// These are the only 2 documented reasons why `.init(suiteName:)` might return `nil`:
|
|
|
|
|
|
// - "Because a suite manages the defaults of a specified app group, a suite name
|
|
|
|
|
|
// must be distinct from your app’s main bundle identifier.
|
|
|
|
|
|
// - The globalDomain is also an invalid suite name, because it isn't writeable by apps.
|
|
|
|
|
|
//
|
|
|
|
|
|
// Because we know at compile time that it's neither of those, this is a safe force-unwrap.
