@lildata currently swr can only works very smoothly in browser runtime only (the time when I wrote this reply). the short unofficial work around could be:

useSWR(key, fetcher, {
  isOnline() { /* online detector for ink runtime */ },
  isDocumentVisible() { /* online detector for ink runtime */ },
})

making swr become more flexible for different runtime is still in progress 😃

hmmm I don’t know. My jest tests ran just fine with react-native 0.63.3 and now started to fail with 0.66.3. My swr remained at version 0.4.2. All of the sudden all swr related tests fail.
