kotlin

问题 I tried to check, lateinit variable is initialized or not in a function using reference operator. The function name and variable name is same in this case. So that Kotlin throws Overload resolution ambiguity. All these functions match exception. Actually what's wrong in this code? class ABC class MyClass { private lateinit var abc: ABC fun abc() { if(!::abc.isInitialized){ println("Hello") } } } 回答1: It's a simple name clash. The compiler does not know whether you're referring to the method

问题 I'm working on a Kotlin-multiplatform (KMP) library for iOS / Android. I have written some unit tests for JVM, for which I use MockK to create spies and mocks, but MockK doesn't support Kotlin native fully yet. Therefore, I was wondering how others working on KMP projects write unit tests for the iOS platform. An example would be really appreciated. 回答1: Currently, MockK does not support Kotlin/Native or Kotlin/JS. However, both are placed as important items on the project backlog: Kotlin
