Whenever I open my project and go to this file, or open it separately, XCode freezes.

Please help. I would remove the particular characters that are causing this problem, but I don't know which ones they are.

It was working just fine the first time I pasted it in and compiled, but after I closed and re-opened the project it froze when I tried to open the source file.
