Match App - Delegates Protocol - Crashing

No errors in my code but app crashes when run and returns this error.
can’t figure it out…
I have just gone through the Protocols and Delegates Lesson.

Your outlets are not connected by the looks of it.

odd that. They looked fine and no errors in the code line. I removed and re-connected them and now all works fine. I wonder what can cause the link to fail? Fairly sure I connected them correctly earlier in the coding

your outlets are not connected properly, this can be seen easily by looking at the line numbers (13 and 16) they are not shaded, if its connected properly it should be shaded. check your connections and it should resolve your problem
