For the folks who like the 'where' and do not like the 'guard .. else continue', (also considering in the equation the suggestion of renaming 'where' by 'if'). One can get the 'where' syntax without the 'where'  at the cost of one indentation level and the set of curly braces.

for element in dataArray {
  if condition {
    doWork()
  }
}

versus

for element in dataArray where condition {
  doWork()
}
