![]() Take note - the astute developer may have noticed that this variable will actually be an optional Int since its assignment involved the try? keyword. This technique is especially useful for scenarios where one wants to handle errors in a similar fashion. If that isn’t the case, it’s assigned the return value. If hoursOfHaloPlayedThisWeekend()` does throw an exception, haloPlayTime will be nil. It’s also a natural fit to use guard in such scenarios:įunc hoursOfHaloPlayedThisWeekend () -> Int throws let haloPlayTime : Int = try ? hoursOfHaloPlayedThisWeekend () For these murky waters, it’s important to identify these regions as such to indicate that program flow can and will change.įor functions that could produce an exception, it’s wise to mark them as such with the throws keyword. Should you be interested in going with anything other than option 5, please read on: Act IV: Handling ErrorsĪs the developer of your app, you are keen about parts of it that could raise an exception. You go back to looking at the top 25 downloads in the App Store with longing eyes, letting your dream of occupying the space slowly die inside your cold, bitter heart. Asserting that an error won’t occur (playing with fire).It’s treated as an optional value (still alright).Once an error finds itself executing, a few things could happen: To demonstrate, allow me to provide you a mechanism to determine if your weekend is going be NSAwesome or NSStressful: This design encourages developers to really analyze problems and evaluate how things could go south - and then provide context as to why. Swift enforces meaningful errors by representing them as values of types. If you fall among the former rather than the latter, you’ll want to know about the ErrorType protocol. Act II: ErrorType ProtocolĪt this point in your Swift endeavors, you are either learning to embrace Swift’s new way of thinking or staying steadfast in your battle tested ways. Perhaps unsurprisingly, all ideas work together to form one cohesive unit with which to handle errors. Among them are constructs for throwing, catching, manipulating recoverable errors at runtime, and propagating exceptions.Īdding more power to the mix is the fact that Swift’s error handling interops nicely with our old friend NSError. Swift 2 was gracious enough to provide a robust set of tools with which to handle one’s errors in code. Be that as it may, we like to think things won’t explode spectacularly in our software. Unless you are LLVM, Skynet, or this guy - it’s certain that you will not bat 1.000. It’s a humble thing, really, programming for your inevitable failure. And Swift 2 issues developers a syntactically pleasing way to stay safe in the event of disaster. Knowing things could go south but continuing along with confidence. On the other? A bright light promising that things will be okay, even if the worst comes to pass. On one side stands the notion of providing a fail safe when things so wrong. 1.Both ideas are not glamorous, but in tandem they provide stability in the world of programming. To resolve it, Atlantis offers certain functions to help you manually* add your Request and Response that will present on the Proxyman app as usual. However, if your app doesn't use any one of them, Atlantis is not able to automatically capture the network traffic. Back to Proxyman app and inspect your HTTPS Request/Response.īy default, if your iOS app uses Apple's Networking classes (e.g URLSession) or using popular Networking libraries (e.g Alamofire and AFNetworking) to make an HTTP Request, Atlantis will work OUT OF THE BOX.Start the project with any iPhone/iPad Simulator.Open iOS Project at Example/Atlantis-Example-App.xcodeproj.Run Example AppĪtlantis provides a simple example that it can demonstrate how to integrate and use Atlantis and Proxyman. You don't need to config anything, it works out of the box. Create a Carthage Script as the Carthage guidelineįor Carthage with Xcode 12, please check out the workaround: WS/WSS Trafficįrom Atlantis 1.9.0+, Atlantis is capable of capturing all WS/WSS Traffic, which is made by URLSessionWebSocketTask, and send to Proxyman app.
