Swift_cocoapos import third-party library _ bridge file

• SwiftUse the podimported third-class library to use it easily.
  In Swift5.0here, you can directly use the podimported third-party library without using the bridge file. importYou can use the third-party library directly by directly using the third library class name.
  
  However, such a processing method requires an importoperation that needs to be performed in every place where the third party is needed , which is too troublesome.

• Use bridge files to achieve the same effect as Objective-Cinternal pchfiles

1. Create a file, select Create Header File, and name the file for distinction xxx-Bridging-Header.
2. Modify the configuration and open it Build Setting.
2.1. Search Objective-C Briding Header, and then perform similar operations as shown in Figure

2.2. Search User Header Search Path, and then perform operations as shown in Figure

2.3. Import third-party libraries xxx-Bridging-Heade.h, as shown

in the figure. After performing the above operations, do not perform importoperations where third parties are needed . The effect is as follows:

Note: When podimporting a third party, you also need to pay attention to some operations, Profileadd use_frameworks!this line of code to the file.
