WKWebKitを使用した際のThread 1: signal SIGABRTエラーの解決方法
取得したURLのページをWKWebKitを使用して表示しようとした際に問題が発生。
なぜかThread 1: signal SIGABRTエラーが発生してしまった。
以下がエラー内容。
Terminating app due to uncaught exception 'NSInvalidUnarchiveOperationException', reason: 'Could not instantiate class named WKWebView because no class named WKWebView was found; the class needs to be defined in source code or linked in from a library (ensure the class is part of the correct target)'

WKWebKitを使用する際には、Build PhasesのLink Binary With LibrariesでWebKit.frameworkをリンクする必要があるのだが、その設定ができていなかった。
ちなみに、エラー個所を探そうと思ってブレークを貼るとなぜかエラーが発生しなかった・・・。
なぜエラーが発生したのかはいまいち分からない・・・。
結構難しい話が絡んできそうなので説明できるようになった際に追記を行おうと思う。
