如何在iOS中将常规应用添加到现有扩展中？

Question

I created an iMessage app extension with the predefined Xcode template. I now want to add a 'normal' app to that extension. How should I proceed? I just tried to add a storyboard and a new scheme but it fails with following error:

The request was denied by service delegate (SBMainWorkspace) for reason: NotFound ("Application "mybundleid" is unknown to FrontBoard").

Answer 1

Add a new target of type Single View Application to your project:

Then select all source files (.swift, .storyboard) you want to use within your new app and tick the new target in "Target Membership":

Update:

After further discussion in the comments, I understand you want to:

• The user installs an iMessage extension from the iMessage extention App Store within iMessages
• A depending app is installed (and shown to the user on home screen) automatically in the same installation process.

This is not possible. The App shown in the project is actually installed but is hidden/not visible to the user.

The only way to install App and extension at the same time is to install an actual app.
