Can not sign in OAuth 2.0 in physical device

[serkanozcan]

Hi,

I'm having an issue trying to log in with OAuth 2.0 in physical device. It works when native twitter app not installed on device. But if twitter app is installed on device it stucks after entering username and password like this.

i tried TwitterAPIKit-iOS-sample and same thing happened.

there is a thread in twitter community. They said issue resolved but at my side not resolved.

Hi, there

I found way to fix this
OAuth2CodeFlowPKCEViewController.swift line 39

let state = "<state_here>" // Rewrite your state
to
//random string
let state = String(
String(repeating: "a", count: 128).compactMap { _ in
"abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789".randomElement()
}
)
then it work!!
