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....

Issue #373 UIButton.contentEdgeInsets does not play well with Auto Layout, we need to use intrinsicContentSize final class InsetButton: UIButton { required init(text: String) { super.init(frame: .zero) titleLabel?.textColor = .white setTitle(text, for: .normal) layer.cornerRadius = 15 layer.masksToBounds = true backgroundColor = .black isUserInteractionEnabled = false } required init?(coder aDecoder: NSCoder) { fatalError() } override var intrinsicContentSize: CGSize { let size = super.intrinsicContentSize return CGSize(width: size.width + 24, height: size.height) } }

Issue #346 We have FrontCard that contains number and expiration date, BackCard that contains CVC. CardView is used to contain front and back sides for flipping transition. We leverage STPPaymentCardTextField from Stripe for working input fields, then CardHandler is used to parse STPPaymentCardTextField content and update our UI. For masked credit card numbers, we pad string to fit 16 characters with ● symbol, then chunk into 4 parts and zip with labels to update....

Issue #345 UIButton with system type has implicit animation for setTitle(_:for:) Use this method to set the title for the button. The title you specify derives its formatting from the button’s associated label object. If you set both a title and an attributed title for the button, the button prefers the use of the attributed title over this one. At a minimum, you should set the value for the normal state....

Issue #344 addSubview can trigger viewDidLayoutSubviews, so be careful to just do layout stuff in viewDidLayoutSubviews This method establishes a strong reference to view and sets its next responder to the receiver, which is its new superview. Views can have only one superview. If view already has a superview and that view is not the receiver, this method removes the previous superview before making the receiver its new superview....
