Limitations Network Payload Capture is not supported on Espresso and XCUITest automation sessions. NPC does not support capturing network traffic on domains that use a self-signed SSL certificate. Certificate pinning prevents network payload capture. If you want to capture payload for a native application, make sure to disable certificate pinning in your app. iOS devices cannot access any Apple domains (including App Store) in an NPC session. A custom configuration profile is needed to enable the HTTP Proxy on iOS devices. Therefore, NPC does not work if there is another HTTP Proxy configuration profile installed on the device. If iOS devices hosted on a Mac mini are supervised by multiple supervision identities (organizations), only one supervision identity—the one imported into the Mac mini host—will work with NPC.
