Can Unity codes be converted to both iOS and Android codes?

Hi, guys! Before you start reading, I thank you in advance for reading my question!

Basically, I'm new to Unity but I have solid knowledge in programming (I've been programming for 3 years).
The reason I want to use Unity is that I'm planning to make simple mobiles on both Android and iOS.
From what I read so far, if I code on Unity using C#, I can convert the programme to different platforms including Android and iOS.
However, if I were to not use Unity, I'd have to use Java for Android and Swift or Objective-C for iOS.

So my question, can my game built with Unity (programmed with only C#) be transformed into both Android and iOS games without having to code in Java and Swift or Objective-C?
If so, how is that possible?? Does Unity automatically converts my C# code to Java Swift or Objective-C?


Thank you so much for reading and I'd really appreciate any comments!

 

Yes, this is what Unity is great at. Create your app in the editor, and then build to your targets, i.e. iOS and Android in your case.

 

So, when I convert the code, can it be directly uploaded to Appstore and Play Store?

 

Well, it's not as simple as that.

I don't have experience of Android, but I can tell you about iOS.

When you build from Unity an Xcode project is created, which you can build and then run on a device. In Xcode you can also create the package which will be submitted to Apple (for the AppStore). There are other things you need to do in the Apple Developer site and iTunes Connect in order to actually get the app released on the AppStore.

 

That sounds great! Do you think the converted code by Unity is slower than the ones made by Swift/Objective-C or wouldn't there be much difference? I really appreciate answering my questions!!

 

Yes. Unity is a build once, deploy everywhere system. You can make a single game, then deploy it to the web, PC, MAC, Andoid, iPhone, XBox, PlayStation... and so on. There is even a legendary 'deploy to toaster' button lurking somewhere in the depths of the editor.

 

Don't know. I wouldn't worry about it.

 

^kinda reminds of that java model thingy. Shame things have gone back to using native languages wherever poss. Just means my battery life on my phone lasts longer and doesn't need a bloated framework/virtual machine to run a bit of software. *sigh*

 

If you have assets with native code they need to have build targets for your target platform. I know some are missing UWP for example.

 

Just a heads up. A Mac will be required for the IOS deployment, even if you use the cloud build, you still need application loader to upload to the app store.
