Installation

By default it will install into /Xcode4, so you are safe to just click though almost blindly. This could change after the final release.

After install size is 5GB.

Launch

Very unstable, crashed on the first launch, the reason was because of all my existing Xcode 3 plugins.

Crashed again after removing all the plugins. Then succeed on relaunch.

Look and feel

As you’ve already see from the internet, the first reaction is this thing looks more like iTunes than Xcode 3.

Organizer

Organizer has been redesigned from ground up, it’s much easy to find the information you want.

Another very interesting thing for Organizer is Document has been merged into Organizer now, which will help me to have one less window open.

Preferences

Preferences window has been redesigned and simplified, there are only 7 icons you can click on:

Alerts, which is new. Documents, Fonts & Colors, Text Editing, Key Binding, Building and Source Trees.

Workspace

Favorites Bar is gone, replaced with much more useful Tab bar!

“Get Info” has been converted into “Utility” and put into the workspace as right sidebar.

Original “Project” Tree has been converted into tab based navigator as left sidebar.

Alerts

If you’ve already tried “GrowlCode“, this is not new for you. If not, you’ll love this feature.

iPhone Simulator

There’s one new default app in iPhone Simulator: Game Center, can’t get it working though.

All-in-all

Very well redesigned! Very buggy!
