定义了这么个数组字面量,没问题.
let a = [[["a","b","c","d"],[1,1,1,1]]]
我写成
let a = [[["a","b","c","d"],[1,1,1,1]],[["u","i","o","p"],[2,2,2,2]]]
报错
'[Array<Array<NSObject>>]' is not convertible to 'IntegerLiteralConvertible'
playground里没问题 ，写程序里就报错,而且会导致xcode出问题,代码高亮乱了,顶部一直在indexing,把这个数组再写大些,xcode就爆掉了,显示占用内存10G - -
