unityのエラーがどうしてもわからない

Question

unityでARKitを使いiPhoneへARアプリを作ろうとしているのですが、ビルドをしようとしたらいくつかエラーが出てしまいました。ネットでエラーを調べてもよくわかりませんでした。
unityのことはからっきしなのでどなたか分かる方がいらしたら教えていただきたいです。

}

Answer 1

Update()の中でIsPointerOverUIObject()が定義されています。

蛇足ですが、#if ～ #else ～ #endifで条件に当てはまらない箇所はコンパイル時に無視されます（すなわち、書いていないのと同じように扱われます）。
エディタでの編集中にはエラーは出ないが、iOSへのビルド時にエラーが出たのはそのためです。
エラー内容自体は、普通にエラー文を読んで該当の行を見ればわかる内容なので、この点に注意しましょう。

無事ビルドできました！
unityだけでなくc#も勉強しなくてはですね...
解答していただきありがとうございました！
