我只是想在游乐场中显示一个CollectionView来快速尝试想法。然而,这已经过了一个小时+事情。我收到了错误:

我尝试将视图设置为PlaygroundPage,并创建UIWindow。我不清楚如何使用Playground中的ViewControllers,甚至是否是根本问题以及它是否与let sliceReducers = { first : firstReducer, second : secondReducer }; const initialRootReducer = combineReducers(sliceReducers); const store = createStore(initialRootReducer); // sometime later sliceReducers = { ...sliceReducers, third : thirdReducer } const newRootReducer = combineReducers(sliceReducers); store.replaceReducer(newRootReducer); 异常相关联。

我的游乐场如下:

could not dequeue
