結論

16G(以上)のUSBメモリ用意して中古のiMACに最新のmacOSとXCodeを入れる

USBメモリ ➡ 32Gがamazonで500円くらいで買える
iMAC ➡ 2014年くらいのだとリコレで30000円くらいで買える

背景

iOSで手軽に色々やりたい
UIに時間かけたくない
お金もかけたくない

経緯

Sonoma

Reactの環境を新しくしようと
この辺とか見て
やってみたがなんかXcodeが古いとか言われて動かない

mac買い替えだと、、、
ノートPCに60万超えってなんやねん

Windowsだって結局古いPCにインストール出来るようになったんだし
Linuxは当然古いPCで動く
macだけ動かないとか無いやろ
と思って調べて見ると、OCLPとかいうのがあるらしい

手順はこのサイトの通りにやった

で、SonomaにしてXcodeも最新の15.1がApp Storeからインストールできた。

一応法的にもセーフらしい

とりあえず単体で動いた

React Native

気を取り直してRNのインストールと実行

なんかビルドに失敗してる
