FNMNetworkMonitor is a swift iOS networking framework that can be used to monitor the network of an iOS app. It makes debugging the network easy, allowing you to pinpoint the root cause of network related problems in your app and share those requests via email. it can also mock network requests, making it much easier to use incomplete APIs or model specific states for unit testing.
Supports Swift 5 and is bridged for Obj-C compatibility.
pod 'FNMNetworkMonitor'to your
let sessionConfig = URLSessionConfiguration.ephemeral sessionConfig.protocolClasses = FNMNetworkMonitor.normalizedURLProtocols() self.customSession = URLSession(configuration: sessionConfig) FNMNetworkMonitor.shared.startMonitoring()
let request = FNMProfileRequest(urlPattern: .dynamicPattern(expression: "*farfetch.*robots")) let profiles = [FNMProfile(request: request, responses: [request.response(statusCode: 200, headers: [ "Content-Type": "application/json" ], responseHolder: .keyValue(value: [ "FieldA": 1 ]) delay: 0.25)])] FNMNetworkMonitor.shared.configure(profiles: profiles) FNMNetworkMonitor.shared.startMonitoring()
You can also ignore domains using:
This won't record nor intercept requests for this domain.
Make sure to follow steps 1, 2 or 3, depending on the URLSession that runs that particular request.
A debug UI exists that can be used for easy inspection and export of the network:
Generally, the shake gesture is a great way to show/hide the debug view.
Also, different log levels can be applied to see how the requests are navigating through the monitor:
FNMNetworkMonitor.shared.logScope = [.export, .profile, .urlProtocol]
Finally, you can turn on the passive export and the requests will be exported to a json file inside a folder found the Documents application folder.
FNMNetworkMonitor.shared.passiveExportPreference = FNMRecordExporterPreference.on(setting: .unlimited)
If you want to allocate less memory while using network monitor, you can disable media paylod recording:
The project contains a sample app where you can test the tool. You can run the Sample Target Scheme in
NetworkMonitor.xcworkspace to see a working example of the framework.
