First create a single view project for SwiftThen create the OC file directly in the project:Then select the OC language and ask if you want to automatically create intermediate files for OC and Swift:Then there are three files in the project folder:Now an example is written in the OC header file and the implementation file:Then in the swift language and the Obje...ridging-header.h fileYou can then use it directly in the Swift language:Swift language and Objective-c language

Method-" Call C # Internal object Method-"return resultC#/js method to invoke an object-"Find JS Method-" return result2. Interface, because the interface must create an interface to implement the object, then we can not dynamically create the class platform, we have no way, so we have to create a common interface, temporarily called JS Universal interface, (can be generated by the code generator by default) inside is an empty implementation, there is a portal to JS, The process is probably lik

The recent swift fire also wants to try to use it, considering that Swift comes out for a short time, and whether it is too mundane for Apple to update or not to develop existing projects with Swift.Let's take a look at the problems I've encountered:Question One,The cause of the problem is that the build target file cannot generate more than one at compile time. It doesn't seem to understand what it means. Decisive Baidu!The ultimate solution: http://stackoverflow.com/questions/24812983/ Xcode-a

1. K-means algorithmThe loss function of the K-means algorithm can be written asWhere, for the indicator variable, the data n is assigned to the class K, the mean value of the class K. The core of the K-means algorithm is to find and to minimize the loss function. The optimization method is alternating optimization, which is based on optimization J, and remains unchanged. Also based on optimization J, unchanged. These two stages are called the EM algorithm's E (expectation) step and M (maximizat
