The requirement of a diploma in software and computer engineering is overall being relaxed as a requirement. If you have the resources to attend college I always recommend doing it as you will never have that time again in your life to spend 4 years of pure education.
If you do attend, I would look at Computer Science, Data and other fields for cutting edge technology.
for some jobs, a two year degree or tech school certificate is enough, other jobs require a 4 yr college degree (BS in computer science as I have or electrical engineering) or even a masters degree. I added an MBA (Masters in Business Administration) a couple of years after graduating from college to 'round out' my technical degree with business knowledge.

You'll find that most employers will require a Bachelors Degree in Computer Science in order to pursue a career in Software Development. That being said, there are other avenues you can take to become a developer. There are now many Bootcamps where you take a specific and accelerated "class" to learn a specific language or system where once completed, you will get a certification that shows that you are knowledgable in a specific technology which you can use in the position that you are applying for.
