Swift is collapsing under the weight of its increasing complexity. So many, many special cases & they keep adding more!

As a developer it becomes so very hard to reason about code behaviour. This is especially true with concurrency, which was meant to simplify concurrent operations, but in actual fact is a nasty can of worms. In an effort to "hide the complexity" it just introduces a huge amount of unexpected & hard to grok behaviour. The new "immediate" Task behaviour & non-isolated async behaviours are good examples of this.
