App Sandbox capability missing in Xcode project

Question

According to this guide, there should be an App Sandbox capability in the project file:

However, for some reason my app project does not have any App Sandbox capability that I can turn on:

Why is it missing, and how can I get it there?

Answer 1

First of all, you should open the ***.entitlements file. In this file, add a Key named App Sandbox and changed Value to YES.

After completing the above steps, click command + b then go back to Signing & Capabilities, the App Sandbox will appear.

Answer 2

If your Apple provisioning profile is missing the App Sandbox entitlement then it won't show up in xcode.

FYI - you can add manually to entitlement file, however it wont let you build unless described in your provisioning profile. Same goes for ditribution as well.

To Add entitlement > Open *.entitlements file as source code > add the following code.

<key>App Sandbox</key> <true/>

You can regenerate the provisioning profile with the desired capabilities, if you are the admin/team agent of the Apple store project.

hope this helps.
