A, Swift calls the OC
1. Create {targetName} -Bridging-Header.h header file, BuildSetting -> bridging
The class header file called OC 2. Swift in need {targetName} -Bridging-Header.h importing class
Two, OC calling Swift
1. Xcode generated by default {targetName} -Swift.h in BuildSetting - generated interface>
2. Swift OC classes in the class {targetName} -Swift.h need to import header file, OC Swift access classes is required
- 1. Swift class must extend NSObject
- 2.OC Swift class members access so members must use @objc modified or used directly @objcMembers modified class, indicating that all of the class members are accessible in the OC
