In the address field in Safari, type the URL of your web app and press the Return key. From the Home screen, click Safari. Use Safari to test your iOS web apps directly on your Mac.
You configure your simulator or iOS device to pass all networking requests and responses through Charles Proxy, so you’ll be able to inspect and even change data midstream to test how your app responds.In this tutorial, you’ll get hands-on experience with this. Test your website on over 2050 emulators, simulators, and real browsers like Chrome, FireFox, IE, iOS, Android, Safari, and more.Fortunately, Charles Proxy can make network debugging much easier.Charles Proxy sits between your app and the internet. As a result, an end-user might face a bug that remained unexplored while testing on emulators. In some cases, teams cannot mimic some interactions or exact CSS support. Mobile Safari Emulator Download The StarterA VPN can also make problems. Charles will only run for 30 minutes in trial mode, so you may need to restart it throughout this tutorial.Note: If you don’t see any events, you may have not granted permissions or may have another proxy already set up.

Proxies and how they work on macOS and iOS. The middle buttons from the “Tortoise” to the “Checkmark” provide access to common actions, including throttling, breakpoints and request creation. “Record/Pause” is red when Charles is recording events and gray when stopped. “Broom” clears the current session and all recorded activity. Exploring the AppThe user interface is easy to understand without much experience.Many goodies are hidden behind buttons and menus, and the toolbar has a few items you should know about: However, you can split them into separate events.Choose Charles ▸ Preferences and select Viewers. You’ll likely spend most of your time on this screen when debugging your own apps.Charles merges the request and response into a single screen by default. You can still see individual requests by expanding each individual site.Select Sequence to see all events in a continuous list sorted by time. With Sequence selected, the top pane contains a summary of all the recorded network requests, while the main pane contains detailed information about the selected request.With Structure selected, the top pane is replaced by a left-hand pane of the same data, grouped by site address. You might think this makes Charles pointless for all HTTPS events, but Charles has a sneaky way of getting around encryption. You’ll notice one peculiar thing: You can’t see most details for HTTPS events!SSL/TLS encrypts sensitive request and response information. You’ll need to restart Charles for the change to take effect.Try poking around the user interface and looking at events. Java for macIn general, you DON’T want to trust any random certificate, or you could compromise your network security!There are some cases where Charles’ sneaky man-in-the-middle strategy won’t work. Once installed and trusted, Charles will be able to decrypt SSL events!When hackers use middleware to snoop on network communications, it’s called a “man-in-the-middle” attack. Since this certificate isn’t issued by a trusted certificate issuer, you’ll need to tell your devices to explicitly trust it. This is why SSL is so important: Data encryption prevents proxy servers and other middleware from eavesdropping on sensitive information.However, in this case, you want Charles to snoop on your SSL messages to let you debug them.SSL/TLS encrypts messages using certificates generated by trusted third parties called certificate issuers.Charles can also generate its own self-signed certificate, which you can install on your Mac and iOS devices for SSL/TLS encryption. This allows Charles to inspect all network events to and from your computer.Proxy servers are in a position of great power, but this also implies the potential for abuse. When Charles configured your network settings, it changed your network configuration to route all traffic through it. Unfortunately, there isn’t a free version of the iOS app, so you’ll have to buy it if you want to follow along with this section.Note: Don’t want to purchase the iOS app? Worry not! You can skip this section and continue below, where you’ll learn how to route your app’s network traffic to your Mac.Install the app on your device and open it. This is still a common practice you’ll cover, but first, you’ll check out the Charles Proxy for iOS app!Open the App Store on your iOS device and search for Charles Proxy. Since Charles’ key wouldn’t match, the app would reject the communication.Besides logging events, you can also use Charles to modify data on the fly, record it for later review and even simulate bad network connections.Charles is powerful! Charles Proxy and Your iOS DeviceFor years, the only way to proxy traffic from a physical iOS device through Charles Proxy was to tell your iOS device to send all network traffic to your computer. SSL pinning means the app has a copy of the web server’s public key, and it uses this to verify network connections before communicating. :] Installing Charles’ CertificateStill within the Charles Proxy app, navigate back to the initial screen by tapping the back arrow at the top left of your screen twice.
