Note This is a little out of date. Rust has made some progress on some points, however many points still apply.

Philosophy

Progressive disclosure

Swift shares Rust's enthusiasm for zero-cost abstractions, but also emphasizes progressive disclosure. Progressive disclosure requires that language features should be added in a way that doesn't complicate the rest of the language. This means that Swift aims to be simple for simple tasks, and only as complex as needed for complex tasks.

The compiler works for you

simulatorsIdentifiers=$(instruments -s devices |
  grep -o "iPhone .* (.*) \[.*\]" | #only iPhone
  grep -o "\[.*\]" | #only UUID
  sed "s/^\[\(.*\)\]$/\1/" | #remove square brackets
  sed 's/^/"/;$!s/$/"/;$s/$/"/' | #add quotes
  sed '$!s/$/,/' #add comma to separate each element
)

arrayOfSimulatorsIdentifiers=($(echo "$simulatorsIdentifiers" | tr ',' '\n'))
