推荐答案

当我从 Mac App Store 下载 Xcode 时，它​​在启动板中创建了一个名为安装 Xcode"的图标，您可以从那里开始安装.

When I downloaded Xcode from the Mac App Store it created an Icon in launchpad called 'Install Xcode' and you're able to kick off the install from there.

我第一次安装失败，我能够重新安装.

My installation failed the first time and I was able to reinstall fine.
