How do I get a plist as a Dictionary in Swift?
I am playing around with Apple's new Swift programming language and have some problems...
Currently I'm trying to read a plist file, in Objective-C I would do the following to get the content as a NSDictionary:
NSString *filePath = [[NSBundle mainBundle] pathForResource:@"Config" ofType:@"plist"];
NSDictionary *dict = [[NSDictionary alloc] initWithContentsOfFile:filePath];
How do I get a plist as a Dictionary in Swift?
I assume I can get the path to the plist with:
let path = NSBundle.mainBundle().pathForResource("Config", ofType: "plist")
When this works (If it's correct?): How do I get the content as a Dictionary?
Also a more general question:
Is it OK to use the default NS* classes? I think so...or am I missing something? As far as I know the default framework NS* classes are still valid and alright to use?
You can still use NSDictionaries in Swift:
For Swift 4
var nsDictionary: NSDictionary?
if let path = Bundle.main.path(forResource: "Config", ofType: "plist") {
nsDictionary = NSDictionary(contentsOfFile: path)
}
For Swift 3+
if let path = Bundle.main.path(forResource: "Config", ofType: "plist"),
let myDict = NSDictionary(contentsOfFile: path){
// Use your myDict here
}
And older versions of Swift
var myDict: NSDictionary?
if let path = NSBundle.mainBundle().pathForResource("Config", ofType: "plist") {
myDict = NSDictionary(contentsOfFile: path)
}
if let dict = myDict {
// Use your dict here
}
The NSClasses are still available and perfectly fine to use in Swift. I think they'll probably want to shift focus to swift soon, but currently the swift APIs don't have all the functionality of the core NSClasses.
This is what I do if I want to convert a .plist to a Swift dictionary:
if let path = NSBundle.mainBundle().pathForResource("Config", ofType: "plist") {
if let dict = NSDictionary(contentsOfFile: path) as? Dictionary<String, AnyObject> {
// use swift dictionary as normal
}
}
Edited for Swift 2.0:
if let path = NSBundle.mainBundle().pathForResource("Config", ofType: "plist"), dict = NSDictionary(contentsOfFile: path) as? [String: AnyObject] {
// use swift dictionary as normal
}
Edited for Swift 3.0:
if let path = Bundle.main.path(forResource: "Config", ofType: "plist"), let dict = NSDictionary(contentsOfFile: path) as? [String: AnyObject] {
// use swift dictionary as normal
}
