AsyncUI

What's AsyncUI?

AsyncUI is a light async UIKit based on <UIKit/UIKit.h>, you can commit UI tasks before main runloop waiting. Also it can limit concurrent thread count by manage limited serial queues.

Combine views into single view.

Podfile

To integrate bench_ios into your Xcode project using CocoaPods, specify it in your Podfile:

platform :ios, '10.0'

target 'TargetName' do
pod 'AsyncUI'
end

Then, run the following command:

$ pod install

Installation:

import "AsyncUI.h"
