📌 What Changed In The Repo

Biggest evolution was shipping AquaVibe from zero to production app during RevenueCat Ship-a-ton, and implementing reliable State of Mind fetching/saving with HealthKit for iOS 18+.

🏆 Standout Success

AquaVibe was created from scratch to a fully working iOS application during RevenueCat Ship-a-ton competition.

AquaVibe won a Participation Prize in RevenueCat Ship-a-ton competition.

The most challenging part was understanding State of Mind logic. Documentation and sample projects were not enough, so extensive testing was needed to verify how to correctly fetch and save mood/emotion data to Apple HealthKit.

State of Mind is also new from iOS 18, so high-quality implementation references were limited.

func fetchStateOfMindData(forKind kind: HKStateOfMind.Kind) async throws -> [HKStateOfMind] {
        do {
            let stateOfMindType = HKSampleType.stateOfMindType()
            
            // Create a predicate for the specified kind
            let kindPredicate = HKQuery.predicateForStatesOfMind(with: kind)
            
            // Combine with the sample type predicate
            let combinedPredicate = NSCompoundPredicate(andPredicateWithSubpredicates: [
                HKQuery.predicateForSamples(withStart: nil, end: nil, options: .strictStartDate),
                kindPredicate
            ])
            
            let descriptor = HKSampleQueryDescriptor(
                predicates: [.sample(type: stateOfMindType, predicate: combinedPredicate)],
                sortDescriptors: [SortDescriptor(\.startDate, order: .reverse)]
            )
            
            let samples = try await descriptor.result(for: store)
            
            if let stateOfMindSamples = samples as? [HKStateOfMind] {
                print("✅ Fetch done for \(kind)")
                print("Number of samples: \(stateOfMindSamples.count)")
                return stateOfMindSamples
            } else {
                print("❌ No HKStateOfMind samples found for \(kind)")
                return []
            }
        } catch {
            print("❌ Error fetching state of mind data for \(kind): \(error.localizedDescription)")
            return []
        }
    }

✅ Entireness

Nevertheless, while creating this mood and water intake reminder app, I have also included:

Concurrency
Error handling & alerts
Text input validation
Project organization - MVVM Architecture
