But it's really useful particularly in booleans where you can distinguish clearly between 'Yes', 'No' and 'Don't know.' I've seen programmers get themselves into very sticky corners by writing code that doesn't recognize NULL values. I've been away from it for about 7 years, so I'm rusty. It's been a few years but IIRC both C# and Python variables can accept NULL values by default. As with any strongly-typed language, you have to be aware of trying to stuff an incompatible data type into a token. What is that?Īs to optionals, having written 95% of my code for database systems which have the option of defining fields as being able to accept NULL values (some DB's allow null values by default) so I well appreciate the value of variables/fields that can accept NULL values. I'm not familiar with the MBA acronym though. But there seems to be a bit of convergence wrt syntax so that languages that you're not familiar with (unlike 'C' which can be cryptic even to experienced folks) can still be followed, even though the nuances may be missed. I'm an old Python programmer and using even a robust IDE doing Python development can be done on pretty lame hardware!!Ĭlick to expand.Each language is unique in certain ways. TBH I was shocked at how horrible Xcode runs. If I'm right, I'll just have to put off Xcode development until next year when I plan on buying a new Mini running Apple silicon, but thought I'd ask here about this. I'm thinking this will NOT impact the performance I'm seeing in Xcode as I'm assuming the performance issue is this old i5 2-core processor, not disk access. The shop where I bought this can install (relatively inexpensively) a 512GB SSD to replace this slow HD. Even when I set it to run code manually (I'm new to Swift so I'm just doing Playground coding right now) it slows to a crawl.

However, Xcode is another story entirely.

I thought the big test of whether this was going to be powerful enough for my needs was the 3D CAD software I run, but that runs just fine. This is my first Mac, and I've been very impressed with how well it performs despite being 8 years old - it's an i5 2-core w/16mb of memory and a 1TB HD.
