The Nintendo Switch Online app will be updated this summer, and it will need iPhones running iOS 14 or later.
We are now on iOS 15, and iOS 16 is expected to be released in September. However, if you have an older iPhone, the app will not work, which may be an issue for some. The iPhone 6S was the first smartphone to run iOS 14, so if you have that or a newer iPhone, you should be OK utilizing the Nintendo Switch Online app.
2022年夏ごろに、iOS版『Nintendo Switch Online』アプリのアップデートを実施予定です。このアップデートで動作環境を「iOSバージョン14.0以降」に変更します。
「iOSバージョン13以前」の端末ではアプリがご利用いただけなくなりますので、ご注意ください。 https://t.co/8MAqv91nHe
