This rule applies to stored properties as well as computed properties. Use fileprivate set , private set , and internal set to change the access level of this synthesized setter in exactly the same way as for an explicit setter in a computed property. The example below defines a structure called TrackedString , which keeps track of the number of times a string property is modified:.

The TrackedString structure defines a stored string property called value , with an initial value of "" an empty string. The structure also defines a stored integer property called numberOfEdits , which is used to track the number of times that value is modified. This modification tracking is implemented with a didSet property observer on the value property, which increments numberOfEdits every time the value property is set to a new value.

If you create a TrackedString instance and modify its string value a few times, you can see the numberOfEdits property value update to match the number of modifications:. This restriction protects the implementation details of the TrackedString edit-tracking functionality, while still providing convenient access to an aspect of that functionality.

Note that you can assign an explicit access level for both a getter and a setter if required. The example below shows a version of the TrackedString structure in which the structure is defined with an explicit access level of public. Custom initializers can be assigned an access level less than or equal to the type that they initialize.

The only exception is for required initializers as defined in Required Initializers. A required initializer must have the same access level as the class it belongs to.

A default initializer has the same access level as the type it initializes, unless that type is defined as public. Otherwise, the initializer has an access level of internal. If you want to assign an explicit access level to a protocol type, do so at the point that you define the protocol. This enables you to create protocols that can only be adopted within a certain access context.

The access level of each requirement within a protocol definition is automatically set to the same access level as the protocol. If you define a new protocol that inherits from an existing protocol, the new protocol can have at most the same access level as the protocol it inherits from. A type can conform to a protocol with a lower access level than the type itself. You can extend a class, structure, or enumeration in any access context in which the class, structure, or enumeration is available.

Any type members added in an extension have the same default access level as type members declared in the original type being extended. If you extend a public or internal type, any new type members you add have a default access level of internal. October 28, Debugging Symbols. October 27, Debugging Symbols.

The Files app was introduced in iOS You will not be presented with the option to save to Files when you are on a version less than iOS With that being said, documents can be downloaded to a variety of different apps depending on the settings available on the user's phone and the options you allow.

This is an example of a way to save a document. You can't force it to be downloaded and show up in their Files app. You have to present a UIActivityViewController that shows options on what they can do with that document.

Fundamentally, there are two Foundation types that are especially important when reading and writing files in Swift — URL and Data.

Just like when performing network calls, URLs are used to point to various locations on disk, which we can then either read binary data from, or write new data into. That main bundle can be accessed using Bundle.
