I have this for the simulator iOS 18.2, device iOS 18.3.2 works OK

Got the same problem today with 18.4 iOS, trying to figure if caused by this plugin, but I'm having exactly the same exception

[sidslog]

if it would help, commenting the content of the following methods allowed the app to run without immediately crashing with Symbol not found error when running from Xcode 16.3:

public func createPdf (configuration: [String: Any?]?, completionHandler: @escaping (_ pdf: Data?) -> Void)
public func createWebArchiveData (dataCompletionHandler: @escaping (_ webArchiveData: Data?) -> Void)
public func evaluateJavaScript(_ javaScript: String, frame: WKFrameInfo? = nil, contentWorld: WKContentWorld, completionHandler: ((Result<Any, Error>) -> Void)? = nil)
public func callAsyncJavaScript(_ functionBody: String, arguments: [String : Any] = [:], frame: WKFrameInfo? = nil, contentWorld: WKContentWorld, completionHandler: ((Result<Any, Error>) -> Void)? = nil)

I feel like it might be a simulator issue. We actually don't have this package in our project. We do have another WebView package though. But interesting enough that the app runs normally on simulator iOS 18.3, and on real device with iOS 18.3 and iOS 18.4, but fails to run on simulator 18.4 for some reason. Failing with exactly the same issue is this ticket has

[TatsuUkraine]

Still trying to find the reason for that

[muccy-timeware]

Same here. Updated to Xcode 16.3 and:

• Simulator iOS 18.4: fails with Library not loaded: /usr/lib/swift/libswiftWebKit.dylib
• physical device iOS 18.4: works properly (it even opens webviews)

[tiees288]

Same to me.
I got an error message from ios simulator when it crashed. Its said about
libSwiftWebkit.dylib not found
So the previous version of simulators has this file.

[mvnthomaz]

Same error here @muccy-timeware

I updated Xcode Minimum deployment target to 15.6 and app opened, but flutter_inappwebview still doesn't work.

[JosephCarrington]

Same problem here.
XCode: 16.3
OSX: 15.3.1

[JosephCarrington]

I ran my simulator as 18.4 and my app started working again, but fluttter_inappwebview does not work

Open your issues on my package. Maintainer of this package abandoned the package once again.
