Are you sure you have already searched for the same problem?

Some people open new issues but they didn't search for something similar or for the same issue. Please, search for it using the GitHub issue search box or on the official inappwebview.dev website, or, also, using Google, StackOverflow, etc. before posting a new one. You may already find an answer to your problem!

If this is really a new issue, then thank you for raising it. I will investigate it and get back to you as soon as possible. Please, make sure you have given me as much context as possible! Also, if you didn't already, post a code example that can replicate this issue.

In the meantime, you can already search for some possible solutions online! Because this plugin uses native WebView, you can search online for the same issue adding android WebView [MY ERROR HERE] or ios WKWebView [MY ERROR HERE] keywords.

Following these steps can save you, me, and other people a lot of time, thanks!

Can also confirm this issue with iOS 16.0 installed.

Same issue here, compiles fine on CI (Codemagic) though, so this is also related to Xcode 14 I think?

Same here.

Same here, any solution?

the issue start appearing after upgrading to Xcode 14

This is definitely an issue with upgrading to Xcode 14; see here: https://stackoverflow.com/questions/41904724/using-available-with-stored-properties

To me works change 13 to 14 in podfile

platform :ios, '14.0'

[jeff-odopass]

Downgrading xCode from version 14.0 to previous version 13.4.1 also fix the issue, and looks like a better option according to me as some users still use IOS < 14.
Simply downnload whatever version of xCode you want, install it, and then in xCode > Preferences > Locations select the desired version in the bottom dropdown.

Hope it helps

This solution works for me 👌🏻 👉🏻 https://stackoverflow.com/a/73699790/13821080

Update version in Podfile platform :ios, '14.0' Reset pods cd ios && rm -rf Pods/ Podfile.lock && pod install --repo-update
