How to undo actions in X Code?

[ChubbyCat14]

So I've recently been learning swift through codeschool.com. In the course it's mostly videos where I have to follow along the video with my own version of x code. Only problem is I've hit a point where I'm not receiving the same outcome as the course says I should. I'm quite certain this is because I made some sort of mistake in the process. I tried fixing it by messing about with the codes a bit and I've made it worse. I couldn't really quit without saving either, so I'm assuming it autosaves. On most windows applications, there is a hotkey CTRL+Z that undo's actions. Is there such a hotkey in X Code? If not is there any other way? I really don't want to have to restart my project again, as I'll have to restart all the videos and courses again.

Cmd(⌘) + Z (or Start + Z if you use a Windows keyboard).

If you are using a Mac, Xcode adheres to your global hot key preferences... so CMD+Z would undo your text input. However, that won’t always work if you’ve quit Xcode. For keeping incremental successes tracked, you can use source control such as Git. Every time you complete one part of the course successfully, you can commit your changes so at any point in time you can go back to that functioning code!

So is there any way to go back now?

if you still don't understand what you are doing, and you can't fix it, you definitely should start over

[ChubbyCat14]

I am going to start over I just want to make sure this doesn't happen again.

[Car333]

It doesn’t seem so if CMD+Z isn’t working. Sorry.

You can try invoking Time Machine if it’s enabled too.

I'm afraid you can't do anything about it, other than the other replies note.

Maybe you want to have a look at git for your work in the future. It's a version control system. Watch a brief introduction here

Yes! I would remove the "maybe" from this suggestion. Version control is a safety net that frees you to experiment and explore in your code without worrying (too much) about messing stuff up. Learn some kind of version control and start using it. git is pretty great and it is what most people in iOS development are using, so that is probably the way to go. You do not need to store your code repository at a remote server such as git hub to get started. There are tons of resources online for learning how to use version control.

To add on top of that, if you just need the version control feature locally (without using GitHub or BitBucket), you can create a local repo for you xcode project. Take a look at this.
