# Frequently asked questions ## 1. dyld: Library not loaded: /usr/lib/libstdc++.6.dylib - libstdc++ is deprecated for 5+ years, Apple removes it in Xcode 10. This issue has been resolved. ## 2. dyld: Library not loaded: MobileRTC.framework/MobileRTC - Our **iOS SDK** is a dynamic library, please import the **MobileRTC.framework** into: - **Link Binary With Libraries** - **Embedded Binaries** ## 3. d:undefined symbols for architecture x86_64 - If you would like to try iOS SDK on the emulator, or on all architectures (x86_64, i386, etc.), please use the "All" version. ## 4. The view moves up around 20px after leaving a meeting - This case is rare but we have a solution for you. Implement the following function to fix this issue: **viewWillAppear** ```swift - (void)viewWillAppear:(BOOL)animated { [super viewWillAppear:animated]; //For bug that occurs when there are 20 pixels in the bottom while leaving meeting quickly [[UIApplication sharedApplication] setStatusBarHidden:YES withAnimation:UIStatusBarAni- mationNone]; [[UIApplication sharedApplication] setStatusBarHidden:NO withAnimation:UIStatusBarAni- mationNone]; } ``` ## 5. `Unsupported Architecture. Your executable contains unsupported architecture '[x86_64, i386]` - As the [answer on StackOverflow](https://stackoverflow.com/questions/42641806/check-and-remove-unsupported-architecture-x86-64-i386-in-ipa-archive) says: > Apple has started complaining if app contains simulator architectures > during distribution. So if you are going to publish your application through App Store, please use the **device-only** version. Zoom Meeting iOS SDK device only version: <https://github.com/zoom/zoom-sdk-ios>
