Create a variable total of type Double set to 0. Then loop through the dictionary, and add the value of each integer and double to your variable's value. For each string value, add 1 to the total. For each boolean add 2 to the total if the boolean is true, or subtract 3 if it's false. Print the value of total. var total: Double - 0 44 for (key, value) in SomeDict 45 if value !nt { 46 47 48 49 total value Cannot assign to value: 'value' is a 'let' constant Binary operator'+ cannot be applied to operands of type 'Double' and 'Any' Create a variable tota12 of type Double set to 0.

Answer 1

The first error is generated as the command has been used inappropriately. Its hould be '==' intead of an '='. In the second error, the value is not getting added up to the variable total as it has been jsed inappropriately. It should be 'total=total + value' in order to add the value to the variable 'total'.
