From <a href="https://devforums.apple.com/message/84647#84647" rel="noreferrer">this thread on ADC</a>:

get-task-allow, when signed into an application, allows other processes (like the debugger) to attach to your app. Distribution profiles require that this value be turned off, while development profiles require this value to be turned on (otherwise Xcode would never be able to launch and attach to your app).

For xcode 4:you have to create Entitlements.plist file from new file. and
Targets->build Settings->Code Signing Entitlements you have to write here "Entitlements.plist"

I did this and xcode don not get anymore error

blocks|key|1528856|text|虽然你的answer是正确的，但我只想更具体地说明这一点，这样想知道get_task_allow到底是什么意思的人就可以了。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1528857|get_task_allow是一种授权，允许其他应用程序获取您应用程序的任务端口。这意味着，如果任何其他应用程序使用您的应用程序进程ID运行task_for_pid()，它们将获得您的应用程序的任务端口，这样它们就可以做一些事情，例如在内存中写入和读取内容，从而能够对您的应用程序的行为进行修补和修改。|1528858|如果你看一下越狱是如何工作的，你会注意到他们做的第一件事就是获取task_for_pid(mach_task_self(),0,&kernel_task);，因为kernel_task是一个值为0的mach_port_t，所以他们能够接触到内核的内存。|1528859|由于内核授权没有get_task_allow授权，苹果甚至排除了使用tfp0(task_for_pid+0)的可能性，因此他们需要一个补丁。|1528860|因此，基本上由于Xcode需要接触你的应用程序的内存并使用它来调试它，所以你需要在调试时启用它，但你需要禁用它来分发你的应用程序，否则任何应用程序都可以获得你的任务端口。|1528861|entityMap|0|LINK|mutability|MUTABLE|url|https://stackoverflow.com/a/1026472/9647800^0|Y|E|4|6|0|0|0|E|1Y|E|0|W|1A|29|B|2P|1|2R|B|0|8|E|Y|4|13|E|0|0^^$0|@$1|2|3|4|5|6|7|V|8|@$9|W|A|X|B|C]]|D|@$9|Y|A|Z|1|10]]|E|$]]|$1|F|3|G|5|6|7|11|8|@$9|12|A|13|B|C]|$9|14|A|15|B|C]]|D|@]|E|$]]|$1|H|3|I|5|6|7|16|8|@$9|17|A|18|B|C]|$9|19|A|1A|B|C]|$9|1B|A|1C|B|C]|$9|1D|A|1E|B|C]]|D|@]|E|$]]|$1|J|3|K|5|6|7|1F|8|@$9|1G|A|1H|B|C]|$9|1I|A|1J|B|C]|$9|1K|A|1L|B|C]]|D|@]|E|$]]|$1|L|3|M|5|6|7|1M|8|@]|D|@]|E|$]]|$1|N|3|-4|5|6|7|1N|8|@]|D|@]|E|$]]]|O|$P|$5|Q|R|S|E|$T|U]]]]

While your <a href="https://stackoverflow.com/a/1026472/9647800">answer</a> is correct, I just want to be more specific on this just so people who want to know what does exactly <code>get_task_allow</code> mean, can.

<code>get_task_allow</code> is an entitlement that allows other apps to get the task port of your app. This means that if any other app runs <code>task_for_pid()</code> with your app process ID they'll get the task port of your app so they can do things like for example writing and reading things on the memory, therefore being able to patch things and modify the behavior of your app.

If you take a look at how a jailbreak works, you'll notice one of the first things they do is get <code>task_for_pid(mach_task_self(),0,&amp;kernel_task);</code> being that <code>kernel_task</code> is a <code>mach_port_t</code> with value <code>0</code>, so they are able to touch the kernel's memory.

As kernel entitlements do not have <code>get_task_allow</code> entitlement, and Apple has even removed the possibility of doing <code>tfp0</code>(<code>task_for_pid 0</code>), they need a patch.

So basically as Xcode needs to touch your app's memory and work with it to debug it, you'll need to enable this for debugging, but you'll need to disable this to distribute your app or else any app would be able to get your task port.

When I set up my entitlements in my iPhone app project, I create a new Entitlements.plist, and set the value of get-task-allow to false. But why? What does this key represent?
Note this is related to <a href="https://stackoverflow.com/questions/997884/application-could-not-be-verified-error-when-building-app-for-iphone-device">Application could not be verified error when building app for iPhone device</a> - I found that flipping the value of this key to true allowed me to install the app on my device)

What does get-task-allow do in Xcode?

调试器

Xcode

当我在iPhone应用程序项目中设置权限时，我创建了一个新任务，并将get- Entitlements.plist -allow的值设置为false。但是为什么呢？这个键代表什么？请注意，这与相关-我发现将此键的值反转为true允许我在设备上安装应用程序)
