Hi Yun Yin Ku,

I think the challenge asked for a starting array with 6 elements. That might be tripping it up. Also, when you concatenate an element, you need to assign it back to the array. Try arrayOfInts += [7] For the removal of an element, the challenge asks you to assign it to a constant called 'discardedValue' so start with let discardedValue = then use the .remove method on the array. hope this helps...
