Big thanks to Webkul and his team for helping get Opencart 184.108.40.206 release ready!
Sometimes we require to call methods from one viewController1 to another viewcontroller2 and also get data from viewcontroller2 to viewcontroller1
for this, we need to make the link between two viewcontroller so that can communicate when another viewcontroller completes their work.
here I will show two class where the first class name “Home.swift” and all delegate method declare in “Global.swift” class .
1: first we need to define “Global.swift” class its Parent is NSObject
2: here I have defined two delegate method (write as the comment) . this method we have to define in Home.swift
3: Now I will show Home.swift class . To call , To receive message
4: Now you can use this technique in any classes .
