Errors caused by attributes

Sendbird Voice/Video Calls iOS
1

Hello,

I am getting errors like this:

  • Unknown attribute ‘_inheritsConvenienceInitializers’
  • Unknown attribute ‘_hasMissingDesignatedInitializers’

Used this link to download files: https://github.com/sendbird/UIKit-iOS-Swift

Also, as per the solution tried in X-Code 10 and X-Code 11.3.1 using Swift 4.2. However, the issue is not getting resolved.

Please let me know what needs to be done to solve this.
