iOS 13 introduces user interface feature. This feature contains two kinds of user interface types, light and dark.

This project is a tool for developers to easily adapt user interface feature in iOS 13.

Use this firm to find podfile script for your project.

Firstly, choose according to the language used in your project (Swift/Objective-C).

Secondly, choose according to whether you are using network image (Local image/Others).

Then, if you are using network image, choose the download method you preferred (SDWebImage/Kingfisher/Custom download method).

• Shortcut method to create UIColor with different user interface type.

• Shortcut method to create UIImage with different user interface type.

• Written in Objective-C. All functions available in Swift with modern APIs.

• Shortcut method to download remoate image with SDWebImage and Kingfisher and create UIImage with different user interface type.

• This code can work on from Xcode 9 to Xcode 11.

• It has an various deployment target version from iOS 8 to iOS 13.

• We found that enable appearence image set in xcassets leads to dramatic lagging in application startup. Some walkaround like combine images into one UIImage object manually is necessory, if you are working with a giant application.
