}

var xxx: XXX {
    // ...
    // self offset at xxx
    //                ^

// closure
{ [weak self] a, b in
    // self offset at [weak self]
    //                      ^
}

• XXX() Initial

func xxx() {
    abc.xxx()
//  ^
    abc.xxx
//  ^
}

skip type typeusr $sSaySSGD, Swift.Array<Swift.String> typeusr $sSo17OS_dispatch_groupCD, __C.OS_dispatch_group typeusr $sSo6CBUUIDCD, __C.CBUUID 特殊 typealias let cell: DeviceCell = tableView.dequeue(cell: Cell.self, for: indexPath) skip closure

＃ 盲點

1. default skip function 應該沒事？
2. skip nonescaping closure nonescaping closure 會被 skip 實際上應該往上傳遞給 nonescaping closure 的 parent closure 檢查 應該要？
