Possible issues and solutions Android Studio In your first project, you will use a different iOS framework distribution option. You may ignore KDoctor's warnings regarding the CocoaPods installation.

Last edit (for now): you should also look at using lazy as described in the other answers. On a final note, you can check out Kotlin Android Extensions, which eliminates the need to create properties for your Views altogether, if it works for your project.
This will make a regular call if btnProceed is a non-null value, and do nothing otherwise. Instead of the unsafe !! operator though, which the converter often uses, you should use the safe call operator where you access the property: btnProceed?.setOnClickListener Otherwise, if you want the compiler to guarantee safe access for you, you can make the Button nullable as the converter does by default. If the property is read before a real value is assigned to it, it will throw an exception at runtime – by using lateinit, you’re taking the responsibility for initializing it before you access it for the first time. It’s there precisely for classes like Activities, when initialization happens in a separate initializer method, later than the constructor being run (in this case, onCreate).
Marking a property lateinit allows you to make it non nullable, but not assign it a value at the time that your Activity’s constructor is called.
