No they can’t do everything before writing a line of code. The design and requirements feed into the code and vice-versa over and over through the lifecycle of a piece of software.
Some architecture work and design will be done beforehand, but many details will fall into place as the code is being written, thrown away, adapted, etc.
The idea that code is mere transcription - which I see a lot in these AI discussions - is completely false. Code is a form of low-level design and is where the rubber hits the road.
The best requirements, designs, marketing, etc are worth jack if one fucks up the code. The code is the actual product.
