In iOS 11, interactive view controller transitions no longer scrub by setting the layer speed to zero
and changing the timeOffset. As a result of this change, implicit animations that occur in places like
-viewWillAppear: (called during an interactive transition) no longer end up “caught in” the animation.

To get the same behavior for table view row deselection as before, you can either use UITableViewController
which implements this for you, or you can implement it manually by deselecting the row in an alongside
animation for the transition (set up in -viewWillAppear: using the transition coordinator).

Here is an example implementation which correctly handles some of the more subtle corner cases:

private class ObserverBox<T>: Hashable {
    typealias Observer = T
    
    private(set) weak var disposable: AnyObject?
    private let objectIdentifier: ObjectIdentifier
    var observers = [Observer]()
    let hashValue: Int

enum Result<T, E> {
    
    case value(T)
    case error(E)
    
    var value: T? {
        switch self {
        case .value(let value):
            return value
        case .error:

final class Timer : NSObject {
    
    private var dispatchTimer: DispatchSourceTimer?

High Order Functions in iOS Swift

Written by Sheldon, please find me with #iOSBySheldon in Github, Youtube, Facebook, etc.

It is exaggerating to say we don't need to use for loop or while loop any more but we can take advantage of the Swift language built in functions to do loops. If I give you a question now. Q: Assuming we have an optional nested array, please calculate the production of the values that are less than 5. let numbers: [[Int]?] = [[1, 3], nil, [2], [5, 10], nil, [4]], what is your best approach to do it?

And you know the solution that I am talking about is following Swift functions:

1. Map
2. FlatMap / CompactMap

{% for type in types.based.JSONAutoRepresentable| %}
// sourcery:inline:auto:{{ type.name }}.JSONAutoRepresentable
    init(_ json: JSON) {
        {% for variable in type.storedVariables where variable|!annotated:"skip" %}
        {% elif variable.type.based.JSONAutoRepresentable %}
        {{ variable.name }} = {{ variable.unwrappedTypeName }}(json["{{ variable.name|camelToSnakeCase }}"])
        {% elif variable.isArray %}
        {{ variable.name }} = json["{{ variable.name|camelToSnakeCase }}"].arrayValue.map({{ variable.typeName.array.elementTypeName.unwrappedTypeName }}.init)
        {% elif variable.type.kind == "enum" %}
        {{ variable.name }} = {{ variable.unwrappedTypeName }}(rawValue: json["{{ variable.name|camelToSnakeCase }}"].stringValue) ?? {{ variable.defaultValue }}
