Need to add `Import UIKit` inside QiscusCore.swift

[khairunsh]

I tried to remove it from CocoaPods and added the latest version of QiscusCore at 1.13.4 with Swift Package Manager.

XCode 15.0.1
MacOS 14.0

you can use branch master for using Swift Package Manager, i will release stable version in next release

Thanks
