第二个错误的原因是：AuthorizationCreate返回OSStatus。但您将结果分配给不同类型的authFlags

var authRef: AuthorizationRef
var authFlags: AuthorizationFlags = AuthorizationCreate(rights:nil, environment:kAuthorizationEmptyEnvironment, flags:kAuthorizationFlagDefaults, authorization:&authRef)

/AppDelegate.swift:26:89: 'kAuthorizationEmptyEnvironment' is unavailable: use 'nil' instead of this imported macro

/AppDelegate.swift:26:45: Cannot convert the expression's type '$T6' to type 'AuthorizationFlags'

static AuthorizationRef authRef;
static AuthorizationFlags authFlags;
authFlags = kAuthorizationFlagDefaults
| kAuthorizationFlagExtendRights
| kAuthorizationFlagInteractionAllowed
| kAuthorizationFlagPreAuthorize;
OSStatus authErr = AuthorizationCreate(nil, kAuthorizationEmptyEnvironment, authFlags,&authRef);
