AddressBook Dictionary

gistfile1.swift

		var dict = [
			kABPersonAddressCityKey: "Vienna",
			kABPersonAddressZIPKey: "1110",
			kABPersonAddressStreetKey: "Rinnböckstrasse 48/17",
			kABPersonAddressCountryKey: "Austria"
		]
		
		Error on line 1: "Type of expression is ambiguous without more context"
		Error on line 2: "'_' is not convertible to 'StringLiteralConvertible'

ugly but work for me ...

var dict = [
    (kABPersonAddressCityKey as! String): "Vienna",
    (kABPersonAddressZIPKey as! String): "1110",
    (kABPersonAddressStreetKey as! String): "Rinnböckstrasse 48/17",
    (kABPersonAddressCountryKey as! String): "Austria"
]

or

extension CFString {
    func toString() -> String {
        return self as! String
    }
}

var dict = [
    kABPersonAddressCityKey.toString(): "Vienna",
    kABPersonAddressZIPKey.toString(): "1110",
    kABPersonAddressZIPKey.toString(): "Rinnböckstrasse 48/17",
    kABPersonAddressCountryKey.toString(): "Austria"
]

Why the "as!" ?

It seems CFString is not Hashable and cannot be a key. I guess inferring ambiguity is there, because it does bridge to String.

var dict: [String:String] = [
    kABPersonAddressCityKey: "Vienna",
    kABPersonAddressZIPKey: "1110",
    kABPersonAddressStreetKey: "Rinnböckstrasse 48/17",
    kABPersonAddressCountryKey: "Austria"
]

Could you just implement the Hashable Protocol for CFString? Something simple that does the cast and returns the NSString Hash.

Didn't try, but something like:

extension CFString : Equatable, Hashable {
  public var hashValue: Int {
    return (self as! String).hashValue
  }
}
public func ==(lhs: CFString, rhs: CFString) -> Bool {
  return (lhs as! String) ==  (rhs as! String)
}
