The simulator installs apps into:

<pre><code>"$HOME/Library/Application Support/iPhone Simulator/User/Applications"
</code></pre>

Also check:

<pre><code>"$HOME/Library/Developer/CoreSimulator/Devices"
</code></pre>

The GUID files and directories match up to the simulator's installed apps.

Manually delete all those files/directories to remove all applications from the simulator.

I know there is some way to add scripts to the build process in XCode.

Also it looks as if XCode changes the GUID it uses each build (the directory where my app sits changes between builds in XCode), so trying to delete the same directory all the time won't work. If you are only working on one app at a time then clearing out the entire directory would be an option.

blocks|key|1379557|text|我这样做的方法是，只需在模拟器中单击并按住我的应用程序的图标--然后当它开始摆动时，单击黑白(x)。将弹出一条消息，询问您是否真的要删除，您只需单击yes即可。下一次你构建和部署你的应用程序时，它将使用新的sqlite+db，并且你不需要在文件系统中胡乱操作。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1379558|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

The way I do this is to simply click and hold on the icon for my app in the simulator--then when it starts to wiggle click the black and white (x). A message will pop up asking whether you really want to delete and you just click yes. The next time you build and deploy your app it will use the new sqlite db without a hitch and you don't have to go muck around in the filesystem.

What you are really trying to do is to clear out your database, if you've changed the schema. One way to do this, and it would make you happier in the long run when you start shipping version 2.0, 3.0, etc. of your app, is to check the version of your sqlite table, and if it has changed, then discard the old file and use the one in your bundle. 

Finding a way to clean up the Simulator won't help the real world problem of how to clean up a customer's iPhone when you ship a new version with a new schema.

For extra points, after determining that you have encountered an old schema, you may want to copy the new database over without destroying the old one, and load any interesting data out of the old database, into the new one. Then blow away the old database. That way you can preserve your user's additions to the database.

Is there a straightforward way to clean up the directory where xcode deploys an app when building for the iPhone simulator? I have a sqlite database that gets copied into the Documents folder on startup if necessary. The problem is that I might change my schema, but the new database won't get copied, because one already exists.

Ideally, every time I build, it would nuke the previous contents. Is this possible, or do I have to manually do it?

Cleaning up the iPhone simulator

在为iPhone模拟器构建应用程序时，有没有一种简单的方法可以清理xcode部署应用程序的目录？我有一个sqlite数据库，如果需要，它会在启动时复制到Documents文件夹中。问题是我可能会更改我的模式，但是新的数据库不会被复制，因为其中一个已经存在。理想情况下，每次我构建的时候，它都会破坏之前的内容。这是可能的吗，还是我必须手动完成？
