Issue #402 I want to test if a date has passed another date let base = Date(timeIntervalSince1970: 1567756697) XCTAssertEqual(validator.hasPassed(event: event, date: base), true) My hasPassed is using Calendar.current func minuteSinceMidnight(date: Date) -> MinuteSinceMidnight { let calendar = Calendar.current let start = calendar.startOfDay(for: date) return Int(date.timeIntervalSince(start)) / 60 } But the minute is always having timezone applied. Even if I try with DateComponents func minuteSinceMidnight(date: Date) -> MinuteSinceMidnight { let components = calendar....

Issue #377 OneSignal is an alternative for Parse for push notifications but the sdk has many extra stuff and assumptions and lots of swizzling. We can just use Rest to make API calls. From https://github.com/onmyway133/Dust Every official push notification SDK can do many things Register device token. This is crucial for the notification to get from your backend -> APNS -> device Manage player id, user id, arn, …This is used to associate with device token Manager tag, topic, subscription, segments, …This is used to group a set of device tokens Do swizzling, update your application badge number, change your user notification settings, … without your knowing about that Some other fancy stuffs Dust does only one thing, which is push notification handling....
