Unable to find host target(s) for Extension

Question

Report

What did you do?

I tried to run the pod install command

What did you expect to happen?

Install all pod dependencies correctly like the 1.1.1 version do.

What happened instead?

[!] Unable to find host target(s) for myExtension1, myExtension2. Please add the host targets for the embedded targets to the Podfile. Certain kinds of targets require a host target. A host target is a "parent" target which embeds a "child" target. These are example types of targets that need a host target:
- Framework
- App Extension
- Watch OS 1 Extension
- Messages Extension (except when used with a Messages Application)

Answer 1

The problem is not in the podfile, but in the project!

To fix:

• Go to XCode
• Select your HOST target.
• Open the target's 'General' page

• In the 'Embedded Binaries' section, make sure your EXTENSION target is present.

• In your Podfile you should have:

  target 'HostApp' do .... target 'YourExtension' do .... end end
