PlistLib

Class Plist provides a little DSL around the property lists, avoiding you to query it without casting it to NSArray or NSDictionary and dealing with casting of leaf values and optionality. This class also allows you to compose the plist:

Creating Plist

let plist = Plist(rootPlistEntry: .array([
    .string("first object in array"),
    .dict(["key": .bool(true)])
]))

For convenience, array and dict entries accept optional values, which will be ommited when actual Plist data will be generated:

.dict([
    "key": .bool(true),
    "optional_key": nil,
])

Querying Plist

Basic query:

try plist.root.plistEntry.entry(atIndex: 0).stringValue()  // "first object in array"

try plist.root.plistEntry.entry(atIndex: 1).entry(forKey: "key").boolValue()  // true

try plist.root.plistEntry.dataValue()  // throws an error, because plist entry is array.

If you want to cast array to a Swift generic Array:

let plist = Plist(rootPlistEntry: .array([
    .string("first object"),
    .string("second object"),
]))

let array = try plist.root.plistEntry.typedArray(String.self)  // ["first object", "second object"] 

Same for dicts:

let plist = Plist(rootPlistEntry: .dict([
    "key": .string("value"),
    "another_key": .string("one more"),
]))

let dict = try plist.root.plistEntry.typedDict(String.self)  // [key" : "value", "another_key" : "one more"]
