I have a web/ios react-native project. On web this works without any issue, but on iOS I am getting an error. Strangely, I dont see the error at all in the debug window, so I have to rely on the red screen.
The way I am saving the data is like this:
console.log(`user progress: writing string of >>${JSON.stringify(user.progress)}<< original's type: '${typeof user.progress}'`)
await AsyncStorage.setItem(
appConfig.constants.graphcool.progress,
user.progress
)
And that log is the last log I see in the debugger:
user progress: writing string of >>{"VocabularyPairs":{"1":0.984375,"2":0.996875,"3":0.875}}<< original's type: 'object'
I am getting a red screen with error in iOS:
Exception '-[NSDictionaryM length]: unrecognized selector sent to instance 0x2832c5ce0' was thrown while invoking multiSet on target AsyncLocalStorage with params (
(
(
progress,
{
VocabularyPairs = {
1 = "0.984375";
2 = "0.996875";
3 = "0.875";
};
}
)
),
311
)
So -- I can fix this by changing the code:
await AsyncStorage.setItem(
appConfig.constants.graphcool.progress,
Platform.OS === 'ios' ? JSON.stringify(user.progress): user.progress
)
But my question is, why do I have to? If I do fix it, there are two other places that also set this same item -- one already has that wrapper, the other does not. Both work, and it is always almost the same data -- the numbers (that is, the values) may change, but they are string-keys and number values everywhere.
What makes the first write special?
