Xcode4 just comes to us, developers like me would wonder know more user experiences about it

So post question here to seek pros and cons of xcode4.

Pros

• support git
• one window
• unit test integrated ( how about this feature ? )

Cons

• different GUI & shortcuts against 3.x

What else ?

Other questions:

• any support for UML class diagram etc ?
• how to navigate source codes more easily ?

---

Con's

• Massive download file!
• It's no longer free (still not much to pay, this would be a point if it was upwards of £/$50
• less third party support / tutorials for beginners.
• Something new to learn

Pro's

• Single window - trying to find all the windows can become a nightmare in v3
• New debugger
• auto fixes common errors in code - displays errors straight away
• navigators and jump bar make finding things easier.

Hope this helps

Pros:

• Everything is in one window.
• Auto complete is much better than 3.x version.
• Git support, and the way file versions are displayed.

Cons:

• It looks bit messy on my 13in MBP, I need to buy bigger display.
• Shortcut-key are not same for common operations what they used be in 3.x version

I using it only for 2 days and i like the function that it shows fails immeditely i do not have to run the code.The biggest con is i think that they try to give everything to same place so when you use the build in IB it is a bit mess.I liked the separate version.

so like i said I using it only for 2 days so...

hope it helps
