Hi everyone, my team is developing an iOS app using CoreBluetooth and CoreLocation that includes the below task: Start a BLE scanning to connect to a peripheral when the phone's location enters a specific boundary area. Is there any way for us to implement this task when the app is in background mode or is not opened? Any sharing or advice would be appreciated. Thanks

Hi everyone, How to accept macOS app to open taking screenshot canvas which is familiar with the shortcut (Command + Shift + 4). Thanks!

The project can run on simulator well but it can't run on the iOS devices. I got the error: "error: Build input file cannot be found: '/Users/tantan/Library/Developer/Xcode/DerivedData/Videe-bpukzfmjaxewiuaiolulcqllukjg/Build/Products/Debug-iphoneos/[AppName].app/AppName' (in target 'AppName' from project 'Videe')" Are there any solutions for that? Thanks.

I'm getting the error: ** "Warning: Error creating LLDB target at path '/Users/tantan/Library/Developer/Xcode/DerivedData/Videe-bpukzfmjaxewiuaiolulcqllukjg/Build/Products/Debug-iphonesimulator/[AppName].app'- using an empty LLDB target which can cause slow memory reads from remote devices."** Is there anyone who can explain to me what the reason is and how can fix it? Thanks,
