Hello,

I have a class in Kotlin with methods such as

class MyClass {
    private val arrayQueue = ArrayQueue<String>()

    fun save(item: String) {
        arrayQueue.add(item);
    }

    val last: String
        get() = arrayQueue.last()
}

I use it in objective C

+ (instancetype)sharedInstance {
    static NativeClass *nativeClass = nil;
    static dispatch_once_t onceToken;

    dispatch_once(&onceToken, ^{
        nativeClass = [[NativeClass alloc] init];
        nativeClass.myClass = [[MyClass alloc] init];
    });

    return nativeClass;
}

First of all, accessing it was an issue just to get .last, so I created a wrapper to get a frozen version.

fun getMyClass() = MyClass().freeze()

But by doing this, I cannot mutate it anymore kotlin.native.concurrent.InvalidMutabilityException: mutation attempt of frozen

How can I overcome this kind of issue?

Hmm, the class needs to be frozen, but I can use mutable field with IsolateState
