Pods are missing in Targets Xcode iOS

Question

I'm working with MapBox Search API. To avail MapBox libraries -

1. Create a new Project in Xcode

2. Close that project and open that project folder in terminal

3. Run pod init

4. Add these to my Podfile -

   target 'MapBox' do
   use_frameworks!
   pod 'MapboxSearchUI', ">= 1.0.0-beta.3", "< 2.0"
   end
   

5. Run pod Install and got this -

   Analyzing dependencies
   Downloading dependencies
   Using MapboxCommon (9.0.2)
   Using MapboxMobileEvents (0.10.8)
   Using MapboxSearch (1.0.0-beta.4)
   Using MapboxSearchUI (1.0.0-beta.4)
   Generating Pods project
   Integrating client project
   Sending stats
   Pod installation complete! There is 1 dependency from the Podfile and 4 total pods installed.
   

6. But I'm getting error

7. I checked in pods targets and found out that only one pod listed in targets and rests are not -

Targets list in Xcode -

And installed pod list in projects pod directory -

So How can I add the other pods in Xcode Targets?

N.B: I've found this similar question but there are no answares in that and that question is not that elaborative.
