pragma – Learn how to silence a warning in Swift?

There isn’t any basic assemble to silence deprecation warnings in Swift, however there’s a workaround that may be utilized in lots of circumstances.

For instance you could have a way getLatestImage() on class Foo which makes use of deprecated strategies/courses.

Use @obtainable as Daniel Thorpe described to silence all of the warnings inside the strategy:

@obtainable(iOS, deprecated: 9.0)
func getLatestImage() -> UIImage? {
    ...
}

Now you want to name the strategy getLatestImage() with out having a deprecation warning. You may obtain that by first defining a protocol and an extension:

non-public protocol GetLatestImage {
    func getLatestImage() -> UIImage?
}
extension Foo: GetLatestImage {}

After which name the strategy with out a deprecation warning.

If foo is an occasion of Foo:

(foo as GetLatestImage).getLatestImage() // no deprecation warning

If you wish to name a static property/perform of Foo:

(Foo.self as GetLatestImage.Sort).someStaticProperty

The result’s you could have Swift code that makes use of deprecated API with none deprecation warnings.
