App stürzt immer wieder ab und erstellt ein PygLatin-Spiel - Objective C

Question

Ich bin neu in der Programmierung von Objektiven C.

Ich habe eine PygLatin-Anwendung erstellt, aber es stürzt immer wieder ab. Sag mir, wenn du Probleme mit meinem Code entdeckt hast.

App beenden aufgrund nicht abgefangene Ausnahme 'NSRangeException', Grund: ' - [__ NSArrayM objectAtIndex:]: Index 5 über Grenzen [0 .. 4]' ersten Wurf Call-Stack:

würde mich freuen, alle Hilfe, die ich bekommen kann, danke! :)

setzen
self.subsequentCharCount++;
am Ende der while-Schleife bedeutet unter
[self print: completedWord];
