<init>

Platform and version requirements: Native (1.3)

<init>(vararg exceptionClasses: KClass<out Throwable>)

For Common

This annotation indicates what exceptions should be declared by a function when compiled to a platform method in Kotlin/JVM and Kotlin/Native.

For Native

This annotation indicates what exceptions should be declared by a function when compiled to a platform method.

When compiling to Objective-C/Swift framework, non-suspend functions having or inheriting this annotation are represented as NSError*-producing methods in Objective-C and as throws methods in Swift. Representations for suspend functions always have NSError*/Error parameter in completion handler

When Kotlin function called from Swift/Objective-C code throws an exception which is an instance of one of the exceptionClasses or their subclasses, it is propagated as NSError. Other Kotlin exceptions reaching Swift/Objective-C are considered unhandled and cause program termination.

Note: suspend functions without @Throws propagate only kotlin.coroutines.cancellation.CancellationException as NSError. Non-suspend functions without @Throws don't propagate Kotlin exceptions at all.
