问题
I can't install app on my simulator after update to MacOS Catalina, it was fine on earlier versions. But Now when I try to run the app installed in the simulator I get this popup.
I have changed system Security & Privacy setting using this command in the terminal sudo spctl --master-disable and now my it looks like this.
But even after this I can't run the app, any idea, suggestion ?
My Xcode version is 11.1 & target iOS version is 13.1, app runs smoothly when ran using xcode, but exported app is causing this issue.
回答1:
I was able to solve this problem by running the following command.
xattr -dr com.apple.quarantine <path_to_app>
It turns out if you download app using some browser then it adds a flag which is considered a security threat in catalina, running this commands solves the issue.
