Skipped declarations

3 declarations were excluded from these bindings. Each reason comes from the generator or the iOS SDK compiler.

NSManagedObjectContext.fetch(_:)

This declaration needs Swift generic type arguments. (no canonical witness for T)

NSManagedObjectContext.count(for:)

This declaration needs Swift generic type arguments. (no canonical witness for T)

NSManagedObjectContext.perform(schedule:_:)

synchronous callback requires a nonescaping JS-thread call
