After installing Xcode

阅读更多关于 Why does the LLDB Debugger constantly fail to attach?

I have seen a lot of answers for this question: error: failed to attach to process ID as switch to GDB . But no one addresses the reason of why it happens?

Alternatively, how can I set GDB as my default debugger without changing it manually when creating the new projects? System Info: OS: Lion RAM: 5GB XCode: Version 4.6 (4H127) Device: Mac mini My localhost setting: Make sure you have localhost mapped to 127.0

阅读更多关于 iOS Simulator would like to access microphone every time

问题 Since the update to macOS Mojave, I get this alert every time I run on the simulator: "<AppName>" would like to access the microphone. It is stopping the simulator from running!

阅读更多关于 iOS simulator only uses the first app folder for localStorage files but creates a new app folder for everything else

I'm trying to delete the localStorage files of my app, and to do that I need to know where the app stores its cached data, but I don't consistently get the correct path in the iOS simulator, this only works consistently on the phone.

If I delete the entire /Users/john_doe/Library/Developer/CoreSimulator/Devices/ and start the app NSSearchPathForDirectoriesInDomains finds the correct folder. On the next build the path that is returned is the new application directory, but the iOS simulator
