Framework not found pods

Question

I know this is an old issue. But i produced this issue in a very strange way. Actually I had developed an app installed pods and everything in Deployment Target as 11.2. I took a an .ipa for it and sent it to the client for testing. But the Client is unable to install because the iPad Mini 1 is not having an iOS 10 or above update. So I reduced the deployment target to 9.3 current iOS version of iPad Mini1 that the client is having. On taking an archive Xcode produces the error like this:

what is the issue?? Do we need to Unintall pods and install again or just modify the existing pod file? Please Help.

Answer 1

Make sure your Podfile also specifies iOS 9.3 as the deployment target:

platform :ios, '9.3'

Answer 2

I tried fixing my Podfile, but this didn't work for me.

I did the below to fix this issue :

Go to Project Navigator -> Targets -> OneSignalNotificationServiceExtension Target

under Frameworks and Libraries I found this :

I removed Pods_OneSignalNotificationServiceExtension.framework

and build my project and it worked perfect.

Thank you
