Notes:

This looks to be the same issue found on an unrelated repo here: https://github.com/fluttercommunity/plus_plugins/issues/1953 which was fixed by updating the minimum ios version to 12+: https://github.com/fluttercommunity/plus_plugins/pull/2169

Update minimum deployment version to 12+ and podspec platform to 12.0 https://github.com/Iterable/swift-sdk/blob/master/Iterable-iOS-SDK.podspec#L15

I am also seeing this issue when compiling with Xcode 15. You can replicate this easily by putting the app into the background and then switch back. Crash happens when the app is put into the foreground.
