When I call the iconv function in the iOS 17.1 beta version to convert from GBK encoding to GBK encoding, character conversion is abnormal. However, in the same scenario, it works fine in iOS 17. Iconv is used extensively in our project. Can you please tell me what changes have been made in the latest version?

I encountered a crash when calling the tabBarView:didSelectIndex: method, and it only happens on iOS 18. Here is crash report: `OS Version: iPhone OS 18.0.1 (22A3370) Report Version: 105 SDK Version: 0.0.4 Exception Type: SIGABRT Exception Codes: #0 at 0x1f0acb274 Crashed Thread: 0 Application Specific Information: *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Layout requested for visible navigation bar, <UINavigationBar: 0x11266ef80; frame = (0 -91; 428 44); autoresize = W; tintColor = UIExtendedSRGBColorSpace 1 1 1 0.8; layer = <CALayer: 0x301e14800>> delegate=0x112670600 standardAppearance=0x3035b3720 scrollEdgeAppearance=0x3035b3b10, when the top item belongs to a different navigation bar. topItem = <UINavigationItem: 0x14309cf00> title='' titleView=0x15b1af700 style=navigator leftBarButtonItems=0x301c08940 rightBarButtonItems=0x301caa180, navigation bar = <UINavigationBar: 0x11266e080; frame = (0 -91; 428 44); autoresize = W; tintColor = UIExtendedSRGBColorSpace 1 1 1 0.8; layer = <CALayer: 0x301e1d0a0>> delegate=0x112670000 standardAppearance=0x30355ae60 scrollEdgeAppearance=0x30355aed0, possibly from a client attempt to nest wrapped navigation controllers.'
