Can I use my switch joycons on my iPhone

Hello and welcome to Apple community 🤗

Yes you can but you need ios 16 and your IPhone is not compatible with iOS 16. So you can’t use your joycons Nintendo Switch whit your iPhone 7 Plus. If you have a Oder iPhone compatible with iOS 16 :

• iPhone 8 or later

• iPhone SE 2 or later

Update your iPhone to iOS 16 (look here : Update your iPhone or iPad - Apple Support (CA)) (if you have problems with the update If your iPhone or iPad won't update - Apple Support (CA)) and after go to Settings > Bluetooth > hold the sync button on your two joy con > on the iphone, select both joycon

Note that after connecting them to your iphone it won't do anything because you can't normally (for me anyway) play with them. for me I can just play with the pro controller but not with the joy con. 😕
