TLS 1.0 and 1.1 deprecation
Since September 30, 2021
TLS 1.0 and 1.1 has been deprecated on Apple platforms as of iOS 15, iPadOS 15, macOS 12, watchOS 8, and tvOS 15, and support will be removed in future releases. If your app has enabled App Transport Security (ATS) on all connections, no changes are required. If your app continues to use legacy TLS 1.0 or 1.1, please make plans to transition to TLS 1.2 or later. We recommend supporting TLS 1.3, as it’s faster and more secure.
