How to capture requests of app on ios I want to see all requests to local network that some app(broadlink E-Control) is doing. I want to see how the app communicate with other devices. P.S:I can modify this network and it's on ios not on macos.
I rely on Charles Proxy for web analysis. It's not clear if that's all you need - but it's a great start for many apps that call API.

How do you watch HTTP requests an iPhone app is making?

If you need actual packet capture, Apple describes how to do that on macOS / iOS / iPadOS and other operating systems here:
