问题 I've tried tried to install several modules for Python with " pip install <module_name> " command. But I still cannot get how it works. I'am able to use only pygame module, which has been installed with sudo easy_install ("pip install" didn't work). Then I've tried to install another, Eel module and I have got strange results.

问题 I'm writing a Mac (Swift) application on Xcode which gets data from a command and asynchronously changes the stringValue of some text in the window. I already figured out the asynchronous part from here, but I can't seem to figure out how to actually change the text, since Xcode seems to require it to be in viewDidAppear . Unfortunately I can't put the function which runs the command in viewDidAppear since it is called by another file and needs to be a public func (as far as I know). Here are
