You haven't closed your tableView:cellForRowAtIndexPath: method properly.

Thank you, such simple mistakes.

Dont forget to indent your code

Saves you from these kind of problems plus makes your code look cleaner and easier to understand

Agreed. An easy way to re-indent your code in Xcode is to select the text, and then simply Control-I (or, via the menus, Editor > Structure > Re-indent).
