You can read more about it [here](http://stackoverflow.com/questions/30739473/nsurlsession-nsurlconnection-http-load-failed-on-ios-9), [here](https://github.com/Alamofire/Alamofire#app-transport-security) and [here](https://ste.vn/2015/06/10/configuring-app-transport-security-ios-9-osx-10-11/). ![app security](http://i.imgur.com/INEp6q5.png) ## Tips Not all websites will have their info brought, you can treat the info that your implementation gets as you like. But here are two tips about posting a preview: * If some info is missing, you can offer the user to enter it. Take for example the description. * If more than one image is fetched, you can offer the user the feature of picking one image. ## Tests Feel free to fork this repo and add URLs on [SwiftLinkPreviewTests/URLs.swift](SwiftLinkPreviewTests/URLs.swift) to test URLs and help improving this lib. The more URLs the better the reliability. ## Information and Contact Developed by [@LeonardoCardoso](https://github.com/LeonardoCardoso).
