performance

HTTP

NSURLSession library has NSURLSessionTaskMetrics API for those higher than iOS 10.0. So we can evaluate HTTP network performance by domainLookupTime or secureConnectionTime.

For NSURLConnetion or NSURLSession lower than iOS 10.0, we can only use BSD Socket APIs to collect part of data.

WebView

Either UIWebView or WKWebView implements Performance.timing API above iOS 9. For those lower than iOS 10.0, we also use BSD Socket APIs to collect part of data.

Installation

Drag and use.
