure whether it works on top of Objective C or it's a stand alone language.
Can someone please explain this?

It's a separate language, with its own compiler. It interoperates with Objective-C and can use all of the existing Objective-C libraries.
