cocoa - key/value pairs by name in Dictionary in Swift -
is possible access key
, value
of single dictionary
entry key & value, not 0 & 1?
in example:
let rockyplanets: dictionary<string, int> = [ // alphabetical order "earth": 3, "mars": 4, "mercury": 1, "venus": 2 ] eachplanet in rockyplanets { println("\(eachplanet.0) @ position \(eachplanet.1)") }
how can access key/values key or value (not index) in fashion:
for eachplanet in rockyplanets { println("\(eachplanet.key) @ position \(eachplanet.value)") }
is looking for?
for (key, value) in somedict { // ... }
in case:
for (planet, position) in rockyplanets { println("\(planet) @ position \(position)") }
