As follows, what expression should I write to access let learningList? In the code, query is a class, find is a function. Many thanks!
_ = query.find { result in
switch result {
case .success(objects: let learningList):
break
case .failure(error: let error):
print(error)
}
}
That is a local variable, so you can access it only in the decelerated context, i.e. inside case. If you need to use it later you have to create a property in caller class to hold it, like
_ = query.find { [weak self] result in // << ref to caller
switch result {
case .success(objects: let learningList):
self?.learningList = learningList // << safe in caller's property
break
case .failure(error: let error):
print(error)
}
}
